Show Hidden Files and Folders not working?

Sometimes due to a virus on you windows machine, the show hidden files and folder radio option refuses to work no matter how many times you select it.

There is a couple of tricks you can use to resolve this issue, both require you to make changes on your registry so please use extreme caution.

Method 1:

Go to registry editor by running regedit in the run box.
Go to this key:
HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Explorer\Advanced

In the right hand area, double click hidden and change the value to 1.

Now you’re all set to go. Check it in your tools menu if the changes have taken effect.

Method 2: (By Random Hajile)

1. Click “Start” -> “Run…” (or press Windows key + R)
2. Type “regedit” and click “Ok”.
3. Find the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\
Advanced\Folder\Hidden\SHOWALL
4. Look at the “CheckedValue” key… This should be a DWORD key. If it isn’t, delete the key.
5. Create a new key called “CheckedValue” as a DWORD (hexadecimal) with a value of 1.
6. The “Show hidden files & folders” check box should now work normally. 

Enjoy!
