I got a new laptop and one of the first things I did was install Windows 10. My colleague has more or less the same laptop and complains how slow it is.
My Microsoft surface pro 8 is a slow piece of shit now. The animation switching between virtual desktops stutters. Any time I do it, the task bar goes blank and the height of it increases a lot before reverting. No I'm not reinstalling it. Talk about a waste of productivity. 10 is not great, but in modern terms it's the new 7.
My gaming machine has 10 for some select games everything else is done on Linux - even a majority of my gaming.
