According to Guinness, the top is Voyager 2:
> The computer system that has been in continual operation for the longest period is the Computer Command System (CCS) onboard NASA's Voyager 2 spacecraft. This pair of interlinked computers have been in operation since the spacecraft's launch on 20 August 1977. As of 29 October 2020, the CCS has been running for 43 years 70 days.

Not a lot of bugs in space, so it is hard for them to get in....

43 years without a single reset or revision to safe mode (a common feature on spacecraft)? The linked article says that they've updated the software many times, by live patching it, instead of rebooting?

Since there are 2 computers I'm guessing that they are letting one computer update and reset the other one, then repeat for the reverse. The system as a whole would stay up, the individual computers would not.

That's very interesting. Your comment got me searching and I found a link here on HN: "Stratus: Servers that won’t quit – The 24 year running computer" with quite a discussion (123 comments) on the topic:
