Which key is genuine and useful!
When I purchased Toshiba Laptop with windows 7 Home Premium, It came to me preactivated with SLP key.
There was also a key with COA sticker.
Now I have converted Home Premium to Ultimate with windows Anytime Upgrade key.
That means I have three keys. In case of reinstall which one to use? I am in a dillema!!!
Can someone please clarify?
