Here's the issue: I purchased a new HP laptop for nearly two (2) years now , with Windows Vista Home Premium pre-installed. but yesterday, I am prompted to give product key
for activating windows. The one I type in is on the back of my laptop, with a side notation of "Proof of License Certificate of Authenticity MICROSOFT". However, the product key doesn't seem to work as I keep receiving an error message indicating
"The key is incorrect.
pls, how do i solve this. and why i am asked for produck key now. whereas, i used the computer yesterday
