I am using an older Windows XP computer, and I decided to transfer the hard drive to another computer. I contacted Microsoft And all I got was a non- helpful Indian dude. So I decide to revert back to my r=original PC, do some work, and call it a day (11PM), it's asking for a product key now, I was working on it 45 minutes ago, and this is urgent I need a computer to work. I had editing on there, all my files, I don t know what key it's talking about now because it was fine. So, how screwed am I because I don't know what I am going to be able to do about this without help. Thanks, sorry if this is very typed poorly, I am very stressed trying to solve all of this.
