Bookworm was, for me, the first one that installed fine for me. I love the philosophy of Debian but I might also like Arch - the bleeding edge is very attractive and I think I like AUR, however I need to understand how that works some more, before daring to do the jump.

You can also get Teams on Linux

I’ll just say that I don’t think you’ll ever get stability with 8gb for win 11

First, I’ve never tried using Linux as a VM host, so there might be something in play I don’t know about. However, having run Windows 11 as a guest under Windows 11 and macOS, I can push Windows 11 down to 1 GB of RAM With no problems. It’s a little sluggish when opening apps but never unstable. Normally I run it with 4 GB.

I think you underestimate how many computers that are in use today that can’t be updated to Windows 11.

I, and many others, have run Windows 10 on unsupported hardware. Difference is that Windows 10 didn’t care and Windows 11 actively try to stop you from doing so. So, what is this if not Microsoft now forcing people to buy new hardware, if they have unsupported hardware?

Edit: What where the CPUs on the 2015 computers you upgraded?
