A new bug affects a recent Windows 10 update and may prevent the system from restarting normally

We have always recommended keeping our devices updated with the latest versions of _firmware_ released by manufacturers. It is a way to be protected against possible threats and security breaches. The problem comes when those updates also cause failures.

In the case of Windows, the problem is that it is something that is being repeated too dangerously. Something that is happening again with one of the latest updates released by the company and that causes the affected computers to restart normally

The computer cannot be restarted

Microsoft are working to avoid potential problems during updates, but so far it seems they haven't achieved what they want. This is now an issue that is reported any time the computer needs to be restarted.

If your computer requires a reboot after, for example, installing an update or reverting to a recovery point, you may encounter this unforeseenAnd for now it does not seem that the failure is due to the interference of any antimalware system or a specific antivirus.

In fact, from Microsoft they already seem to be aware and warn that this failure prevents returning to a restore point that we have established or if the PC requires a restart to solve a problem. This is a stop error (0xc000021a).

"

Microsoft acknowledges the error on its support page and warns that after generating the error and given the impossibility of restarting, the computer enters Windows Recovery ModeA process similar to the one we saw a few days ago is then started if we wanted to change a forgotten password in Windows 7."

"Within the "Troubleshooting" menu we must look for "Advanced options" and then the "More recovery options" and "Startup settings" section to finish with "Restart now". At this point it is important to make sure that the Disable driver signature enforcement option is disabled, for which Microsoft advises that we must use the F7 key."
