Problem with manual upgrade to Drush 6 on Windows XP

We installed drush on windows xp using the windows installer from drush.ws
We then did a "drush status" in our sites root directory and it ran as expected.
5.8 works great

We then downloaded drush 8.x-6.x-dev from drupal.org/project/dush
Extract the zip to a temp directory.
Renamed the existing directory c/Documents and Settings/All Users/Application Data/Drush to ... Drush_old
Copied the newly extracted drush directory to c/Documents and Settings/All Users/Application Data/Drush.

below is the output from when we ran drush status, drush dl backup_mirgrate, and drush site-alias. The main issue is we get the error message

/c/Documents and Settings/All Users/Application Data/Drush/drush: line 82: [: too many arguments
sh: line 0: cd: /c/Documents: No such file or directory"

Here is our output

$ drush status
/c/Documents and Settings/All Users/Application Data/Drush/drush: line 82: [: too many arguments
sh: line 0: cd: /c/Documents: No such file or directory

Also, when we run the drush status in a windows cmd (dos window) it runs fine. No error messages. But when we run it in a git bash window, you see the above errors. I check the path for both environments and they are the same.

I am including the path just in case someone needs it:
