Microsoft says that a known issue will block Windows 10 from booting after trying to restore the system to a restore point created before installing a Windows 10 update.

If the System restore is not working after Windows Update, then its because the update has changed the driver version on the computer. Here is the fix.

Windows 10 devices with system protection enabled and a system restore point created prior to the installation of one or more Windows 10 updates will no longer get their system started.

Microsoft has issued an update that System Restore may break Windows if you use it to revert to a version of Windows before said updates were installed.

Quick Machine Recovery (QMR) in Windows 11 is a resilience feature that uses cloud-based fixes to restore PC user access during a boot failure.
