I'm fighting windoze Hypertrm right now over this issue trying to read from a freq counter for some ADEV measurements.   Once HYPERTRM runs, no other program can access the serial port.

One trick with Windows is to disable and then renable the serial port, 
in particular, USB ports sometimes get stuck, and this fixes them.

There's also some power management things with USB connected ports that 
can get things confused.  (You don't want USB selective suspend enabled)

there's a command line tools that can do this, or you can use Device 
Manager.

all sorts of useful stuff.
