[vithusan_27]

So just recently I upgraded to windows 10, but now my computer lacks performance so I want to back to windows 7, but im the future say I want to go to windows 10 again can I do that or is only once I can upgrade to windows 10?

I believe you can re-upgrade to Windows 10 so long as you have reverted back to your previous OS within the 30 day grace-period, and as long as you re-upgrade within the full year the upgrade is free for eligible computers.
