I reformatted just the other day. Once a year reformatting is not the worst idea in the world. I did it mostly because I wanted to make a clean WinXP install with SP2. Prior to that I made a CD disc from my copy of XP that has SP2 slipstreamed into it.
I used this program -SlipStreamer2Beta21- to do the slipstreaming operation. Making the new XP/SP2 CD bootable is a little tricky but not that hard. After installing my new XP/SP2 I was pleasantly surprised to find only 4 Windows updates were needed.
The major factor that keeps me away from Linux and with XP is the cleartype option
What's that?
