I've had Windows hang due (apparently) to OOM before now, most recently last week: already low on free memory due to other things, a runaway chrome tab chef through a huge pile of memory overnight. Come morning everything was at a crawl (task manager responded quickly but everything else took an age to register any event like a click or keypress. Bringing up chrome's task manager, sorting by RAM use, and navigating to the top of the list, to find the problem, took several minutes. Switching to that tab hung everything, even task manager. This was running in a VM so I could see from the host that the OS has hung: practically no CPU or IO use, what little there was was likely just "background noise" from hyper-v, also not even the simplest service accepted TCP connections nor would it respond to ping. Left it like that for tens of minutes to see no change, so resorted to a hard stop & start. It happens, albeit quite rarely.
