Step 8: After the command executes, restart your computer and try running the Media Creation Tool again.

Method 4: Perform a Clean Boot

Note: Performing a clean boot will not erase any data on your system.

Step 1: Press Windows + R to open the Run dialog, type msconfig, and press Enter.

Step 2: In the 'General' tab of the System Configuration window, select 'Selective startup', uncheck 'Load startup items', and ensure 'Load system services' is checked.

Step 4: Click 'Apply' and then 'OK'. Restart your computer when prompted.

Step 5: After restarting, try running the Media Creation Tool. If the error is resolved, a third-party service was likely causing the issue. You can enable services one at a time to identify the problematic one.

Method 5: Run the Media Creation Tool as Administrator

Running the Media Creation Tool with administrative privileges can sometimes bypass permission issues that cause the error.

Step 1: Locate the MediaCreationTool.exe file on your computer.

Step 2: Right-click on the file and select 'Run as administrator'.

Step 3: When prompted by UAC, click 'Yes' to grant administrative permissions.

Step 4: Attempt to use the Media Creation Tool again to see if the error persists.

By following these methods, you should be able to resolve the error code 0x80072f8f - 0x20000 and successfully use the Windows Media Creation Tool on your Windows 11 PC.
