it is too common nowadays, using microsoft windows as operating system, virus comes in so much way. Through internet, thumbdrive, etc. And they usually disable all the special tools such as Registry Editor (RegEdit.exe), Task Manager , and Folder Option.
How to enable them back?
Well, you can follow this steps. :)
1. If you still can access your registry editor, then open up the registry editor by click on start menu, then hit run. Then type regedit. If you are doing right, then a Registry Editor window will pop up.
