Remove KB974674 after migration

So during migrations some people are installing the ntbackup code on their SBS 2011 boxes.  This allows you to restore data from your SBS 2003.  <Unconfirmed at this time> It appears that on some hardware configurations or setups if you leave this ntbackup code in the server and then attempt to do a bare metal install, you'll end up with a blinking cursor on a black screen.

The moral of this story is, when you complete the process of migration, uninstall KB974674.
