 Q.3. So what will happen when pirated Windows users are unable to activate their Windows 10 versions?

Ans. It'll work like a trial version of Windows 10. You'll get a limited period of time e.g. 30 days to use Windows 10 and to activate it. If you don't activate Windows 10 within that grace period, you'll be unable to use it further and you'll not be able to log into Windows 10.

Also a watermark on Desktop will become visible telling you that you are using a pirated Windows version and you should make it genuine by activating it using a genuine license key.
