The latest Windows security update locks users out of their PCs – This is something you definitely need to pay attention to

Microsoft has released a new security update for Windows 10 and Windows 11 . However, some users are complaining that they can no longer log in.

Microsoft regularly brings updates for its Windows operating system. However, not everything always goes smoothly. There are regularly updates that can even ruin your gaming performance under Windows 10/11.

What has happened now? According to the online magazine The Register, users who have downloaded the latest update for Windows are experiencing some issues. It can even happen that they are locked out of their PC after a restart.

The latest update prevents some users from logging in

What kind of update is this? The update for Windows 11 designated KB5012170 addresses security vulnerabilities that could allow unauthorized code to be executed during the boot process. Since most Windows computers now rely on UEFI, the update is very important.

UEFI stands for Unified Extensible Firmware Interface. It is the successor to the BIOS and ensures that your operating system can be loaded on your PC.

The update KB5012170 is causing some users to be unable to start their PCs. After installing the update and subsequently restarting the PC, some users are prompted to enter their BitLocker key to regain access to their computer.

However, the problem only occurs if you or your employer had BitLocker set up on your PC. If you have never used BitLocker, you should not experience any issues.

What exactly is the problem? The frustrating part is that you need to enter a specific recovery key if you want access to your data again. You cannot start your system, nor can you access your pictures, games, or other stuff in any other way.

In the most frustrating case, you do not have your BitLocker key at hand, or you may not even know what kind of recovery key is needed.

If you are still unsure whether Windows 11 is worth it for you, check out our checklist:
