And here I am slowly migrating my main programs, and work environment to Debian Mate to leave the Microsoft Ecosystem. (Plasma looks nice and polished so I'm struggling a bit though). I'm still on Windows 7 Pro with updates disabled so luckily I avoided the recommended 'security' updates (*cough* "Edge" *cough*). The only thing holding me to Windows is gaming. Debian Mate "Live USB" w/ persistence is more than adequate for my daily needs such as browsing, programming, and relaxing.
Windows 7, Palemoon browser (portable version, noscript, ublock) along with a pihole with aggressive filters and a firewall with aggressive settings and lots of garbage in my hosts file. It stops a lot of garbage but it also breaks a lot of sites.
In one particular circle of users I'm around, Windows 10 was a huuuuuuuge unmitigated disaster with people running machines 24x7 who operate local weather stations. The incessant rebooting, system wide configuration changes, and a host of issues made Win10 useless for that environment. Its gotten better though. Luckily on my WX server still runs 7 and I haven't had any issues with it.

I miss Windows 2000 Pro. An operating system to get work done with no social media installed.
