The media creation tool allows you to create USB or DVD installation files so that you can install or reinstall Windows 10. Like anything, it sometimes freezes and displays “Check for Update” by a certain percentage. Here is what you need to know to fix it.
This is actually very simple: all you have to do is restart the Windows update process on your PC. Enter service in the Windows search box. Find the process named Windows Update and click Restart.
This will move the percentage (may keep moving). If it is not completed, repeat the above process until it is completed.
