Error 1001. The specified service has been marked for deletion

During windows services development there are periods during the final deployment process where I'm installing and uninstalling services pretty rapidly on a server and I occasionally run into this message: "Error 1001. The specified service has been marked for deletion." This error message will cancel the installation and, if you Google around for cures to this problem, the general consensus is to reboot the system.

The systems I work on require extensive permissions from a lot of people/departments to reboot, bringing development to a halt, so I found an easier way to get around the problem. It turns out that the error message is actually complaining that "services.msc" is currently open (in my case, I've left the server manager app open to list current service statuses), so stopping this process (again in my case, simply closing server manager) allows the service to be installed.
