Disabling unnecessary Windows XP services. How to speed up Windows XP? What Windows XP services can be disabled? Generic PnP Device Node

While XP is running, there are dozens of services that provide certain functions of your Windows, and all of them eat up a lot of RAM.
Many of these features will never be useful to you, so you can turn them off.
You can view the entire list of services by running Start -> Settings -> Control Panel -> Administrative Tools -> Services or run services.msc from the command line.
Active at the moment are only those that have the value "Working" in the "Status" field.
In order to change the startup type, you need to double-click on the desired service and on the "General" tab find the "Startup type" field, in which you can select the mode we need.
There are only three options: auto - it always works, manually - it starts as needed by the operating system itself, disabled - it does not start at all.
It is necessary to disable services very carefully, it is better to leave something superfluous than to remove a component necessary for operation. If in doubt whether to disable the service or not, then it is better to set the “Manual” mode so that the operating system can load the required service if necessary.
Otherwise, errors may occur in the operation of programs up to the crash of the system, access to some features will be lost, and it will simply become uncomfortable to work.
So before the experiment, just in case, make a backup copy of the registry key that is responsible for starting system services - then, in case of any problems, you can simply apply the received * .reg file and fix everything.
When recommending disabling a particular service, I proceed from the premise that the configuration is carried out on a normal home computer. Otherwise, you need to proceed from the actual operating conditions of the computer.

Now about the services themselves:

DHCP Client (DHCP Client)- in principle, if you have no mention of a DHCP server in your network connection settings (including the Internet), then you can set the start to Manual, but it's better, nevertheless, to leave it as Auto.

DNS client (DNS Client)– if the computer is not connected to the Internet, you can install it Manually.

NetMeeting Remote Desktop Sharing- Allows verified users access to the desktop - disable for particular harm.

plug and play"Better not touch anything!"

QoS RSVP- it is unlikely to be needed for a local machine, so leave Manual, and if the machine is connected to any network (local, Internet), then this is just a very harmful service that takes up 20% of the traffic by default !!!, but simply by turning it off , you won't achieve anything. As for this service, not everything is so simple, therefore, without going into details, we just leave it as it is.

telnet- if you need someone to remotely run programs on your machine from the console, then, of course, you can leave Manual as well. For everyone else - Disable.

Windows Installer- it is better not to disturb this service, so let it work Manually.

IPSEC Policy Agent– the service is needed only if the computer is connected to a Windows 2000 domain. Otherwise, it is better to set it to Manual.

Remote Access Auto Connection Manager- You can set it to Manual or disable it altogether.

Logical Disk Manager- You can set the startup type to Manual.

Print Spooler- if you do not have printers (including network ones), then you can disable the service altogether - you still do not have to print files.

Remote Access Connection Manager- for local computers, in principle, you can set it to Manual, but if you are connected to the network, it is better to leave Auto.

Network DDE Manager (Network DDE DSDM)– Initially it is set to Manual. Well, let it be.

Utility Manager- I hope you didn’t even install “Accessibility”, so feel free to turn off this service. Of course, if you like how the message pops up, if you press Shift five times in a row, then you can leave it.

Security Accounts Manager– for local computers and network machines for which security information for local user accounts is not obtained from the network, you can set it to Manual. Otherwise - Auto.

Event Log- if you have never looked into the log file of the system and do not even know where it is, then disable the service. More advanced is recommended to leave Auto.

Protected Storage- it is this service that stores passwords to your mailbox, and not only to it. You can switch to Manual mode only if the computer is not connected to either the Internet or a local network. Windows Management Instrumentation is a pretty important service. Let her work better all the time.

Uninterruptible Power Supply- if you have a UPS with a control interface connected to a computer, then set it to Auto, otherwise - Disabled.

Distributed Link Tracking Client- needed only for computers in the Windows 2000 domain. For all others, set it to Manual.

Distributed Transaction Coordinator- the description of this service sounds too scary, so it's better to leave it Manually.

Remote Procedure Call (RPC) Locator– manages the RPC naming service database. Initially stands Manually - well, let it stand.

Routing & Remote Access- on non-network computers, set Disabled, if the computer is on the local network, then you can also turn it off - this is unlikely to be needed, in extreme cases, the admin will explain to you the depth of your delusion and set the mode you need.

Smart Card Helper- I doubt that you have a smart card reader, so set it to Manual.

Computer Browser- if the computer is not connected to the local network, then you do not need this service, so set it to Manual.

Internet Connection Sharing– the need for this service is highly questionable in any case.
Even if computers on your local network access the Internet through you, then for these purposes it is better to use special programs that provide a lot of additional features. Well, if the computer is not connected to the network at all, then all the more it is necessary to disable this service.

Alerter- leave Manual for computers on the local network, you can disable it on your home computer.

Performance Logs & Alerts- this service is not so important as to put it in Auto mode, so leave it Manually.

Task Scheduler- if you use the scheduler, then, of course, leave Auto, otherwise - Disabled.

NT LM Security Support Provider- Provides security for programs that use remote procedure calls (RPC) over transports other than named pipes. It is better to leave Manual.

Workstation- needed for other services, leave Auto.

Windows Management Instrumentation Driver Extensions– the service can be set Manually.
Server (Server) - for computers that are not connected to the local network, this service can be disabled.

Exchange Folder Server (ClipBook)- Leave Manual. For non-networked computers, you can disable it altogether.

Net Logon– has a default value of Manual. It's better not to change it.

Network Connections- oddly enough, but even if set to Manual, it is still always running. If you are not connected to a local network and do not access the Internet from this computer, then you can turn it off, for other cases it is better not to touch it.

COM+ Event System- it is recommended to set the value of this service to Auto, so it is better to listen to the recommendations.

RunAs Service- Do you often have to run applications on behalf of other users? Feel free to set it to Manual.

Logical Disk Manager Administrative Service– the service is started Manually, it is better not to change this value.

Windows Time Service (Windows Time)- sets the computer clock. Leave Manual.

Indexing Service- indexes the contents and properties of files on the computer, to ensure their fast search.
But, in my opinion, it is better to search for files on a computer using FAR, Windows Commandera, or other programs more adapted for this. So it's better to disable the service.

TCP/IP NetBIOS Helper Service– for a computer that is not connected to the local network, disable, for the rest – Auto.

Network DDE Service- Manually.

Message service (Messenger)– set Auto or Manual for computers connected to the local network. You can turn it off on your home computer.

Remote Registry Service– would you trust someone to remotely poke around in your registry? Me not. Moreover, even leaving such a service is harmful, so definitely turn it off!

Fax Service– if you do not have a fax modem connected or you do not use it to receive fax messages, then you can safely disable this service.

Smart cards (Smart Card)- smart cards have already been mentioned above, so the actions are similar to the "Smart card support module" service.

Removable Storage- if you do not have removable media such as ZIP, LS-120, then disable this service. Otherwise - Auto.

Telephony- provides support for the Telephony API (TAPI) for programs that manage telephone equipment and IP voice connections on this computer, as well as over the LAN - on servers running the corresponding service. Set to Manual.

System Event Notification– set to Auto for network computers, Manual or Disabled for home computers.

Remote Procedure Call (RPC)- as far as I know, this service must be set to Auto.

Application Management- finally the last service! By default it is set to Manual. Better not to change.

Well, everything seems to be ..., I hope everything will be fine after rebooting the system ... Once again I will warn you that if you are not sure, then it is better not to disable the service and then there should be no problems.
Good luck with setting up services and bug-free, after that, system operation!

Hello to all blog readers. Here we discuss which services
can be disabled without harming the system.

You can speed up the system and free up some memory by prohibiting the loading of unnecessary system services.
You can disable unnecessary services through :
Control Panel - Administrative Tools - Services
or Start - Run - services.msc.

Here you need to be extremely careful, because when you turn off all the services in a row, you can bring the system into an inoperable state and face such a situation that you cannot turn everything back on. In order to completely avoid problems when experimenting with services, it is advisable to, before performing these experiments,
save registry branch responsible for starting system services.
To do this, do the following:
Start - Run - regedit - OK.

What is here:
1. display name
2. process
3. dependent services
4. recommended value
Symbols designated * not installed in Windows XP Pro, they must be installed separately from the disk

Therefore, in order to get the maximum information about running programs and at the same time gain full control over them, you will have to take care of third-party task managers.

For example, I use a process control program AnvirTaskManager.
It gives out a lot of information on each program, but we are interested in
first of all what is displayed on the tab : Startup, Processes, Services(services), Microsoft Services, Non-Microsoft Services, Windows Services.
And there are displayed such useful things as: the command that launched the process - often the main role is played not so much by the executable file as by the command line argument;
path to executable file- this way you can detect viruses pretending to be legitimate programs; the process that started this program.
It is also important to identify left» software, such as processes running internet explorer, should attract more attention.
You can also check a suspicious file or process online using VirusTotal.

What services can be disabled in Windows 10 read

Good day. In this article, we will talk about what you can disable services in windows In most cases.

I have already told in order to increase the speed of this already nimble operating system at the moment.

Today I will tell you another way to improve this system with the help, as you understand, of disabling unnecessary services, and I will also give you a little theory about what these services are in general.

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 a computer, and some have system parameters and the OS will not be able to work without them.

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 computers. In general, there are

To view the list of services and generally control their work 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 startup parameters:

• Auto;
• Manually;
• Disabled.

With the help of these settings, we will make our system faster.

How to disable services and why?

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

If it was not started and the startup type was Manual, then you don’t need to change anything, or you can disable such services, but this makes little sense. Before moving on, it's worth understanding that each service usually has a description and you can accidentally turn off something wrong. I recommend that you carefully write down everything that you turn off and think three times why you do it.

So that later, if anything, it was possible, on the contrary, not to disable the services, but to enable them and return the computer to working capacity

List of services to disable

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

1. First of all, this SSDP Discovery Service" And " Generic PnP Device Node". They are needed when connecting "smart" household appliances to a computer and a number of universal devices. We have almost none of this in Russia yet;
2. Many probably never used the system error protocols and do not even know where they are located, not to mention why they are needed. Therefore, these services can be disabled. Namely: " Performance Logs and Alerts", "Error Logging Service" and "System Event Notification". They all write system errors to log files stored in the %SystemRoot%\SYSTEM32\WINS directory;
3. If you live at the 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";
4. If you do not have a Wi-Fi adapter for wireless Internet connection, then disable the "Wireless Setup" service;
5. If you do not use search through My Computer, or 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 with the built-in tools" Explorer"Will go much slower;
6. It is likely that your computer does not have a printer. In this case, you can disable the service " Print Manager";
7. Do you know what a scheduler is and use it? Not? Then disable the service of the same name "Scheduler";
8. If there is no local network (including a dedicated Internet line), then you can get rid of servicesg Telnet, NetMeeting Remote Desktop Sharin, "Remote Desktop Help Session Manager", "Network DDE Manager", "Security Account Manager", "NetBIOS over TCP/IP support module", "Computer Browser", "Sirens", "Workstation", "Server", " Exchange Folder Server", "Network logon", "Network DDE Service", "NLA Network Location Service", "Message service", "Cryptography Services", "Terminal Services", "Remote registry", "Background Intelligent Transfer Service";
9. Most likely you rarely use the services " Automatic update", "WMI Performance Adapter", "Smart Card Support Module", as well as "Smart cards" and " Portable media serial number". If this is so, or you do not know anything about them at all, then turn them off;
10. Do you have an uninterruptible power supply? If not, then disable the service" Uninterrupted power supply unit"

Perhaps everything. You can disable the rest at your discretion, once again - after reading the description of the service in advance. And writing down what exactly you are turning off.

Acceleration work is of interest to everyone. We are often asked the question: How speed up windows xp"?". To answer this question and tell everything we know about 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

While 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 consume valuable resources in vain, 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 use it. Acceleration operating system is achieved by disabling unused services.

Below is a list of rarely used services. Turning them off will not cause your computer to become unstable, but it may speed up windows xp.

DHCP client. With this service, a computer obtains an IP address by querying a DHCP server. In large companies where the staff cannot independently configure the connection to the network of work computers, this service is indispensable. At home, it is most often useless, 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 the DHCP server.

Remote Registry Service. Using this service, you can modify registry entries remotely (via a network). It has already been noted above that this service can pose a significant threat to the security of your computer.

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

QoS SRVP. QoS technology allows you to divide the network channel into bandwidths, but in most cases, the ADSL + splitter bundle at the hardware level successfully copes with this.

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, then it is better to disable this service, as it may pose a security risk to the OS. For the same reason, some unlicensed Windows discs do not have this service.

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, then 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 safely disabled.

time service Provides date and time synchronization for computers on the network. How much do you need your computer to ask the neighbors what time it is and rearrange their clocks?

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

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

Themes- provide functionality for all Windows themes other than Classic. Those. in fact, this service is responsible for rendering beautiful windows, smooth scrolling of lists, and other Windows XP beauties. If you are using a standard classic theme, then this service can be safely disabled. It is also worth noting that this is one of the most "gluttonous" services, the shutdown of which can noticeably speed up windows xp

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

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

As stated above, Windows XP acceleration 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 paging file

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

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 work. Windows. I would like to note that disabling these services will not affect the stability of the system in any way. I think the freed 150-200 MB of RAM will be useful to you for more necessary programs.

Click to open the Service Manager 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 key and select "Export"). In which case, 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 Remote Assistance capabilities. After stopping this service, Remote Assistance will not be available. Check the dependencies of the services in the Properties window on the Dependencies tab before stopping the service. It is recommended to disable this service as in idle mode, it takes up 3 to 4 MB of RAM. This service, if enabled and running, may slow down your computer a bit. This service, if enabled and running, reduces system security.

Error Reporting Service- Allows you to log errors for services and applications running in a non-standard environment. This service controls the system for collecting messages about unexpected system failures. The service consumes quite a lot 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, it can seriously slow down the speed of access to the hard drive. The operation of this service does not 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 performed. If this service is disabled, all services that explicitly depend on it will fail to start.
This service is required to access heterogeneous data sources within a single transaction. You can also find messages about disabling this service in the Event Log. In the future, this service may be required for .NET applications. If you are using Message Queuing or SQL Server, then this service must be enabled. This service, if enabled and running, may slow down your computer a bit. The operation of this service does not 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 manages 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 in and run programs, supports various TCP/IP Telnet clients, including computers running UNIX and Windows operating systems. If this service is stopped, then the remote user will not be able to run programs. If this service is disabled, any services that explicitly depend on it cannot be started. When this service is disabled, users will not have remote access to programs. This service, if enabled and running, may slow down your computer a bit. If this service is enabled and running, then the level of system security is significantly reduced.
