Description of the Windows NT Backup Restore Utility for Windows 7 and for Windows Server 2008 R2:
The Windows NT Backup Restore Utility for Windows 7 and for Windows Server 2008 R2 is not intended to remain on computers that are running Windows 7 and Windows Server 2008 R2 indefinitely and should be removed once you have restored backups that were made on Windows XP and on Windows Server 2003.
Let’s make it really clear what happens if you leave this installed.
You install that to restore some data from a 2003 era backup. You install it on a SBS2011 server. You then go on your merry way and make backups. You go to do a bare metal restore and upon the first boot you end up with a black screen. Not a good place to be in.
Bottom line, if, for any reason you use this KB to restore data from a 2003 era backup to a 2011 machines, make sure you uninstall it and kick a manual backup. Any backup made with it uninstalled will work just fine. Any backup made with it installed will work to restore, just bare metal restore will be messed up.
