1. Open the File Explorer
2. Go to the path C:\$GetCurrent.

4. In that case, go to the View tab and check the box associated with Hidden items.
5. In this folder, you will find the Media folder.
6. Copy and paste it to the Desktop.
7. Restart your computer.
8. Now, copy the Media folder back from the Desktop to the C:\$GetCurrent folder
9. Open the Media folder and double-click Setup.

Follow the on-screen instructions to finish upgrading

This way, you will be able to reset the process without deleting the Media folder. So, try running the Windows Update assistant once again.

3] Run the Windows Updates Troubleshooter
