Windows XP: Clear Windows Update Cache, Purge Windows Updates Cache
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.
