How to Fix ERROR_LOCAL_USER_BX06DE4897_MD9858 Pop-Up on Windows?

Issue: Hey, I have a problem with my computer, namely, I cannot log into it. I downloaded a game and installed it, and my PC froze. After a restart I was faced with a Blue Screen error, saying that my Windows Product key expired and that I need to come tech support via the number +1-844-459-882. However, I checked and this phone does not match the one provided on the official website, so I suspect it's a scam. The problem is, I cannot use my PC since it is not loading, apart from the message. Is there any way to fix ERROR_LOCAL_USER_BX06DE4897_MD9858? Please help me!

Solved Answer

ERROR_LOCAL_USER_BX06DE4897_MD9858 is a fake message and a Tech Support scam[1] that appears on your PC after it gets infected with a specific type of malware called screen-locker.[2] It claims that you need to verify the Windows Product key and enter it into the box or call a fake Windows support number.

The scheme is relatively simple: cybercriminals create malware and infect victims with it. The main goal of the ERROR_LOCAL_USER_BX06DE4897_MD9858 scam is to make users believe that something is wrong and the fake alert authors are real technicians willing to help.

By merely looking at the message itself, you can instantly see signs of deception: grammar errors, as well as certain words, are not written in a manner an official Windows message would show it.[3] By any means, Microsoft would never show a contact number on error messages – error code is displayed instead.
