Beware of Pranks: Activating Windows 10/11 with This Key Could Lead to Endless Crashes and a Mandatory Reinstall

While iOS devices sometimes encounter peculiar bugs that can crash the system, such issues are rare on Windows—especially crashes triggered by activation keys.

Recently, a user on X/Twitter shared an activation key for Windows 10/11 that looks no different from a legitimate key at face value. However, attempting to use this key for system activation can cause the system to crash, leaving no option but to reinstall.

Here at Landian.news, we remind you to be cautious when searching for activation keys online. Falling for such a trap can lead to system crashes, forcing you to spend valuable time transferring data and reinstalling your OS.

For Educational and Research Purposes Only - Do Not Misuse:

Activation Key: BFXT4-MY2GY-MBCRK-PBN7B-HT963

Test Environment: It's recommended to conduct tests in a virtual machine running Windows 10/11 Home or Pro. If testing on a physical machine, ensure you have backed up your data beforehand.

Testing Method: Start Windows 10/11 normally and proceed to activation. Enter the provided key and follow the on-screen prompts. After entering the key, the system will verify it and prompt a restart to complete the activation process.

Outcome: After restarting, the system will crash repeatedly. The error code, MUI_NO_VALID_SYSTEM_LANGUAGE, suggests a possible issue with the language pack. However, this seems to be a bug since a failure in adding a language pack shouldn't cause continuous system crashes.

Additional Information: This key might target specific editions, like the CCS or Home China versions, leading to language pack issues and system reboots on those editions. However, Microsoft could potentially resolve this by rejecting the key upon verification.

If You Encounter This Issue:

Currently, there's no way to repair the system after such a crash. The only solution is to remove the hard drive and attempt data recovery on another machine. This highlights the importance of regular data backups.

If you've been using your system for a while and have accumulated significant data, falling victim to this prank could mean a complete system crash and the necessity to reinstall everything. Managing to salvage any data would be a small miracle.

Why this key causes endless crashes remains under investigation by Microsoft. Given the nature of activation keys, even if an inquiry is made, the results might not be publicly disclosed. At most, Microsoft could fix the bug or invalidate the key to prevent further misuse.
