System Hacks: Can’t restore Windows 10 after installing updates

If we encounter problems after installing Windows 10 update, we can use the System Restore feature to restore the system to the previous state. However, sometimes, when trying to restore the system after installing Windows 10 update, you will receive a restore stop error and cannot complete the Windows restore process. So, how to solve this situation when you encounter it?

1. Description of the phenomenon

According to the normal situation, after installing Windows 10 on our computer, we first open System Protection and then create a system restore point named “R1”. Then, after installing one or more Windows 10 updates and completing the installation of the updates, we restore the system to the “R1” restore point, which should work normally (Figure 1). However, the restore process encountered an unexpected stop and displayed a (0xC000021A) error and the system could not be restored to the “R1” restore point. I tried to restart the system, but could not return to the Windows desktop.

2. Cause Analysis

When Windows 10 prepares the files used in the system restore process, the information is saved to the Windows registry and the restore is completed at the next boot of the computer. In this particular case, Windows 10 loads the current driver before restoring, and if the process of loading the driver encounters driver mismatch and stop errors, then the restore process will stop and display the above error.

3. Problem resolution

Restore an unbootable system

If you cannot restore the system after installing the system update, you need to enter Windows 10 recovery environment to solve the problem. After several failed restarts, the system will automatically load the recovery environment. Select “Troubleshooting → Advanced Options → Startup Settings → Restart Now”. Afterwards, the list of boot options will be displayed, press F7 and select “Disable driver forced signature” (Figure 2). Afterwards, perform a restore and Windows should be able to resume the system restore process.

How to avoid this problem completely

In order to avoid the above problem that prevents you from restoring and booting properly, it is recommended to use the Windows 10 Recovery Environment to run System Restore instead of restoring directly in the Restore Settings window of Windows System Properties.

Press the Win+I key combination to open the Settings application and go to “Update and Security → Restore” (Figure 3).

Under “Advanced Startup”, select “Restart Now” (Figure 4). When Windows restarts, select “Troubleshooting → Advanced Options → System Restore”. Follow the instructions to select a system restore point and restore the system.

Tip: The above two ways to enter the recovery environment are different: the first one is a passive, automatic entry after repeated failed system reboots, while the latter method is a user-initiated operation to avoid problems.
