I have a really old xp and the machine is going bad. I converted it vm and using vm player to run it. The problem is everytime I start the os its asking for a key and doesnt let me log in to the os itself. I have tried multiple VL keys directly from microsoft that the company have and it says invalid key. I looked on microsoft site and it says if time is incorrect the error happens. I logged into safe mode command prompt, and changed time. I am also able to use explorer command to log into safe mode but I cant do much on safe mode. Any help is appreciated.
