Windows 7 want to change color scheme after starting fortnite?

Recently Windows changed automatically as soon as I started fortnite, you asked me the color scheme a few days ago, now it simply changes it, I have already reinstalled it and it says it is not compatible, but what is compatible then.

See the screenshot

thank you

The problem will probably be the (by the way memory and graphics intensive) window transparency of the aero design, which nobody really needs anyway. Since that has existed, I have given it up.

Say what should I do now?

Refrain from using it.

Fortnite or the color scheme?

The color scheme, of course.

It's been today I've been playing Fortnite for 2 years without a problem and for a few days windows wanted to change it, but I refused and now it does it automatically

I have a gtx 960 and intel i 5 and play on my graphics with 140 fps without drops, that really can't be, do i have at least more fps now? Xd

Then something has changed either in the graphics and memory requirements of Fortnite or in the Windows settings for your graphics card.
