my PC runs fantastic. its a Toshiba satellite l675 with 4 gigs of ram and a i3 processor. Had it for a year with absolutely no problems. And when I check Windows Update I have 69 Important Updates and 21 Optional Ones. I know the Optional ones are not that critical, but if my PC has been working just magnificently well for the last 12 months, should I even bother? There is one Silver light Update that I would consider. 4 For Office, 1 for Windows Defender, 1 from Visual Studio 2008 and 61 for Windows 7. I only install programs, drivers, updates that I really need. I believe in the saying, "If its not broken, don't fix it." What do you think? Thanks in advanced.
