I've recently learned about the security risks related to kernel-level anti-cheat software used by some of my favorite games on Windows 11. There seems to be a lot of debate about how serious the threat really is. For example, I've heard claims that once kernel access is granted, the software can dig in so deep that even uninstalling it might not fix the security issues. Is this true? What steps should I take now and in the future to protect my system while still enjoying gaming?

I recommend not playing games with kernel-level anti-cheat altogether if you're worried about security. It's a personal choice, but it’s something I’ve avoided entirely. And just so you know, my setup is all-Linux, which could be a different approach for you, but I understand that might not apply.
If you're concerned about trust, then just don't install the software if you don't feel comfortable with the publisher's track record. The risk of something burrowing in is there but pretty unlikely; it's similar to the risks of installing any driver.
If you’re running separate Windows installations on different SSDs, here are a few thoughts:
1. If your current OS is encrypted, it remains that way.
2. For safety, yes, use the second drive just for these games; it can help protect your other data.
3. If you face kernel issues on the second drive, your system will be at risk when using it.
4. Personally, I avoid these types of games, but if you must play, consider minimizing personal info on that installation.
Yes, it's true that once something has kernel access, it's effectively part of your operating system. The most reliable way to remove it would be to format your drive and reinstall everything from scratch. So, you should really consider if a game is worth that level of access on your PC.
Thanks for confirming that! I don't usually think game developers are malicious, but I worry about vulnerabilities, especially if the software can be hacked.
How can someone tell if a game or software installs kernel-level components?
Appreciate the advice! It's a tough balance between enjoying gaming and keeping the system safe.
