What processes can be disabled in windows xp. Windows XP System Services

Acceleration work interests everyone. It’s not uncommon for people to come to us with the question: “How speed up Windows XP?. To answer this question and tell everything we know on the topic " Windows XP acceleration"we will have to write more than one article, so today we will talk about one of the methods - disabling services

Although Microsoft recommends using the default system settings, this is not very convenient for most users. The fact is that some of the services included in the “default” set not only waste valuable resources, but also pose a certain threat to computer security. For example, the “Remote Registry Access” service. It is unlikely that ordinary users often need it, but attackers can successfully take advantage of it. Acceleration OS operation is achieved by disabling unused services.

Below is a list of rarely used services. Turning them off will not lead to unstable operation of the computer, but it may speed up Windows XP.

DHCP client. With this service, a computer obtains an IP address by requesting a DHCP server. In large companies where staff cannot independently set up a connection to the network of work computers, this service is indispensable. At home, it is most often of no use, so you can turn it off. However, you need to be careful: if the provider uses cable networks to provide Internet services, then most likely the IP addresses are assigned by a DHCP server.

Remote Registry Service. Using this service, you can change registry entries remotely (over a network). It was already noted above that this service can pose a significant threat to computer security.

Wireless Zero Configuration. Used to automatically configure wireless networks, in other words, WiFi connections. If in this moment This is not relevant for you, then you can safely turn it off.

QoS SRVP. QoS technology allows you to divide a network channel into bandwidths, but in most cases this is successfully handled by an ADSL + splitter combination at the hardware level.

NetMeeting Remote Desktop Sharing. With this service, you can create desktop connection sessions through the Microsoft Net Meeting client. If this feature is not used, it is better to disable this service, as it may pose a security threat to the OS. For the same reason, this service is not available on some unlicensed Windows discs.

Remote Procedure Call (RPC) Locator. Using this service, RPC clients find RPC servers, the service opens TCP ports: 139 and 445, which can be exploited by malware. So, if you do not use this service, it is better to disable it.

Task Scheduler- an absolutely necessary service if you regularly run any programs on a schedule. For example, a media player at six in the morning as an alarm clock. In other cases, the service can be disabled painlessly.

Time service provides date and time synchronization on computers on the network. How much do you need your computer to ask your neighbors what time it is and reset its clock?

Error Logging Service. It is this service that sends error reports to Microsoft.

IPSEC Services. Using the Oakley (IKE) driver, manages IP security policy. Needed when using a VPN (pseudo-local network).

Themes- ensure the functioning of all Windows themes other than Classic. Those. this service is actually responsible for rendering beautiful windows, smooth scrolling of lists and other beauties of Windows XP. If you are using the standard classic theme, then you can safely disable this service. It is also worth noting that this is one of the most “gluttonous” services, disabling which can significantly speed up Windows XP

Security Center. This service does not provide any protection; its main function is to notify the user that system auto-update, firewall, etc. are disabled.

Mechanism disabling services next:
Right-click on the “My Computer” icon -> “Manage” -> “Services and Applications” -> “Services” -> select the desired service -> “Stop”
In order for the changes to be permanent, in the service properties you need to change the startup type from “Auto” (“Manual”) to “Disabled”.

As stated above, Windows XP acceleration this is a delicate matter, so if the above actions did not have the expected effect and speed up Windows XP If it didn’t work, don’t worry - bring your computer to us and we will definitely make it work at full capacity.

On the topic of optimizing Windows performance, we recommend that you read the article How to increase virtual memory and optimize the page file

Include ($_SERVER["DOCUMENT_ROOT"].."/templates/rss.php"); ?> include ($_SERVER["DOCUMENT_ROOT"]."/templates/feedback.php"); ?>

By changing various options and parameters without understanding what and how they can affect, it is very easy to ruin everything.
You need to take care of your safety, fortunately, Windows XP has all the backup tools for this: Backup, System Restore, ASR.

Bringing back the classic Start menu style:

Right-click on the taskbar, "Properties", "Start Menu" tab, select "Classic Start Menu", "OK"

Right-click on an empty area of the screen,
menu item "Properties", tab "Appearance". Select " Classic style"windows and buttons. Click the "Effects" button. Uncheck all the checkboxes except the last one.

In the "Control Panel" select "Folder Options".
In the window that opens, select “Use regular Windows folders” - this will save us from unnecessary decorations that slow down the navigation process.
Go to the "View" tab. Check the box "Do not cache thumbnails" - otherwise, when viewing folders with graphic files, Windows will litter it with miniature copies of pictures; check the box "Display the Control Panel" in the "My Computer" folder; uncheck the box "Remember display settings for each folders" (optional) and "Hide protected system files"; select the option "Show hidden files and folders"

In the "Control Panel" select "System".

In the "Advanced" tab, in the "Performance" frame, click on the "Options" button. In the window that opens, select " Visual effects" and uncheck all the boxes

Disable error reporting.
Call "System Properties" and on the "Advanced" tab - "Error Reporting", select "Disable Error Reporting"

Uninstall Windows Messenger. Every time the system boots, Messenger also starts, slowing down the boot process and consuming system resources. In the command line Start - "Run" type the following:

RunDll32 advpack.dll,LaunchINFSection %windir%\INF\msmsgs.inf,BLC.Remove

And click “OK”. After you restart Windows Messenger on your computer, you will no longer find

Setting the optimal paging file value
"System Properties" - "Advanced" - "Performance" - "Advanced" - "Virtual Memory" - "Change". It is recommended to set the initial size and maximum to the same. For normal work, it is enough to multiply the available memory by 1.5. Games require two, two and a half times more memory. Details

Reducing the delay time before expanding submenus. Start - "Run" and type "regedit". In the registry we find
HKEY_CURRENT_USER\Control Panel\Desktop
Change the MenuShowDelay parameter from 400 to 0.

Remove unnecessary programs from startup
Start - "Run" and type "msconfig". "Startup" tab - uncheck the boxes next to those programs that you do not need

Clear the "prefetch" folder - C:\windows\prefetch.
This folder contains links to launched applications and programs. Some of the links are no longer used or are rarely used, but when loading, the system checks for the presence of links in this folder. Over time, the number of links in this folder increases so much that the system takes more time to scan. Cleaning out this folder will speed up your system performance. It is not recommended to reboot the system after cleaning the folder. This will degrade performance

Disable indexing.
Open “My Computer,” right-click on the hard drive icon and select “Properties.” In the window that opens, uncheck “Allow disk indexing for quick search.” After clicking the “Apply” or “OK” buttons, a new window will appear in which you will be asked whether to apply the selected attributes only to the current drive or to attached files and folders too. As a result, the system will run a little faster. Applicable only for drives with NTFS file system

Windows XP considers "Zip" files to be folders
this is convenient if you have a fast computer. On slower systems, you can force Windows XP to disable this feature (if you have another archiver, such as "RAR") by typing "regsvr32 /u zipfldr.dll" at the command line. You can return everything back with the command "regsvr32 zipfldr.dll"

Changing the priority of interrupt requests (IRQs).
If you increase the priority of CMOS memory and real-time clock, you can increase the performance of all elements of the motherboard. Open "System Properties" - "Hardware" button "Device Manager". Now open the properties of the device you are interested in and select the "Resources" tab. Here you can see which IRQ number is used by the selected device. Note the interrupt number and close all windows. Run RegEdit. Find a section

HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/PriorityControl
Create a new DWORD key IRQ#Priority (where "#" is the IRQ number) and set it to "1". For example, in our case, IRQ08 is reserved for System CMOS. Therefore we created the IRQ8Priority key

Disabling an unused POSIX subsystem
may increase operating speed slightly. Launch "Regedit". Open the branch in the registry editor

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control SessionManager\SubSystems
and remove the Optional and Posix lines.

Do not record last accessed files (NTFS only).
Speeds up access to directories with a large number of files. In the registry editor "Regedit"

HKLM\SYSTEM\CurrentControlSet\Control\FileSystem
NtfsDisableLastAccessUpdate parameter value "1"

Do not use a page file to store the system kernel.
By default, WinXP dumps the kernel and system drivers into the page file when they are not in use. Using this option, you can tell WinXP to keep the kernel and system drivers always in memory. Launch "Regedit"

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
parameter DisablePagingExecutive, "1" - do not use the paging file to store the system kernel, "0" - use

Automatically unload unused libraries.
This feature will help free up memory. Launch "Regedit"

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
AlwaysUnloadDLL parameter, value "1" - unload libraries, value "0" - do not unload. Note: the system may become unstable when this option is enabled.

Use fast user switching.
If the option is enabled, then when switching to another user, the current user's programs will continue to work. Otherwise, programs will automatically turn off when the user logs out, and the computer will work faster with the next user. Launch "Regedit"

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
AllowMultipleTSSessions parameter, value "1" - use fast user switching

Disable the built-in debugger Dr. Watson.
If the option is disabled, then if there is an error in the program, a corresponding error message will be displayed with the OK and Cancel buttons; when you click OK, the application ends, and when you click Cancel, the debugger starts. In the registry editor "Regedit"

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug
set the "Auto" parameter to "0"

Do not keep track of document opening history.
Do not keep a history of "Recently Used Documents". Windows XP creates shortcuts to launched programs in the Documents and Settings\%USERNAME%\Recent folder. You can disable this feature if you do not use them. Launch "Regedit"

parameter NoRecentDocsHistory, value "1" - history is not maintained

Automatically terminate frozen applications.
This option is used to automatically close all hung programs without any warning. Convenient when shutting down your computer; if the application is not responding, you don’t have to press a button to shut it down. Launch "Regedit"

HKCU\Control Panel\Desktop
AutoEndTasks parameter, value "1" - automatically end frozen applications, "0" - wait for user input

Disable the low disk space message.
Do not display a message about low disk space. It makes sense to use this option on small disks. Launch "Regedit"

HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
parameter, NoLowDiskSpaceChecks, value "1" - message disabled, "0" - enabled

Block automatic updates in Windows Media Player.
Windows Media Player periodically establishes a connection via the Internet to check for the existence of a new version of the program (Tools-Options-Automatic updates frame). You can disable this feature in Windows Media Player. Launch "Regedit"

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsMediaPlayer
parameter DisableAutoUpdate, value "1".

Release of the channel (bandwidth) reserved for the QoS service.
Windows XP by default allocates part of the Internet channel for Quality of Service (QoS). The purpose of QoS is to improve the traffic distribution of programs written with the QoS API in mind. You won’t find these programs, so reserving a channel for an unnecessary service is an unaffordable luxury. In order to free up the already narrow channel of the domestic connection to the Internet, in the Start menu -> Run, launch the group policy editor gpedit.msc.
To run, you need to be a system administrator. In the "Computer Configuration" section, select "Administrative Templates", then "Network" and then in the right pane, select "QoS Packet Manager" and double-click on it. Select the "Limit reserved bandwidth" option and double-click on it again.

In the window that opens, turn on Enabled, and then specify the channel limit as a percentage equal to zero, click "OK" and exit the program. Open "Network Connections" in the "Control Panel", open the properties of your connection and on the "Network" tab, make sure that the "QoS Packet Scheduler" protocol is enabled. If it is not there, then add it from the list and restart your computer.

Owners personal computers With limited computing resources, people often try to improve operating system performance by disabling services. By disabling services, the PC user can increase and improve the performance optimization of the old computer, but by disabling the services that are needed for proper operation operating system, problems may occur.

Problems caused by disabling a particular service can be very different and lead to different consequences. For example, if we disable a service called " Plug and Play", this will lead to the fact that you will not be able to connect new peripherals and components to the PC.

To help our readers optimize PC performance by disabling unnecessary services, we have prepared material in which we will describe in detail the solution to this problem in the Windows 7, 8 and XP operating systems.

Optimizing performance in Windows 7

In the operating room Windows system 7 There are two ways to disable services. The first method allows us to solve our problem through add-in in Control Panel, the second - through console. To use the first and second methods, we first determine which services we can disable without harm to the system.

Here is a list of services with detailed description, which we can disable without harm to the system:

Print Manager- if your PC does not have a working MFP or inkjet, then feel free to turn it off;
Tablet PC input service- is responsible for supporting touch screens in tablets and touch monitors; if your computer does not have a touch screen, then feel free to disable it;
Remote Desktop Service- allows other users to connect to your desktop remotely and work on it; if you do not use the remote desktop, then feel free to disable it;
Computer Browser- creates a transfer list that is sent to other PCs on the network. This list is needed to determine the main computer on the network. For a home user, this does not matter, so the computer browser can be disabled;
IP Ancillary Service- responsible for new version IPv6 protocol. Since in most cases our providers still use the old IPv4 protocol, we can disable this service without consequences;
Remote registry- used to remotely edit registry entries. In most cases, this feature is not needed by a home user, so feel free to disable it;
Terminal Service- is responsible for access to remote terminal servers; if you do not use RDP, then disable it;
Disk Defragmenter- thanks to this service, the operating system automatically defragments the disk, but if you have a third-party defragmentation utility installed, for example, Defraggler, then feel free to disable it;
Secure storage- provides secure storage digital signatures, private keys and encrypted data. If you do not use encrypted information, then disable encrypted storage;
BitLocker Drive Encryption Service- used to encrypt local disks. If you do not use disk encryption, then disable BitLocker;
Bluetooth support- ensures the operation of the Bluetooth transmitter and data transmission through it. If your PC does not have a Bluetooth transmitter, then feel free to turn it off.

To use the first method, we must go to the program execute " Execute" and enter the command "services.msc" into it. You can run the program through the menu " Start"or using the keyboard shortcut Win + R

After executing the command, we will be taken to the required add-in. I would also like to note that this method of opening this add-on works on XP and Windows 8.

For example, we need to find and open in this add-on " Print Manager».

To completely stop " Print Manager", select the launch type " Disabled" and click the Stop button. After these steps, the service will go into the " Stopped».

If in the future you need to connect the printer to your computer, then leave the print manager startup type in the “ Manually».

Now let's look at the console stop of unnecessary services. First of all, let's launch the console as Administrator. To do this, we enter in Windows search 7 “CMD” and launch the console as Administrator, as shown in the image below.

In a running console, let's also try to stop " Print Manager" To do this, type the command in the console: net stop "spooler" and execute it.

After this, the spooler process will stop. In the same way, other processes are turned off through the console.

From the examples it is clear that stopping an unnecessary service is quite easy, so even a novice PC user can cope with this task.

Optimizing performance in Windows 8

For Windows 8, disabling services looks the same as in Windows 7, even the add-on has remained virtually unchanged.

Therefore, it makes no sense to describe a similar process. The only difference between Windows 7 and Windows 8 is the number of services that can be disabled. In addition to the services described in the previous example, in Windows 8 you can also disable the following:

Changed Link Tracking Client- this service is designed to monitor changeable parameters in installed programs. For example, adjusting the address of a shortcut that has been moved to another location;
BranchCache- technology that helps companies speed up data exchange in a large network;
Hyper-V- you can disable all services in the control panel add-on if you do not use virtual machines on your computer;
Microsoft iSCSI Initiator Service- provides access to computers via the iSCSI protocol;
Family Safety- when using family safety in eight, it is better not to disable this service.

The list shows which services can be disabled in Windows 8 without harm to the system.

Getting better performance by disabling unnecessary services in XP

The principle of disabling services in Windows XP is the same as in seven and eight. If you have had experience disabling Windows XP services, then you can easily do this in Windows 7 and 8. The only difference will be the add-in and command line interface.

Also, the number of services in XP that can be stopped painlessly is significantly lower than in Windows 7 and 8. Below is a list of services that you can stop without harming Windows XP:

Error Logging Service- allows you to send a report about OS and program errors to Microsoft via the Internet;
Remote registry- described in the first example;
Computer Browser- described in the first example;
SSDP Discovery Service- detection of network devices with UpnP protocols; Disabling this service is not critical for a home user;
Remote Desktop Service- described in the first example.

The example describes only a small part of the services that can be disabled.

We advise you not to disable services in Windows XP unnecessarily, since this OS consumes few computer resources. By disabling unnecessary services on a computer running Windows XP, you will rarely notice a noticeable improvement in performance.

In the material reviewed, we looked at the main services, disabling which is safe for the functioning of Windows 7, 8 or XP. You can also disable at your own risk even more unused and running services in the Control Panel add-on, most of which cannot be disabled.

Be careful when performing such experiments as they affect system stability and performance.

Before disabling a service not described in this material, it is better to familiarize yourself with its purpose in the description in the Control Panel add-on.

I would also like to advise novice users conducting similar experiments: create a system restore point and make a backup important data.

Video on the topic

Services running by default consume valuable resources, thereby significantly reducing the performance of the system as a whole. Thus, by disabling some, we can significantly increase the speed of operation Windows. I would like to note that disabling these services will not affect the stability of the system in any way. I think freed 150-200 MB random access memory You will need them for more necessary programs.

To open the Service Manager, click Start > Run, in the window that appears, enter services.msc and click Ok.

IMPORTANT! I strongly recommend creating a system restore point before disabling unnecessary services, or you can simply save the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services (to do this, right-click on the specified section and select "Export"). If something happens, you can quickly return everything to its original state.

Here is a list of Windows XP services that you can safely disable.

Remote Desktop Help Session Manager- Manages the capabilities of Remote Assistance. Once this service is stopped, Remote Assistance will no longer be available. Before stopping a service, in the Properties window, Dependencies tab, check the service dependencies. It is recommended to disable this service, because... in idle mode it takes up 3 to 4 MB of RAM. This service, if enabled and running, may slightly slow down your computer. This service, if enabled and running, reduces the level of system security.

Error Reporting Service- Allows you to log errors for services and applications running in a non-standard environment. This service manages a system for collecting messages about unexpected system failures. The service consumes quite a large number of system resources, so if your system is stable, you can disable it. This service, if enabled and running, can greatly slow down the computer, for example, the speed of access to the hard drive can seriously slow down. The operation of this service does not in any way affect the security level of the system.

Distributed Transaction Coordinator- Coordination of transactions spanning multiple resource managers such as databases, message queues and file systems. If this service is stopped, such transactions will not be completed. If this service is disabled, any services that explicitly depend on it will fail to start.
This service is required to access heterogeneous data sources within a single transaction. You may also find messages about this service being disabled in the Event Log. In the future, this service may be required for .NET applications. If you use Message Queuing or SQL Server, then this service must be enabled. This service, if enabled and running, may slightly slow down your computer. The operation of this service does not in any way affect the security level of the system.

Remote Registry Service- purpose of the service - support for changing registry entries over the network. Be sure to disable this service. It poses a real threat to the security of your computer.

Smart cards- This service controls access to smart card readers. If this service is stopped, this computer will not be able to read smart cards. It is recommended to disable this service.

Telnet- Allows a remote user to log on and run programs, supports a variety of TCP/IP Telnet clients, including computers running UNIX and Windows operating systems. If this service is stopped, the remote user will not be able to run programs. If this service is disabled, any services that explicitly depend on it cannot start. When this service is disabled, users will not have remote access to programs. This service, if enabled and running, may slightly slow down your computer. If this service is enabled and running, the level of system security is significantly reduced.

Wireless Zero Configuration- Provides automatic configuration of 802.11 adapters. If there are no wireless adapters connected to your computer, it is recommended to disable this service to save system resources.

QoS SRVP- Provides notifications on the network and local traffic management for QoS programs and control programs. This service provides traffic control on the network using IPSEC, programs, and adapters that support QoS technology. The QoS packet scheduler is automatically installed for each TCP/IP connection. It is recommended to disable this service, because... in 99% of cases it is not necessary. Many articles on the Internet indicate that QoS services reserve 20% of the network bandwidth and do not allow this 20% to be used for network work. It's a delusion. You can read more about this in technical article q316666 on the Microsoft website.

Here is a small list of Windows services that can slow down your computer. Of course, this list can still be replenished, but I think it’s better not to overdo it and do everything in moderation.

Good day to all. In this article we will talk about what you can disable services in Windows In most cases.

I have already talked about increasing the speed of this already fast operating system.

Today I will tell you another way to sharpen this system using, as you understand, a story about disabling unnecessary services, and I will also give a little theory about what these services actually are.

Let's get started.

Introductory. What are services?

Services are programs that run in the background without any graphical interface. Each service is responsible for supporting a particular function (for example) of the computer, and some have system parameters and without them the OS will not be able to work.

However, other services can be safely disabled, saving money, reducing the load on and thereby increasing the speed of the operating system, especially on weak and medium-sized computers. In general there are t

To view the list of services and generally control their operation in every possible way, you need to open " Start -> Settings -> Control Panel > Administrative Tools > Services". In front of you you will see a list of services, each of which can be stopped, started, and also assigned launch parameters:

Auto;
Manually;
Disabled.

With the help of these settings we will sharpen our system.

How to disable services and why?

Before I tell you which services to disable, I will explain how to disable it. On the desired (read which one you need below) service, double-click the mouse button and, if the service is running, in the window that appears, click " Stop " , after which in the graph " Startup type " select the value "Manually".

If it was not started and the startup type was Manual, then nothing needs to be changed, or you can disable such services, but there is little point in this. Before going any further, it's worth understanding that each service usually has a description and it's possible to accidentally disable the wrong thing. I recommend that you carefully write down everything that you disable and think three times about why you are doing it.

So that later, if something happens, it would be possible, on the contrary, not to disable the services, but to enable them and restore the computer’s functionality

List of services to disable

Now let's move on to the list of which services to disable, which ones not, and perhaps why:

First of all it's " SSDP Discovery Service" And " Generic PnP Device Node". They are needed when connecting a "smart" household appliances to the computer and series universal devices. We have almost nothing like this in Russia yet;
Many people have probably never used system error logs and don’t even know where they are located, let alone why they are needed. Therefore, these services can be disabled. Namely: " Performance Logs and Alerts", "Error Logging Service" and "Notification of system events". They all write system errors to log files stored in the %SystemRoot%\SYSTEM32\WINS directory;
If you live at your computer in splendid isolation and there are no other users in the system, then
you can remove services" Secondary login" And " Fast User Switching Compatibility";
If you do not have a Wi-Fi adapter for wireless communication with the Internet, then disable the “Wireless Settings” service;
If you do not use search through My Computer, or you use it but rarely, then disable " Indexing service", the opening of all files will speed up, the system will take up less disk space, but the search using the built-in Explorer tools will be much slower;
It is likely that your computer does not have a printer. In this case, you can disable the service" Print Manager";
Do you know what a planner is and use it? No? Then disable the service of the same name "Scheduler";
If there is no local network (including a dedicated Internet line), then you can get rid of servicesg Telnet, NetMeeting Remote Desktop Sharing, "Remote Desktop Help Session Manager", "Network DDE Manager", "Security Account Manager", "NetBIOS support module over TCP/IP", "Computer Browser", "Annunciator", "Workstation", "Server", " Exchange Folder Server", "Network login", "Network DDE Service", "NLA Network Location Service", "Messaging service", "Cryptography Services", "Terminal Services", "Remote registry", "Background Intelligent Transfer Service";
Most likely you rarely use the services " Automatic update", "WMI Performance Adapter", "Smart Card Support Module", as well as "Smart cards" and " Portable media device serial number". If this is the case, or you don’t know anything about them at all, then turn them off too;
Do you have an uninterruptible power supply? If not, then disable the service" Uninterruptable power source"

That's all. You can disable the rest at your discretion, once again, after reading the description of the service first. And write down what exactly you are turning off.
