can't see Hidden files/folders HIDE FOLDER

I can't see Hidden files/folders in my computer. Even I enable the option "Show hidden files/folders" in "Tools -> Folder Options", its automatically disabled again.

Sol: Open regedit and goto:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Current Version\explorer\Advanced\Folder\Hidden

Under this key, you'll see 2 more keys "NOHIDDEN" and "SHOWALL". Make sure that the values of "CheckedValue" and "DefaultValue" in right-side pane are "2" and "2" for "NOHIDDEN" and "1" and "2" for "SHOWALL" respectively. If its not so, then change them and you'll be able to enable/disable these options in "Folder Options".

You can also alter Hide/unhide settings using registry as following:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Explorer\Advanced

In right-side pane, change value of "Hidden" to:

1 - To show hidden files
2 - To not show hidden files
