How to deal OS issue
I have a laptop and its OS is Windows XP Home Edition. I changed the OS by the help of the technician.
He changed it to Window XP Professional.
I was trying to use my laptop with the new software, but an update suddenly appeared which says "you may be a victim of software counterfeiting".
So I wanted to change again my OS to the original OS I had.
How do I deal this issue?
How would I change the OS again?
