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:

I'm hoping someone else has figured out a way around this. Its no problem on linux....
