Update: I'm still evaluating options, using an older (Windows 7 era) Toshiba laptop I bought expressly for messing around. The nice thing about this one (which I didn't fully appreciate when I bought it) is just how easy and quick it is to swap the internal drive. I now have three configurations, on three SSD drives. First up was the install and activate Wows 10 on the original HDD, then I cloned that to an SSD drive. Then I swapped in a used, reformatted SSD and installed LMDE6 (Linux Mint Debian Edition). I have been playing with Linux. I can learn to live with it, but there are many things I do in Windows that don't seem to have easy analogs in Linux. Plus, I have AutoCAD, and although there are CADD programs for Linux, I haven't found any 2D CADD programs that are even close to being work-alikes for AutoCAD.
So the next step was to try Windows 11. I downloaded an .iso for Windows 11 23H2 and used Rufus to create a bootable USB for installation. I put a blank SSD in the Toshiba and installed Windows 11. I had to manually enter the activation key, but it seems to have worked. That was just last night, so I haven't had time yet to do much of anything with Windows 11. Initial reaction is that I don't like it, but I can learn to live with it (if I can get Open Shell to work with it).
But the end of support for 23H2 is November of 2025, which is only a month later than Windows 10 end of support. When I initially tried to make an installation USB I got an error when I used the 24H2 .iso. Once I had 23H2 up and running, late last night I tried again and this time I think I have a USB for 24H2. Later today I'll see if I can use that USB to update 23H2 to 24H2. If that works, next up I'll try updating Windows 10 22H2 directly to Windows 11 24H2.
