Hmm, maybe that's the problem. This "Microsoft Account" stuff might
influence how the underlying OS handles permissions. I would never
touch this stuff ;)
For testing you could try to create a normal local account, add it to
/etc/passwd and run the above under this account. If it behaves
differently (correct, that is), it's a something weird with these MS
accounts. But then again, I wouldn't know how to "fix" this, other
than to suggest to use a normal account instead.

Nah, at this point we really don't know why this happens on your machine
and it could easily be somebody elses fault.
An strace of `chmod 400 bar' might sched some light on this issue, but I
have a gut feeling the underlying WIndows call will not even return an
error code...
