A customer laptops in my friends computer shop had some major issues today. One of the major issues on this Windows XP laptop was the fact that Service Pack 3 would not install so after fixing various other things I figured it would be best to clear the Windows Updates cache and then attempt to install the patches including SP3 again. Below is information on stopping the Windows Updates service, purging the Windows Updates cache, and then restarting the Windows Updates service.
How To Clear Windows Update Cache:
- Open Command Prompt: First on your Windows computer click the start icon in the taskbar and type “cmd” in the search box to launch the Windows Command Prompt.
- Stop Automatic Updates Service: In the Windows Command Prompt window type the below text and hit the enter key to execute stopping the Automatic Windows Updates service.
- net stop wuauserv
- Change Directory: After stopping the Windows Automatic Updates service you should “cd” into the Windows directory using the syntax below.
- cd /d %windir%
- Purge Automatic Updates Cache: Now from the Windows directory issue the below command to purge the Windows Automatic Updates cache.
- rd /s SoftwareDistribution
- Start Automatic Updates Service: Clearing the Windows Automatic Updates cache may take a little while but once it is completed you should start the Automatic Updates service again using the syntax below.
- net start wuauserv
- Update Windows: After you have purged the Automatic Updates cache and restarted the Automatic Updates service you can attempt to manually install the updates again by visiting the Windows Updates site located here.
If one of the files in the Automatic Updates cache was causing you a problem you should now be able to update your copy of Windows either via the Automatic Updates or by visiting the site in step 6.
