Hidden files and folders not being shown?

Have you ever experienced this peculiar problem? You set the folder options to show Hidden files and folders, but if you close and reopen the options, it reverts to 'Don't Show Hidden Files'? If there are no virus attacks, this problem can be solved in the following way.

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:

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.

The second method worked for me.
