any idea how to update python PIP on a windows box?

Question

pip install --upgrade pip doesn't work because the windows FS is brain damaged and won't let you delete an open file.

I've tried setting my environment to the virtualenv that I want to update and then running from a different pip, but that fails with:

(jm) E:pythonjm>c:Python26Scriptspip install --upgrade pip
