Games randomly minimising on windows 10

[Tomahawk]

For the last couple of days when i've been playing games in full screen they've been minimising without me doing anything (annoyingly during ranked matches on tekken!). I've noticed a window opening up and closing again instantly. I have no idea what it is but I think it might be the cause. If anyone can help fix this problem it would be appreciated.

I had this happening a while ago too. Something in the Microsoft Office directory (I believe it was Office15) in C:\Program Files (NOT Program Files (x86) ) kept minimizing games. So I just deleted the .exe file (seeing as I don't use Office and don't care if it broke) and it stopped.

I found this: https://www.lifewire.com/how-to-prevent-programs-from-stealing-focus-in-windows-2624453
which explained a lot.

I used:

to find which file was misbehaving.

I have no idea how much tech experience you have so if you need any help with the app, let me know. Hope it helps.

This is the quick fix for the issue, no need to download anything.

Keep in mind that disabling this might stop office from updating itself so try checking for an update manually later on when they fix this. Office should be updated because of security fixes and that stuff.

Ive disabled the updates so hopefully that's solved it. Thanks for the help guys
