Comment 3 for bug 631758

tbzrcommand.exe, tbzrcommandw.exe and tbzrcachew.exe are present in the official Bzr 2.2.0 installer; I just checked on a fresh system.
tbzrcommand.exe is working properly, but not tbzrcommandw.exe.
I can confirm the proper working of bzrw, so as far as I'm concerned, the issue is closed.
You might want to remove the obsolete files from the distribution and update the documentation.
