That could cause issues if the files are mismatched.

Then also, you could potentially have TWO months worth of patching pending... (and that's not including feature updates and out of band stuff)

Also, at up to potentially 65ish days of not rebooting, you haven't noticed a performance decrease due to memory leaks?

I have seen older Windows systems that have not been rebooted for up to three years at a time because the app support team didn't want the monthly alerts (and somehow disabled the patching agent)... Let's just say the audit departments had a field day with those teams and some very nasty penalties were issued.

Anyway, my point is, disabling the auto reboot is a bad idea. I'd configure it to reboot outside of active hours at the very least. But definitely manually reboot at least once a week.
