- Navigate to Advanced Options then click on Command Prompt
- Once Registry Editor is open ,go to the "HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status\ChildCompletion" and double click the setup.exe in the right pane. Change the value data from 1 to 3 and click OK to save changes.
- Close Registry Editor and restart your computer.
