Disable "Show All files" option in Folder options in Windows XP/2000

If u want to hide hidden files and folders from appearing from some one permanently is to disable folder option from showing show hidden files. This can be done with a registry trick.
Start>Run
Type Regedit
This opens the registry editor
Navigate to the following key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\HiddenSHOWALL
The key Type contains the string value named radio. This is resposible for showing the radio button. Rename it to 'ABCD' and close regedit. The show hidden files option will not be there in folder options. You can still navigate to folder through address bar if u know address. You may have to reboot your PC to changes to take effect.
