You'll need some technical skills, like knowing how to:

* Burn an ISO file to make an install DVD
(A good example of what we mean by “technical”)
* Install Windows (of course)
* Backup and restore your PC
(There's a chance of losing files, so it's a good idea to do
a backup of anything you want to save.)
* Set up a network
