Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

This update adds new functionality that lets you perform either of the following actions:
  • You can disable the Previous Versions tab on individual client computers.

    Note To view the Previous Versions tab, right-click the file that you want to restore on the network, and then click Properties. If the Previous Versions tab does not appear in the Properties dialog box, the Shadow Copies of Shared Folders feature may not be enabled on the shared resource.
  • You can disable only the Restore button on the Previous Versions tab on individual client computers.
This functionality prevents a client from overwriting the current version of a file with an earlier version of the file. The client can only copy the earlier version of a file to an alternative location.

To enable this functionality, you must add a DWORD registry entry to either of the following registry subkeys on the client computer. You must do this after you install the update on the client computer.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

You can add the DWORD registry entry as part of a user's logon script.

We recommend that you add the DWORD entry to the HKEY_LOCAL_MACHINE subkey. We recommend this for the following reasons:
  • The HKEY_LOCAL_MACHINE subkey is not overwritten by policy updates.
  • The HKEY_CURRENT_USER subkey can be written to by logon scripts that are using nonadministrator permissions.

To disable the Previous Versions tab

To disable the Previous Versions tab on individual client computers, follow these steps:
  1. Click Start, click Run, type regedit in the Open box, and then click OK.
  2. Locate and then click either of the following registry subkeys:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

  3. On the Edit menu, point to New, and then click DWORD Value.
  4. Type NoPreviousVersionsPage, and then press ENTER.
  5. Right-click NoPreviousVersionsPage, and then click Modify.
  6. In the Value data box, type 1, and then click OK.
  7. Quit Registry Editor.
Alternatively, you can use the Reg.exe utility to disable the Previous Versions tab. To do this, type either of the following commands at the command prompt, and then press ENTER:

REG ADD HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer /v NoPreviousVersionsPage /t REG_DWORD /d 1

REG ADD HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer /v NoPreviousVersionsPage /t REG_DWORD /d 1
