i am getting alt tabbed out of games

I formatted my laptop which is an Alienware 17 r5 on October 2019 and I put windows 10 build 2004. I put nvidia driver version 456.71, I installed steam, I installed Bitdefender internet security and focus assist in windows was enabled. Everything was ok and I never got alt tabbed out of games automatically

I was playing a ps1 game on a ps1 emulator and I was playing death stranding on February 2021. I used a game trainer when I played death stranding and I enabled the enemies can't attack option. Things were okay when enemies detected me and nothing happened

I put nvidia driver version 461.72 on February 26 and after that the alt tab problem started

First I got alt tabbed out of death stranding and the focus jumped to a windows explorer folder which was opened in the background. The issue was not random and it only happened when a certain enemy detected me and the enemy can't attack option was enabled in the trainer and it didn't happen when the enemy can't attack option was disabled

Also when I was playing the ps1 game it froze for like 20 seconds when I moved the character to a new screen and then I got alt tabbed out of the game and the focus jumped to a windows explorer folder which was opened in the background and then game unfroze. The issue only happened once

Next I played just cause 3 and I frequently used to get alt tabbed out of the game and the focus jumped to a windows explorer folder which was opened in the background. Also the game became a bit choppy when I alt tabbed back into the game so I had to exit the game and run it again and it stopped being choppy when I restarted the game

After that I played a few old games and I didn't get alt tabbed out of the games and then I started playing trails of cold steel 4. I played the game for 5 days and all was ok and then the game froze for a bit and then I got alt tabbed out of the game and the focus jumped to a windows explorer folder which was opened in the background

Also sometimes steam is becoming unresponsive and I have to kill the the task for it in the task manager. This happened a couple of times recently and the last time it happened was when I got alt tabbed out trails of cold steel 4. I quit the game and I saw that steam was unresponsive

What is happening to me and why is the focus always jumping to a windows explorer folder when the alt tab happens? If explorer.exe is stealing focus then that means that I could have shell extension which is misbehaving but that's unlikely because my only shell extensions are the winrar options and the scan with Bitdefender option

The only logical explanation is that the new nvidia driver that I put is causing the problem. The problems started after I put nvidia driver version 456.71 and I was using that version for the whole time. Can the nvidia driver make games alt tab by themselves?

I don't think nvidia graphics driver causes "alt tab" during gaming. What ps1 emulator you use ?
Did you try if this "alt tab" issue happen on pc game ?

i think i discovered the issue. i have steam installed on my laptop

in the past 2 months i am noticing that the steam chat window is freezing and becoming unresponsive so i have to kill the task steam client webhelper in the task manager and that will close the steam chat window and then i am exiting steam and restarting it. the steam chat window is freezing because the task steam client webhelper is misbehaving. the problem is new and it started after a recent steam update. if i am playing a game when the steam client webhelper misbehaves then i am getting alt tabbed out of the game

if i manually alt tab out of a game then the game stops running and something else shows on the screen

when the alt tab is happens on its own when i am playing games and the game is still running in the background and i can control it but there is something else showing on top of the game

today i was playing a game and chatting on steam. the steam chat window was showing on the screen then i went back to the game. after that it did alt tab on its own and it went back to the steam chat window and the game was still running under the steam chat window and i could control the game. i quit the game and then i noticed that the steam chat window was frozen and it became unresponsive

i uninstalled steam and i deleted all the left over files. later on i will reinstall steam. i want to know how can i make the process steam client webhelper behave and not cause me problems. what do i do?

Since you found out the cause of "alt tab' issue is steam, don't use. I don't use steam. And i unload any programs for
best performance gaming.
