I haven't done it yet..........kinda dragging my feet because it's going to be such a hassle to reconfigure the machine after reinstalling. I'll probably do it sometime very soon.
Any advice you can give me on formatting the C: drive prior to installation would be great.
Hey! Sure, you can do it whenever you want. On the formatting thing: keep in mind that by formatting, Windows CANNOT find a license anymore. You lose your data too, so if you can't move your installation, I wouldn't recommend. When you are reinstalling Windows, either from the system, making an update or just installing it from USB/DVD/CD-ROM, it creates a windows.old folder where it moves all your C: drive. It can be located in C:\Windows.old. So, to be honest, I wouldn't format the drive :)
