Many times Windows users face a common problem. The “Folder Options” in “Tools” menu is not visible. Even It can’t be accessed from Control Panel. Also “Registry Editor” is disabled.
Follow the simple steps mentioned in this tutorial and your problem will be solved:

1. If Folder Options is disabled but Registry Editor is still working in your system, then you can enable Folder Options by editing Windows Registry.
Type regedit in RUN dialog box and press Enter.
it’ll open Registry Editor, now go to following keys:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\ExplorerHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\Explorer
In right-side pane, check whether a DWORD value named NoFolderOptions exists or not? If it exists, delete it.

2. If you are not familiar with editing the registry, then you can simply download following file, extract it and then run the .REG file:
Folder_option.zip
