Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

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. 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.
