How to view more than 64 snapshots (shadow copies) on Windows 7 / Windows 2008

Windows can store a max of 512 Volume Shadown Copy Snapshots. But you may have noticed when you go to view the list of snapshots in Windows 7 or Server 2008, only 64 are displayed.

*****Use the following at your own risk and watch to make sure you do not have network performance issues after implementing this*****

On the server perform the following regedit to enable viewing more than 64 snapshots:

HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters
Create a value with the name Smb2 and type DWORD.
Set the value to 0
Reboot the server

Try viewing snapshots and you should now be able to see more than 64 provided you have configured your server to store more.

Incidentally, if you want your server to provide more snapshot perform the following regedit:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VSS\Settings
Create a value with the name MaxShadowCopies and type DWORD. Set the value to the number of snapshots you want to keep. The max is 512
Reboot the server
