Answer: It depends.
You need to specify the situation.
Dr. Frank Poole found himself in a depressurize spacesuit, in a frigid orbit around Jupiter back in 2001. He likely froze solid before gut microbes had a chance to recycle him.
In 2013, Sandra Bullock found herself in Low Earth Orbit in a sealed suit, anticipating a warmer, but slower, death by asphyxia. Slowly rotating like a supermarket rotisserie chicken, her microbes would have plenty of time to keep her suit pressurized with tissue break-down gasses.
The end state of these two corpsicles would be quite different.
Even completely sterile tissue breaks down after death. Without oxygen-driven metabolism, compartmentalization inside the cells breaks down. Digestive enzymes are released and the cell auto-digests. This process is markedly slowed at low temperature, and essentially stops once frozen.
Similarly with micro organisms: their chemical machinery stops once frozen.
So the essential question is the rate of cooling. Sandra, who will be exposed to direct sunlight half her orbit and to the IR radiation of night-side Earth the rest of the time, will equilibrate to a temperature which may well be above freezing. Frank will largely be exposed to the background microwave temperature and get little warmth from the distant Sun.
