What do you all think about the Service Pack 3? I'm guessing this is relatively new now in Windows Update, but I can't seem to get it installed without failing everytime. Most recently, it started doing the backup stuff and trying to install, but failed on a couple of files and told me that it was completely installed and I may experience some problems with Windows. My computer has rebooted without my action twice in the last 2 days. Should I be concerned? I don't even think SP3 can be in my downloaded programs because it failed every time. So, I don't know that I could remove it. Any suggestions? Update: Surprisingly, there is a shell of the SP3 in add/remove programs with no data (doesn't tell me how big the program is). Safe to remove? I haven't been noticing that people are updating to SP3 - is it a necessity?
