I recently had to re-install Windows Vista Business edition on my PC due to a hard drive crash. A couple days after re-installing it, the activation wizzard popped up saying it could not activate my copy of Vista as the CD Key was already used. Well, I was the one who initially activated it on the same computer. The only things that have changed since the original install are: 1. replacement hard drive 2. upgraded RAM 3. upgraded CPU
How can I get my legitimate copy active again? Do I need to call Microsoft?
You should be able to activate over the phone. You can get started with phone activation by typing "slui.exe 4" in the search field in the Start Menu and pressing Enter. The phone activation process takes about 6 minutes.
