Did you make them aware of this thread?
It's a reasonable question Higgled, but one that at best would be anecdotal (as there is no cross referencing from MS to us on support issues), and we already have sufficient anecdotal evidence above to go along with (as noted by Leathlean) early contributions by MS Moderators that
1) Offered both an explanation and proposed (TWICE) the same solution – “buy new hardware to go with your new OS” (Afzal Taher)
2) Requested supplemental information, implicitly to duplicate and remedy the situation (Kevin Hau)
IMHO, the best MS could offer at this point is that this issue simply isn’t on their priorities list.
I for one have suspended migration of 150+ PC’s from XP to Windows 7 in no small part due to this specific issue. Not necessarily because of the KVM/Display, but the lack of response and clarity by MS. Lord help me if there is another issue affecting 10% of my users for which there is a) No Response b) required new, unplanned expenditures to resolve.
