Hi Ted and Alan,
I would guess there is a 98.72% chance everything will go fine and it will run all your programs if you were running Windows 10 successfully before. The upgrade to Windows 11 is more like a small update rather than a upgrade to a new major version of Windows version. Yes the interface gets a refresh and most of it is nice, but there was some things like how the taskbar and context menus work that would have been deal breakers for me if I had not come across some friendly hacks which brings back some of the old style menus and functions. If I did not have to support other users, I would have downgraded back to Windows 10 myself. Actually, in fact I actually did after my first 15 mins with it before I realized I would need to figure things out to support my users. My solution so far has been using a combination of
Start 11 by StarDock and an open source project called
Explorer Patcher which has been a godsend.
The underlying core of Windows 11 is primarily the same as Windows 10, but unless you have a compelling reason to upgrade I would still hold off a bit. There is a Windows 11 update coming in Feb but it's still missing the return of some major removed items in my opinion. I would watch some review videos on YouTube to see if you would like the interface changes or not first. Then if you think the simplified interface would work for you, maybe wait a couple of months after the February update is released. If all goes well with that, then upgrade at that time.
You are not missing out on anything important if you do not upgrade to Windows 11. Windows 10 should be supported thru 2025, so you have plenty of time.
