Well on my Win8.1 machine I created a local user with the name you give 
and did a fresh install of the very latest Python 3.5rc. I installed 
from the 32-bit web installer and the only variation from the defaults 
was to add Python to the PATH (the last checkbox on the first page of 
the wizard).

It all installed without issue and I was able to do "pip --version" from 
a command prompt to see that it had installed pip 7.1.something.

Now this is on my standard dev machine, ie not a virgin VM, and it's 8.1

The standard codepage for console processes appears to be 850.
