This issue also affects users of Windows 10 version 1903.

Screen goes black, PC shuts down.

PC restarts, and goes straight to Desktop.

Latest cumulative update for Windows 10 fail to install, causes random restarts

I dont have a login or anything, and it doesnt go to BIOS either.

Theres no way to diagnose this as it is completely sudden and without warning.

100% a problem resulting from a recent Windows patch, one user noted.

I also started getting random unexpected restarts since going to 1903 this weekend.

Cant figure out whats happening, wrote another user.

Since 1903 my PC keeps randomly restarting.

Microsoft has yet to officially comment on these errors.

Its unclear how many devices are affected by the issue.
