MAKE WINDOWS XP BEHAVE

• Make disk images, restore points, and backups of files and registry keys to repair your system if you fuck things up.
 
SERVICES
 
  • Optimise XP Services settings  
 
Windows Services are applications that run independent of user accounts: they keep running even when there's no user is logged into a user account.
Startup of services can be Automatic, Manual, or Disabled. Some services don't start when needed in Manual mode.
Services which are always on are best started automatically to reduce boot time.

To set up services for faster booting and reduced use of memory and processor power:

1) Run services.msc

2) Change all running services to Manual (except Plug and Play, Remote Procedure Call, Shell Hardware Detection, Windows Audio, Windows Management Instrumentation, and Workstation, or your system may become unbootable).

3) Unplug all USB and other Plug&Play devices, including your DSL or cable modem, CD/DVD burner etc.

4) Reboot. It takes longer than usual because Windows tries to find out which services it needs.

5) Go back into Services (before you use any other apps) and change the active services to Automatic.

6) Reboot. It should go faster now.

7) If you always connect to the internet at bootup (cable, DSL), plug in your modem, reboot, go into Services, and make sure all running services are set to Automatic.

8) Review the list below and set unwanted services to Disabled, and those you need to Manual or Automatic.

Old 16-bit programs fire up wowexec.exe (windows on windows) and/or ntvdm.exe (windows 16-bit virtual machine).

Warning: wowexec.exe keeps running after you close the 16-bit program and can eat lots of memory, so close it when it is no longer needed. Do NOT close it while the 16-bit app is still running or it will crash.

Many programs run their own services. Details on www.blackviper.com/WinXP/strangeservice.htm
