Yep. All of the Windows machines that I actually rely on for work—the ones that I need to be able to start up and immediately use, and need to be able to trust them to keep running without interruption or regression—are completely firewalled off from the public internet, so that they are secure both from malware, and unwanted updates. The rest of my work is done on other, more obedient operating systems.

Windows 95 was capable of 49.7 days of uptime. That's pretty difficult on client versions of Windows 10 unless you take extraordinary measures.
