Some of Microsoft's tools support formatting output as XML or JSON, which can generally be parsed more reliably. For example:
import subprocess
import xml.etree.ElementTree as ET
p = subprocess.run('wmic.exe os get Caption,Version /format:rawxml',
capture_output=True, encoding='oem')
root = ET.fromstring(p.stdout)
caption = root.find('.//PROPERTY[@NAME="Caption"]/VALUE').text
version = root.find('.//PROPERTY[@NAME="Version"]/VALUE').text

Please propose a PR if you prefer to parse XML than plain text. I don't want to invest too much time in this code, since I'm not using Windows :-)

Well, maybe a more "correct" implementation is required if the function enters the stdlib platform module, but this PR is only about test.pythoninfo which is only used ... for tests ;-)
