Computer Clock Running Too Fast or Too Slow?

Is the time running too fast or too slow on your Windows XP computer? If so there’s a good chance the Windows Time Service (which keeps your computer time accurate) is broken. Fixing it is just a matter of restarting the service but you need to get your hands dirty and enter some terminal commands. (click images for full size).
1. Open a command prompt by clicking Start -> Run and typing “cmd” and click the OK button.
2. At the command prompt type “net stop w32time” and hit enter.
3. Now type “w32tm.exe /unregister” and hit enter.
4. Now type “w32tm.exe /register” and hit enter.
5. Finally type “net start w32time” and hit enter.
If you get “The Follwing error occurred: Access is denied. (0×80070005)”
then access to your system files is being protected, often by firewall or 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.

Thanks for the info. My clock sometimes runs about 15 minutes fast for no reason. Might be the CMOS battery, but I’d rather try this first.

Thank you! I have tried many things and this was the only solution that WORKED!

I was told it was CMOS battery by Microsoft over the phone, but I tried your fix and it is working! Thanks so much!

I had such high hopes for this fix. Ran it three times – clock jumped ahead while I was running it the first two times. It just jumped ahead again, now. Bummer.
