The anonymizing relay monitor (arm) may not be usable for TBB windows users (or is it?). What alternatives exist for TBB window users?
Your best bet is Vidalia. This must be installed manually. However one of the Tor developers has some pre-built binaries. Select the one which fits you best and download it. You can extract (or execute in Windows) the package to any directory. Within the extracted files is a script called
start-vidalia. When you execute it Vidalia comes up.
When Vidalia doesn't connect automatically to a running Tor instance, you'll have to configure it. Click on Settings and find a line with the word tor. On the right side is a button Browse. Click on it and enter the correct path to your Tor executable. This is usually the subdirectory
Tor of your TBB installation. Now save your settings.
Try to play around or use Vidalia as you're used to.
You might also want to have a look a trac entry #8641. The transition from Vidalia to another solution is discussed there. Probably other solutions can be found in the future there.
