Great story, I never knew about that. Mainly because I never had a DOS-based Windows system that managed to accumulate 50 days of uptime.
Windows Server, yes. Win7, yes. Win95/98, not so much.
While studying for my Winnt 4.0 MCSE cert I constructed a home network. I had one corner of a back bedroom that was susceptible to mildew so I located the PC running NT server there and strung Ethernet to the rest of my mockup. It emanated a soft heat that kept the walls dry.
When I moved to my new home I got curious and ran uptime on the server before shutting down. It had been running nonstop for over 4 years. I decided to do a full backup - which was a good idea because the HDD wouldn’t spin up after the move!
