I looked into all of the above, and nothing is working (I also asked MS directly through their community and got useful though ineffective help). This is more of an annoyance than anything else. The PC in question is a Probook 430 G3, which is ineligible for Windows 11 (so, of course, I installed it 😉). It works like a top but has this annoying Conexant driver (which is old and - apparently - related to Windows 10) pop up all the time. Somehow, I was able to get rid of the nagging in the 2021 versions of Windows 11, but it has resurfaced in Windows 11 22H2 (simply because I had to do a clean install). Any other ideas? Not a "showstopper" but I'd really like to get rid of it.
