Windows 10: Alt-Tab is very laggy

For the last few months, my alt-tab quick switch (when you just hit alt tab) has been very laggy. Couldn't find an answer on the forums. Tried turning off focus assist but nothing works. It even happens when light programs are opened and I don't really play games so that's not the case.

alt + tab not working

Just found a really cool way to make alt+tab INSTANT!!!

In the launch options write the following: -windowed -noborder





This play exactly the same as fullscreen but now you dont have to wait 30 f*@!ing seconds to alt+tab back in!

Also you don't get the little purple/black checkered effect (only in Source games) from alt+tabbing in fullscreen.

 

alt + tab not working

*Confused I can alt tab back even if i don't have another program to switch too.
