After waiting for months, I finally decided to just go with installing the latest Windows 10. I think I can work around one little problem. First of all, hide task view button from taskbar so I don't just go click it and freeze explorer.
Saw someone suggested using the start+tab shortcut for the task view menu thing, tried that but that freezes as well. Simple solution if it's frozen is to restart explorer: "Start+R" > "taskkill /f /im explorer.exe" and then "Start+R > explorer.exe" and I didn't have to restart windows.
Workaround for using virtual desktops: Use shortcut keys Ctrl+Start+D for a new desktop, Ctrl+Start+Left/Right arrow keys to navigate between virtual desktops and Ctrl+Start+F4 for closing a virtual desktop.
However, I have no clue on how to work around and still use the task view / window history feature.
I don't really need it anyway so, all okay for now. Everything else is working fine.
