Hi Geez, thank you for the answer.
The key was already there and had the value 0.
I recreated it and DayZ is still crashing. :(

I am also getting the exact same thing, but I'm on Windows 7, I personally think someone might be messing with the servers? It's highly unlikely but I don't know. It even crashed in the menu screen.

I am also getting it in Arma 3 but only seems to happen in mulitplayer . I created the AllowAutoGameMode in my registry but it hasn't helped.

Hello everyone.
We have found out that some of the crashes you have been experiencing even on windows other than 10 were possibly related to an issue with BattlEye. There have been some changes on their side to possibly resolve the issue, can you try and let us know if you are still experiencing the crashes or if the frequency of the crashes has changed?
Regards,
Geez

I was able to play for like 10 minutes now before it crashed. After I restarted the game, it crashed again after 5 minutes with the same error.
I don't think that anything has changed.

So, is there something i can try to fix this issue?

Hello Creep.
Since the BattlEye fix did not fix the issue for you it is possible that it does occur due to the fall creators update. Would it be possible for you to try rolling back the update and let us know if you are still experiencing those crashes?

Geez

For some reason I cannot roll back to another version. I tried to rollback from the recovery options, it just tells me that i can't rollback.
Is there anything else I can try to rollback, or is a clean install to 1703 the only option for me to get rid of the creators update?

Hello Creep.
Is it possible for you to uninstall the update through the "Programs and Features" in windows? https://www.howtogeek.com/206271/how-to-roll-back-or-uninstall-a-problematic-windows-update/

I backed up my files on the hdd and reinstalled windows on the ssd.
I'm downloading the necessary programs, just need to know how to stop windows from downloading the Creators update?
It would be great if I could download security updates anyways.

You can stop the windows update by typing "services" in the search bar and right clicking "windows update">properties> then disable. I have been running into this issues and my pc is all up to date and what has fixed it be me is, in the same services window, disable everything that says xbox. Windows added some game changes for xbox that has issues with some steam games. The other thing to do is locate the dayz.exe file right click it and got to properties>compatibility>check the box that says "disable fullscreen optimizations". This is a 100% windows issue and windows needs to stop trying to dictate how they want us to play our games, the bad module is a windows issue with your gpu. Hope that helps you out and makes it so you can play.

I installed windows 10 Pro 1703 and everything seems to work fine now. :)
Thank you for the support @Geez and everyone else who tried to help me.
