I am trying to install service pack 2 on my PC. I am trying to download it directly from the windows update site, and when i attempt to "download and install" it says "preparing to install" and gets about halfway on the progress bar and says "failed!" I religously scan my computer for spyware and viruses, and everything else is fully updated, any ideas on what is going on? I need to figure it out soon, due to the fact that my college's network will only grant me temporary access for 35 minutes at a time. any ideas would be much appreciated! thanks!
