Run Prompt


It should open “Registry Editor”, now do following steps:

Go to the following registry key:
“HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL”

You will find tree type navigation on left side pane, click on the + sign on text mention on above path means first click on + sign of “HKEY_LOCAL_MACHINE” then on “SOFTWARE” then on “Microsoft” and so on until you find values provided in below screen shot.

Note: If you are a newbie then I would suggest you to back old entries before you make changes. To backup registry simply right click on “SHOWALL” name on left side then click “Export”, give a suitable name and save.



You only need to change or check two registry keys.

1. “CheckedValue” value should be 1.

2. “DefaultValue” value should be 2.

Don’t close “Registry Editor” now, go to folder option and try to unhide files and folders. It should work now and you can close registry editor
