In the Win32 API, commands can't be invoked with the cwd being a UNC path. This context manager temporarily changes directory to the 'C:' drive on entering, and restores the original working directory on exit. The context manager returns the starting working directory *if* it made a change and None otherwise, so that users can apply the necessary adjustment to their system calls in the event of a change.
