After an upgrade to Windows 10 20H2, the MS Edge browser started hogging the Alt-Tab switcher and injecting its tabs into it.
It seems right now it injects up to 5 tabs.
This is very annoying, as switching away from MS Edge takes anywhere between 1 to 5 presses of Alt-Tab (depending on how many tabs are open).
Hence the question: how to make it stop doing that?
