Is it Informations we're looking for, or commercials and MS propaganda ?

I work as a pilot for a regional airline. And I can tell you that "rebooting" (we rather call it resetting) a computer during flight happens, causes no havoc whatsoever, and is well over 2 minutes.
The operation is pretty straightforfard: whenever the "flight warning computer", which is watching all the rest, detects a failure in a computer :
-Either it is _very_ important, and then you have sufficient redundancy to just leave it so (and you don't want to re-use a computer that failed once on something critical...in case the next failure goes undetected !)
-Or you are on the ground with time on your hands, or in flight and it is some secondary stuff: you just pull the circuit breaker for that computer, count 2 minutes, then put it back on. The computer is then usually usable within a minute.
For mission-critical system, such as flight control computers, which control the autopilot, everything is tripled. If two agree and one disagrees, the odd one is declared faulty. On such failures, the crew is often not advised while in flight, as there is nothing to be done. The failure is declared by the flight warning computer after landing, for the benefit of maintenance. Obviously, you can't take off again in that situation.
And if the failure happens before takeoff, the rules are different: in case of a failure, and if the reset is ineffective, you check the remaining equipement against the minilum equipement list, which tells you if the remaining redundancy is sufficient or not. It can allow you to take off, sometimes with restrictions, or forbid the flight.
As a rule, redundacy is such that the fault of a single computer or system (even an engine) is not a problem. Nice to know, isn't it ?;-)
