So I bit the bullet, And upgraded to Windows 11 (Insider Preview) Everything went ok on the install wasnt sure what way it would go because I’m dual booting Win 10… But installed ok and MBR BCD intact… Performance wasn’t as good as I’d had before… some slight stutters on a quick flight from London to Dublin and just reaching Coast of Dublin as always VCRUNTIME140.dll, and some new ones GameBar.exe, - Windows.UI.Xaml.dll, - ucrtbase.dll,… So there you go upgrade to Win 11 for me didnt fix anything unfortunately
I am guessing you can reverse the Windows 11 install but not sure. Beta software is for people that are ok with problems and crashes. I beta test Active Sky mainly to report issues, but at least with that I don’t have to run Active Sky with P3D. That said I don’t recommend installing Windows 11 until its ready.
