24.3; emacs hangs under windows 7

Went to try this out on a machine at work.

In Windows 7, Emacs hangs for 4 to 10 seconds every few minutes. Tried
emacs and runemacs from the Windows GUI via mouse clicks.

Then from the cmd tried them again.
Then tried emacs -Q and runemacs -Q from cmd.
Tried downloading Cygwin and then emacs from inside Cygwin.
Haven't had any problems from in Cygwin in the same version, 24.3.1.

This is a work machine and have only had it for a few days, so I am not
entitled to full freedom/control over it and it is possible something is
wrong with the machine (well, don't get me started =D ). Happy to try other
options.

Definitely don't have this issue anywhere else (such as Trisquel).
Definitely seems to be Windows related.
