Recently, this problem became a regular one as a big number of computer viruses disable this option “Show Hidden Files” on your Windows Vista operating system. The option disappears from the “Folder Options” dialog and it seems like there’s nothing left to do. Not being able to see the hidden files and folders on your computer can be an issue that endangers the security of your data.
Now, the solution:
The best you can do is to perform a virus and spy ware scan on your computer but there’s a good chance that the option would still be unavailable. However, you can restore the option by doing a Manual Registry Tweak.
Open the “RUN” box by pressing Windows key + R. Type “regedit” and then navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Advanced\Folder\Hidden.
Locate the key named “Type” and change it’s value to “group”. This will fix your problem and you’ll be able to use the “Show Hidden Files and Folders” option on your Windows Vista.
