I'm on SP2 and don't have any issues Are you 32 or 64 bit ?
You can always create a system restore point if anything goes badly wrong.
edit: I see in your sig you're 64 bit; there are no issues that I know of
Has been yes for ages.
Yep
Click Start (or the windows logo), right click on "Computer" and click "Properties"
Click "System protection" from the links on the left and then click "Create" in the "System Properties" dialogue box which shows (it'll show on the "System Protection" tab)
Basically gets vista to xp's level of reliability.
I wanted to phone ms to get a vista dvd with sp2 already on it, apparantly they dont accept debit cards???
It stopped my bluetooth dongle from working and I have not been able to obtain a driver since. It works perfectly in Windows 7.
