This tweak allows you to remove the Make Available Offline option from
the context menu (on right click).This applies to all (!) files and folders
from network resources.To do so move along :


- HKEY_CURRENT_USER\Software\Policies
\Microsoft\Windows\NetCache \


(It is possible that you need to create the NetCache subkey when it does
not exist.Navigate to the Windows key , right click , new , key . Name the
key : NetCache)

Create or modify now in the right pane the entry :

NoMakeAvailableOffline

(right click in the right pane , new , DWORD [DWord Value] and name
it as above)

Doubleclick the NoMakeAvailableOffline entry and set it's value to 1.

To enable it again set it's value to 0 or remove the entry.
