Since WinUpdate LFS minimized randomly

[Brixton]

Hey folks,

a few days ago I run the last WinUpdates.

I have now Build 17134 and the Creators Update. Before I haven´t.

Since them my LFS (maybe other games, dont know have no others games atm installed) just randomly minimize.

I took every notifications off. The contacts and the contact notifications are disabled too.

Avast is in quiet mode (no notifications).

Problem is. When it jumps to the desktop, I see only the desktop when I have no other programm (e.g. browser) running. So I can´t see which programm get in the foreground.

I know from talking on server yesterday, that some other user have same issues. Someone have another idea for a solution?
