I am running Virtual PC 2007 (6.0) on a Windows XP host. My virtual boxes are all Windows Server 2003. Every so often, key repeat stops working.

Normally in Windows if you hold down any key (Space, X, etc.) for half a second, the key starts repeating. In all of my virtual boxes, key repeat doesn’t work.

Restarting a single virtual instance doesn’t help. The only thing that seems to work is rebooting the host, which is a real pain as I am running Domain Controllers, etc. on all the virtual boxes.

Is there a fix out there for this? Google was not my friend on this issue.

UPDATE: Still having this problem about once a month, I did discover that I could save state on each instance and reboot the host, the functionality returns and it is faster than shutting down each virtual instance and rebooting the host.

Have you set the keyboard repeat in each of the guest OSes? – Synetech Feb 25 '12 at 5:12
Keyboard repeat hasn't changed in any of the boxes. It just stops working. Even virtual boxes I don't use (like the DC) it stops working. I rebooted over the weekend and it works again. – CigarDoug Feb 27 '12 at 11:16

So, I finally figured out the problem: The Shift key on my keyboard was locking at random times, which caused the issue. Replacing the keyboard corrected the problem.
