The previous issue only involved users running certain antivirus solutions, but this time it’s anyone. Or at least anyone who wants to restore their computer back to a point before the latest Windows 10 update was installed. Which is, let’s face it, a pretty common scenario considering the problematical nature of the update process.
Bleeping Computer was first to spot that Microsoft had updated a support document regarding system restore reboot problems. As long as you have system protection turned on in Windows 10 and have created a system restore point before applying the latest update, then you are at risk of being frozen out of your computer.

Microsoft confirms that under those circumstances the computer may experience “a Stop error (0xc000021a)” and when you restart the device “the system cannot return to the Windows desktop.” In other words, your computer is borked in a failed reboot scenario caused by the Windows 10 update that is meant to protect your system from potential harm.
