Hi Daton,
Welcome to Microsoft Community.
I'm Hahn and I'm here to help you with your concern.
Based on the information you provided, I understand that there were certain errors in the Windows Update process.
Could you let me know what kind of errors occurred during the update, knowing this information will help me better understand your situation.
You can first try the following methods to see if you can recover:
1. Clean boot
A clean boot starts Windows with a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update that may cause issues updating your PC.
Please refer to the following links for how to do this:
How to perform a clean boot in Windows - Microsoft Support
Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background program is interfering with your game or program and to isolate the cause of a problem.
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get you back on track.
2. Perform DISM and SFC scans
Search for “cmd” inside Windows search bar. Right click on command prompt and click on Run as administrator.
Type the following command and press Enter to run a full system scan to check the integrity of system components:
sfc /scannow
DISM is used when a sfc/scannow command is unable to repair corrupted or modified system files.
Dism /Online /Cleanup-Image /ScanHealth
This command will scan all system files and compare them with the official system files, scanning the computer for inconsistencies.
Dism /Online /Cleanup-Image /CheckHealth
This command must be used after the previous command has been executed and the system file is found to be corrupted.
DISM /Online /Cleanup-image /RestoreHealth
This command is to restore those different system files to the official system source files.
Reboot after completion and type the following command angin:
sfc /scannow
Check if the system files are repaired.
If neither of these methods can solve the problem, then the best thing to do is to perform a nondestructive repair.
3. Use the media creation tool to perform a repair upgrade of the system
Performing this can repair broken operating system files while preserving your personal files, settings and installed applications.
