When you install, uncheck the box that allows Windows to automaticly activate.
This will allow you 30 days before you are required to activate. I allways install this way to make sure the OS is running stable, just in case I need to reinstall.
Hmmm, I'll have to remember this gem. I've had a couple of Windows installs that didn't go so well and needed a clean install to rectify the issues. Doesn't happen often... but it can happen, and I'd rather not be using up my activations on dud installs.
