Still, it's remarkable that two separate Seattle-based companies have produced a similarly short time bomb on very expensive and highly visible product development projects.
The joke was that nobody had ever had a Win95 system stay up for 49 days. Mwah-hah-hah.
Seriously, Windows 10 does tend to get dodgy if you don't reboot for a few weeks. I'm not the only one who's noticed. Granted, it's less likely to outright crash, but it acts increasingly drunk.
I made an excercize of rebooting my work computer every Monday, but it really wasn't enough. Now I restart it every time I can.
