win10 > win8.1 > win8 > win7

win10 and win8.1 not very much performance improve but still i do notice it still better in some degree.

and ts your pc no problem, can win10.

but i want to remind you, the best option is to clean install windows. windows install from "upgrade windows" no matter from ? version to ? version of windows are always the same, lag and slow, defragment can't help much.

unless the windows before upgrade are very well optimized.

but most of user don't know how to optimize their windows.

if ts are tech guy then he wouldn't open this thread, since he open this thread mean he's not a tech guy. so I assume his windows are not optimized one.
