Acabo de instalar Python en Windows 10, y estoy tratando de actualizar pip.

Mi nombre de usuario de Windows tiene caracteres hebreos ...

Cuando trato de correr:

python -m pip install --upgrade pip

Me sale este error:

You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Estoy geussing esto tiene que ver con mi nombre de usuario de Windows hebreo, ¿es correcto?

¿Puedo actualizar pip sin abrir un nuevo usuario de Windows?
