Build 19577 installed overnight. Going through my usual reconfiguration today, I finally noticed something: new build installs don’t re-enable the Windows 10 lock screen (IMO, a pointless feature on single user immobile desktop PCs), but they do reset shortcuts to display the shortcut arrow overlay. A small inconsistency, but if one can be left untouched, why not the other? Actually, there are a dozen changes I make which need to be remade with each new Insider build.
