I finally had time to replace the old PC I run Roon on with latest Asus Nook 15 Pro mini-pc, cost <1K. This is most recent Windows 11 model configured with a lot more horsepower than my old similar form factor Windows 10 model, so was ready for an upgrade, especially in that Roon had been fussing about running on it quite a bit of late.
So far so good. Very compact, excellent performance, very quiet running. Roon is zipping along quite optimally now.
I’ll post if anything changes but looks like a winner for running Roon. All problems gone, at least so far.
Moving my programs from old Windows 10 to new Windows 11 was a breeze, including Roon. All my Roon files are on a remote USB drive which I just connected to new PC, then shut down old PC, installed Roon on new, logged in, and restored my library from backup.
Nice!
