There is friend who is getting the "Your installation of XP is not genuine" message from some weeks. So I told them to ignore the message and download the XP Product key update tool from the below link and follow the method on how to install a new product key:
After they did that, the program did not give any error message but it asked the system to restart. After booting the XP product activation service came up and asked them if they wanted to register and validate or just validate the system but that didnt work. It gave the below message:
- Activation period has expired
Does anyone know how to solve this issue? Thanks.
