Problem with Show Hidden Files & Folders

Fixing "Show Hidden Files & Folder" Problem

1. Go to the following registry key: (go to Start >> Run >> type “regedit” and then press “ok”)
2. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
3. DELETE the value CheckedValue in the right window. (Its type should be REG_SZ and data should be 2.)
4. Now create a new DWORD value called CheckedValue (same as above, except that the type is REG_DWORD).
5. Modify the value data to 1 (0×00000001).

This should let you change the “Show Hidden Files and Folders” option now.
Be safe, be careful, use protections, ensure prevention and avoid cure hassles.
