Drivers are the core of this issue. While most of the drivers functioned seamlessly before the upgrade, Windows 10 somehow corrupted them.

So, your first step is to try and roll back drivers to their previous state. In case that hasn’t changed anything, move on to the next step.

2. Use the SFC and DISM tools

1. Press Windows Key + X to open the Win + X menu. Now choose Command Prompt (Admin) from the list. If Command Prompt isn’t available, you can also use PowerShell (Admin).
   
2. When Command Prompt starts, enter sfc /scannow and press Enter.
   
3. SFC scan will now start and try to repair your system. This scan can take about 15 minutes, so don’t interfere with it.

If you keep getting error 0x800703f1, the issue might be caused by file corruption. This can occur for various reasons and cause your Windows installation to become corrupted. However, you can fix the corruption problems simply by running an SFC scan.

Once the scan is finished, check if the problem is resolved. If SFC scan didn’t fix the problem, or if you couldn’t start SFC scan at all, you might want to use DISM instead.

To use DISM to repair your computer, follow these steps:

1. Press Windows key + X and run Command Prompt (Admin).
2. Copy and paste the following command on the command line:
   • DISM.exe /Online /Cleanup-image /Restorehealth

   • DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
4. Be sure to replace ”C:RepairSourceWindows” path of your DVD or USB.

After the DISM scan is done, check if the error 0x800703f1 with 21h2 still persists. If the issue is still present, or if you couldn’t run DISM scan before, be sure to run it again and check if that solves the issue.
