Bug upgrading to 1.7.4 with MS Lync running.

Windows 7, 64 bits, fully updated.
64 bits TortoiseSVN, updating from 1.7.2 to 1.7.4
Running update as member of administrator group, full privileges.
Running update across a remote desktop.
MS Lync version 4.0.7577.314

SVN strongly urged me to update to 1.7.4, and I caved in to the pressure... :)

After installing new files, the installation job presents a list of applications that need to be restarted (as an alternative to do a full system restart). The last entry on the list is Lync, after the Windows Explorer (i.e. desktop).

Lync is hard to stop - it restarts immediately, it won't die. The installation job are waiting for it to die; it won't. So the installation hangs, Lync being the only program running.

The big problem is that everything else, including the Windows Explorer, is already down, so I have no access to any start button / restart option, and cannot restart my machine without pysical access to the Restart button (or power off/on). Ctrl-Alt-Del bring up the Task manager on my local machine, not the remote one. The old trick of starting a remote task manager from the run command (edit field in the Start Menu) is not available when Windows Explorer is dead.

Fortunately, I managed to get hold of a colleague (through Lync(!)) who had not yet left the office for the weekend. Three hours later, and my machine would have been unavailable for the entire weekend. That is unacceptable.

I never tried to update from at remote desktop before, the problem may or may not be related to that.
The problem may be unrelated to 1.7.4; at earlier updates I may have requested a full restart (don't remember).
