Win10 lock screen on blue? 3 steps to get

Recently, I helped someone fix the issue with Caton, and another user mentioned that pressing Win+L to lock the Windows 10 screen often caused a restart without a direct blue screen. I've also encountered this problem before, and after some research, I found out the root causes. Let me walk you through them one by one.

To start, open the Command Prompt as an administrator and run the following commands:

If exist "%SystemRoot%\System32\InputMethod\CHS\ChsIME.exe" (

Takeown /f "%SystemRoot%\System32\InputMethod\CHS\ChsIME.exe" /A

Icacls "%SystemRoot%\System32\InputMethod\CHS\ChsIME.exe" /deny "NT AUTHORITY\SYSTEM:RX"

)

This command helps reset the system files responsible for the lock screen and wake-up functions in Windows 10.

Additionally, if you experience a blue screen when using music software while the screen is locked, it's likely due to Windows 10's background management system. By default, only UWP apps can run smoothly in the locked state, while traditional .exe (Win32) applications are suspended or frozen. However, music software may force the system to keep playing, leading to conflicts. This can result in a blue screen crash.

To avoid this, either close or pause your music software before locking the screen, or switch to a UWP app like Groove, which comes pre-installed with Windows 10. For now, this is the best workaround. Whether Microsoft will fix this issue in the future depends on their plans.

Moreover, drivers related to multi-memory mixing or SSD/M.2 SSDs might also cause issues like blue screens during the lock screen. Make sure your drivers are up to date and compatible with your system configuration.
