Is the time running too fast or too slow on your Windows XP computer? If so it means the Windows Time Service which keeps your computer time accurate is broken and needs to be restarted. To restart the Windows Time Service you need get your hands dirty and enter some terminal commands at a command prompt. Even if you’ve never used the command prompt before don’t worry, because I will walk you through it with screen shots for every step (click images for full size).

1. Open a command prompt by clicking Start -> Run and typing “cmd” (without quotes) in the windows that appears, then click the OK button.


2. At the command prompt type “net stop w32time” (without quotes) and hit enter.

3. Now type “w32tm.exe /unregister” (without quotes) and hit enter.


4. Now type “w32tm.exe /register” (without quotes) and hit enter.


5. Finally type “net start w32time” (without quotes) and hit enter.

These four commands restart the windows time service so the time on your computer can run the time service at normal speed. If you get “The Follwing error occurred: Access is denied. (0×80070005)”Access is denied 0×80070005

then access to your system files is being protected, usually by anti virus software. First disable your ativirus software and if that does not help uninstall the software completely and restart, then w32tm.exe commands should start working.
