Hi, moreover, when one click the windows repair, there is an warning of creating restore point. Have you created it. If it has been created, go to the system restore to restore the system to a previous date, by choosing the restore point. It is very safer tool. It does not harm the m
computer. Even though it is running on the background, the check is always safe. Creation of restore point is one of the main option in the menu. It also gives you option of other pre checks before using windows registry tool. I am using, whenever i have problem. You could select that part of the option, where there is a problem.
