Yes, all Exchange services are running again. They were stopped during installation, as usual. Then, they started up automatically, but Windows update is still showing "Installing update 1 of 1...." and the bar is about 95% full. I'm wondering, if it's just a display bug. However, in the task manager I can still see some "Windows installer" processes running, but all at 0% CPU. Haven't had this situation before. Usually, shortly after the Exchange services come up again, Windows update finishes the installation.

Edit:
I just ran HealthChecker and it says all known security issues passed. Everything looks fine. Reboot pending. So I guess I let the server restart over night?
