If you share your computer with other users or manage the computers in your home or office, there are times when you may want to restrict users from changing folder options, such as making Windows system files visible which are invisible by default or showing file extensions. To do this, go to the Windows Start Menu and click on Run . Type “regedit” to launch the windows system registry tool. Next, go to: HKEY_CURRENT_USER / Software / Microsoft / Windows / Curre ntVersion / Policies / Explorer. It may be a good idea to backup your registry at this point . After creating a back-up, double-click on NoFolderOptions and set its value to 1 . After doing so, users will no longer be able to edit Folder Options. To reverse, set the value back to 0 .
