Bought a used machine from a certified refurb co that had win7 home prem installed with COA(no media). I used Windows Easy Transfer to move files from older win7 pro pc to win home machine...but something went wrong.

After the transfer,the home machine rebooted,it had the win 7 pro settings & product key...which means the home machine won't validate and I can't reverse the WET info.

I had made some restore point but wouldn't restore prior to the file move.

Any suggestions?
