3. Perform a clean boot

  1. Use the Windows + R shortcut using the Run dialog box. Type the following command in the text box and press the OK button. Msconfig error 1200

  5. Now, restart your PC as you normally do to access the clean boot state.

Now, follow the same procedure as before to sign into your Microsoft account. If the error 1200 does not present itself during the clean boot state, it means that third-party apps were restricting you from signing into the Microsoft account. You can now re-enable these processes one by one to identify the culprit. After that, uninstall the app to which the service is related.
