A while back i wrote about this patch which killed OCS… (which the OCS team have now fixed)
I got an email today from one of my guys saying that it also killed USMT… sure enough, i just ran into the same thing….
The SMSTS.log reports

un-install this “patch” from the client – and the issue goes away…. moral of the story… avoid kb974571…. everywhere.
