All my [censored] Windows 7 upgraded and activated

Uh? Did you use rollback? Or fresh install? Have you gone through phone activation?
You're correct. The offer period is 1 year. Once you have upgraded to w10, it's yours. I'm not sure how others intepreted it as 1-year license validity.
Yeah my best guess is that the current driver was partially compatible. I believe asus will release one later.
Actually most of the 'bugs' that happened were due to new drivers or updates haven't been applied imo. I don't find anything weird yet after it's fully patched.

Well no it's not about high end or not. we have a user upgraded his 7-year-old laptop without glitches too haha

then how did u activate ur pirated win 7 ? windows 7 didn't ask for activation code?
