I suspect that's often enough to easily stay under that threshold. For me it's at most every 3ish months that i boot windows for one particular game that releases updates in 3 month cycles. Sometimes I skip one or two and then it's 6 or 9 month between boots.
And everytime it just reboots me, no prompt, nothing, just in the middle of the game, good-bye.
The worst I have experienced is slow downs in game because it chose to update in the background.
