By default it is possible for users to restore files. By following the next steps you can turn this off so that only Open and Copy can be used.
- Fire up the registry (regedit).
- Browse to: HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer to turn it on or off for the current user or HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer to turn it off for the local machine. I suggest turning this off on a user basis, so that your IT Administrators can still manage this if needed.
- Create a new REG_DWORD with the name NoPreviousVersionsRestore. The value for this entry is 1.
Hope this helps.
