One of the things I never really noticed is the change in the behavior of the Shift Lock keys over the years. Somewhere it seems to have changed. I use it very rarely, but some users do. The complaint we received was that in the past they could just tap shift and it would unlock the shift lock, whilst now they really had to touch the shift lock again. Well it seems it’s actually pretty easy modify this behavior:

Open the Region and Language section in the control panel, choose they Keyboards and Languages tab and then click Change keyboards

Now pick the Advanced Key Settings tab:
