Windows 10: Laggy Games

So, I recently got a new computer, and it's been working fine ever since I got it. Suddenly, my games lagged to the point they were barely playable. And it's ONLY my games. Everything else works fine. Does anyone know how to fix this?

Microsoft Games Very Laggy

Sorry it to so long for the reply, I lost my charger and had to get a new one. I've tried both sets of steps, and it's still exceptionally laggy. There's a 1-2 second delay between when I touch the screen and when something moves. It's happening in
other Microsoft games, too.

 

Microsoft Games Very Laggy

Recently the Treasure Hunt game has become extremely laggy. I will click on a spot and it will take 2-3 seconds before the character moves to it. It's not the internet connection, because it happens both at school and at home. I can't try it on other
Windows 10 devices because everything else I have is Windows 7 (and no, I'm not upgrading them just to test a game lol). Has anyone else encountered this and if so what did you do to fix it?

::Edited:: Just tried playing the Solitaire game collection, and yup, it's laggy as all heck, too. What is going on??

 

old games are so laggy after windows 10 update

For me the same problem. All drivers and additional updates are ready, but still the game is so laggy
