Notes for a Happier Computer and User:










Do NOT use "msconfig" to disable services, type "services.msc" in the Run box instead! Before disabling any service, check out the information about each starting on Page 13 of this document. Service settings are global, meaning changes apply to all users. All of these services are "Standard" with Windows XP. If you discover something other than these listed here running, another program installed them. A few of the more common processes are listed starting on page 41. Still unsure? Put your setting to "manual" or the listing under "Safe." Manual allows Windows XP to start the service when it needs to (or when ever it feels like it), but not at boot up. Depending on your configuration, not all services will start when required while in "Manual" mode. If you find you need a service, place it in Automatic. After adjusting your service settings, reboot your computer. If you do not have some of these services listed, do not panic! If your computer manufacture "pre-installed" your XP, they choose not to have certain services installed for you. This is, in most cases, a fact with OEM versions of Windows XP Home. If you find this document helpful and you wish to use this information (forums, web sites), please link to http://www.blkviper.com and do not copy or redistribute it. The online information is up to date and I do not want anyone posting old content. Disabling all of the "unneeded services" frees up 12-70 MB of RAM, depending on system. Do you mean that out of 89 services, 36 are set to Automatic as DEFAULT, but, we MAY only need 8 running?!? YES.

Table Header Information:














Display Name ~ is how it displays in the Services Control Panel. Service Name ~ is what the service's "short" name is and what displays in the registry. Process Name ~ name of the Process running in the background (displays in Task Manager by hitting Ctrl+Alt+Del). Dependencies ~ describe what other services this service needs to run. Default Home ~ this is what runs by default on Windows XP Home. Default Pro ~ this is what runs by default on Windows XP Professional. "SAFE" Configuration ~ this is the configuration that 95% of the people will be able to use with little or no side effects. It will also minimizes the amount of "errors" that is reported in the Event Viewer. This does NOT guarantee it will work for you, but if this scares you, this configuration would be a good starting point. Internet Gateway Configuration ~ setup to allow multiple computers on a network to share one access point using Microsoft's "Internet Connection Sharing and Personal Firewall" software. If you do not have this type of setup, compare the differences between "SAFE" and "GAMING" to find a middle ground that works for your system. Other software or hardware type firewall and gateway software may require a slightly different configuration. Gaming Configuration ~ this is the power user setup. This setup is a system that connects through a network (such as a gateway / router) to the internet, provides file and print sharing resources and gaming enjoyment. Some things MAY not function with this setup. No passwords save. Its use is not for a computer with analog modems or some direct DSL/cable connections. Try "Internet Gateway" Configuration first. Super Tweak Configuration ~ this is the Super Geek setup. This setup is a system that connects through a network (such as a gateway / router) to the internet with a static IP address. This system does not provide file and print sharing resources, nor have the ability to print. Its use is not for a computer with analog modems or many direct DSL/cable connections. You can use this configuration for extreme tweaking and testing purposes. Many things MAY not function with this setup. No passwords save. The Event Log may display "errors" of not being able to start certain services. CDRW functions may no longer work. Please do not ask, "How do I fix" questions while using this configuration. The answer will be "Use SAFE." This information's intention is for reference only. However, I use this configuration on a daily basis. Automatic ~ With a service in this state, it will start at boot time. Some services, when no longer required, will also automatically stop when not needed. However, this is very rare. If you find you do not need a service, place it into Manual or Disabled. Manual ~ Manual mode allows Windows to start a service when needed. However, very few services will start up when required in Manual mode. If you find you need a service, place it into Automatic. Disabled ~ This setting will stop a service from starting, even if needed. Errors in the Event Viewer will show up complaining of that fact. Some services, while Disabled, will constantly complain. However, this situation is taken care of if placed in Manual. The service descriptions identifies those that should be in Manual vice Disabled.

If you cannot modify your software installation of certain applications, put this service in to Automatic or Manual. If you have Windows XP Home Version, this service may be causing problems described in this knowledge base article: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q328213?SD=EE I have not tested this, but for now, Disable this service in Windows XP Home until installation of Service Pack 1.

You may choose to update manually due to the very long lag time from when an update is available and when Windows XP reports it. After the installation of Service Pack 1, you may configure how "often" updates are checked. Using default values, Windows XP "automatically" downloads the updates and asks to "install" them. A few reasons why you may think this is unacceptable in your situation: You could have a dial-up connection. If XP feels like downloading whenever it wants, it just may not allow you to do what "you" want. You may also: Wish to know what, when and how an update installs BEFORE using any bandwidth. Want to read about the update BEFORE downloading.

Want to know WHY you need it and WHAT it fixes.

It is very important that if you decide to disable this service, you check the Windows Update site often to ensure the latest patches install properly. Take note: Manual (and Automatic) updates via Windows Update web site requires Cryptographic Services to be running. Place both Automatic Updates and Cryptographic Services in to automatic if you do not wish to update manually. Default XP Home: Automatic Default XP Pro: Automatic Safe Setting: Automatic Log on as: Local System account Dependencies: What service Automatic Updates needs to function properly: None What other service require Automatic Updates to function properly: None Background Intelligent Transfer Service This service is used to transfer asynchronous data via http1.1 servers. According to Microsoft's site, Windows Update uses this "feature." It "continues" a download if you log off or shutdown the system (that is, when you log back in). The problem with that is, I do not like having this "feature" running all of the time. Even though I have found no side effects as to this being disabled, you may require this service for some MSN Explorer, Windows Messenger, Windows Media Player or future .NET functions. Take note: Manual update via Windows Update web site requires Cryptographic Services to be running.

ClipBook Used to store information (cut / paste) and share it with other computers. I have never found enough need for this to allow this service to always be running. This service alone uses about 1.3 MB of memory. Default XP Home: Manual Default XP Pro: Manual Safe Setting: Disabled Log on as: Local System account Dependencies: What services ClipBook needs to function properly: Network DDE o Network DDE DSDM What other service require ClipBook to function properly: None COM+ Event System You will receive, in the Event Log, an entry from "DCOM" complaining about not having this service running if disabled. I am unaware of any application that uses COM+, but if set to manual, many services report to it, so it will start anyway. This service is required for System Event Notification. For the fun of it: "C:\Program Files\ComPlus Applications\" On your system, see if you have any installed "COM+" Applications. If not, you can probably disable this service with no side effects (besides the Event Log complaining upon reboots). Take note: BootVis requires Task Scheduler and COM+ Event System to be running if you wish to take advantage of the "optimize system" function. Why is it required? It is due to the prefetching function built into Windows XP. Another Note: Pre-fetching only occurs on boot up and application start, so if you do not care about a few extra seconds of boot time, you may decide to not even bother with it and disable Task Scheduler. Depending on the system, pre-fetching may increase performance. Windows Media Player may also require this service for some "features" to function. MS' .NET may require this service in the future. I recommend disabled for Super Tweaking, automatic for "safe," and manual for most other configurations.

This service is not required on a standalone system. In fact, even if you want to browse the network (workgroup or domain) or have mapped network shares as local hard drives, you can still do so. On a large network, one computer is designated the "master" browser and another one is the "backup" browser. All others just announce they are available every 12 minutes to "take over" duties if one of the other computers fail. No lag time is discernable if this service remains disabled on all but one computer. Honestly, I do not even believe one needs to be running. You could, "just in case," but it sure does not need to be running on all computers, all of the time.

Always helpful to check out the Event Log to see what problems with applications are popping up that is "hidden" from the normal user. To see quickly what, if anything has resulted in your adjustments, you may consider clearing the Event Log. Windows Management Instrumentation also requires Event Log Service to be running. If you disable the Event Log Service, but do not disable Windows Management Instrumentation, your computer may have an extended boot time while Windows Management Instrumentation is waiting for the Event Log to start. It is just best to keep Event Log active for troubleshooting purposes and normal operations.

Indexing Service This service always has been a major resource hog. I NEVER recommend having this service enabled. Remove the function via the "Add / Remove Programs" icon in the control panel (Windows Setup Programs). It uses about 500 K to 2 MB in an idle state, not to mention the amount of memory and CPU resources it takes to INDEX the drives. I have had people (and witnessed it on other people's computers) report to me that the Indexing Service sometimes starts up EVEN while the system is NOT idle... as in the middle of a game.

To test for this security vulnerability, at the command prompt, (run: cmd.exe) type: net send 127.0.0.1 hi If you get a popup "hi" message, you should disable the Messenger service.

Protected Storage Allows for the saving of local passwords or even web sites information (AutoComplete). This service is set to Automatic by default. Due to security reasons, I recommend leaving this "feature" disabled to make things all that much more difficult to steal vital information if you do not "save" it. On the other hand, you may need this service to manage private keys for encryption purposes. If so, leave this service on automatic to ensure the "higher" security settings you choose work. If you disable this service, you will no longer have any of your passwords saved, no matter how many times you click the box.

Since my network is not straining under any load, this is rather pointless. You may require this service to be placed on Automatic if you use Windows Media Player or NetMeeting. Take note: Some people (as I did before I completed extensive research on this) reported that QoS uses 20% of your bandwidth and does not allow any activity, regardless. This is false. For more information, please view this KB article from Microsoft (I normally do not post links to them, but this warrants it): http://support.microsoft.com/default.aspx?scid=kb;EN-US;q316666 Regardless, if you uninstall the packet scheduler, no "bandwidth" is still reserved.
