There's definitely something that's getting in your way.  Anti-malware
and anti-virus programs can do this.  And they sometimes requires you to
uninstall the offending program to remove the restriction.  Just disabling
is a good first step but it's not always enough.  But other software
(malware, viruses, drivers, etc) could also be the cause.  One thing you
might try is rebooting into "Safe Mode" to see if the behaviour differs.  It
should and that might help you narrow down the culprit.

The fact that this behaviour happens even if you're not using Cygwin makes
pursuing this further on this list off-topic.  While it would be perfectly 
acceptable for you to report back what you find (for the archives and for
those reading the thread that are curious :-) ), further diagnostic help
and suggestions, if needed, really should be directed to some Windows forum.
