Posted in: Windows 7 , , , No Comments

Problem: You have hidden some folders in windows 7. But now you cannot unhide the hidden folder. Hide option is disabled in folder properties.

Cause: Some virus on your computer have modified default registry value for folders.


  • Click Start button and then type regedit in the Start Search box. In the search results list, left click regedit to start windows registry manager.
  • Navigate to:
    HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced \ Folder \ Hidden \ SHOWALL
  • Double Click CheckedValue and enter 1 in the value data box.
  • If there is no CheckedValue, right click in the empty area, and create a new DWORD (32 bit).

    Rename this value as CheckedValue and set its value to 1

You may need to restart your computer. You should now be able to un-hide hidden folders.

Note: Your computer may still have some virus which can again change registry value. So, perform a full system scan with a good and updated antivirus.
