Before making any changes to the registry database, it is recommended that you back it up so that you can restore the registry if necessary. Open the Run window with Windows+R, type: Regedit, and click OK. Answer Yes to the question about the administration of user accounts. After right-clicking on the Computer entry, select Export from the local menu. This will open a new window where you will be asked to enter the name and location of the backup, and finally, click Save to perform the operation.
