I noticed that the Edge (not that I use it) and Virus Definition updates are still happening on my Windows 10 system, as well as updated for third-party software, so since the major Windows updates happen/ed on "Patch Tuesday" there's still a month until the next one on Nov 11 and Windows gets completely left behind, from a practical point anyway.
I've had my (more capable) Linux Mint 22.2 (Cinnamon) system up for a *while*, but am (still) being lazy about moving all my files over to it. I've sync'ed my Firefox and Thunderbird configs and files, and converted all my MS Office and (older) Lotus 123/WordPro files to LibreOffice, and renamed a bunch of files to remove embedded white-space and make them more Linux / command-line friendly. Just need to bite the bullet and start copying things over ...
Am still not completely happy about the Linux alternatives to AxCrypt (ignoring the 34MB Linux command-line version); I'm considering "ccrypt" and/or "7z" for various things as they seem relatively simple and portable (even to Windows, ccyprt via Cygwin). Looked into and enabled native VIM encryption, but don't really want to be tied to it. For ccrypt there's a Emacs module that supports it and I've found/created Nemo actions/scripts for en/decrypting from the GUI.
