On my old computer, when caps-lock is activated and I press the shift key, it disables the caps look.
On my new computer under windows 11, when caps-lock is activated and I keep the shift key pressed, it inserts lowercase letters but when I release it, caps-lock remains activated.
How to get the old behavior (press shift turn off caps-lock) on windows 11
Remark: I use french layout where this behavior is suposed to be default https://en.wikipedia.org/wiki/Caps_Lock#Behavior
It's done just like under, or at least close to, win 10.
This should open a window called "Text Services and Input Languages" it should contain an "Advanced Key Settings" section where you can switch between the two modes of how to turn off Caps Lock. I find that a lot more comfortable as well and is usually one of the first things I change when setting up my profile after a fresh windows installation.

That is most likely a function of BIOS in the old computer and is not standard behavior on any computer I have (or have had).
So you will need to use the Caps Lock key to both toggle Caps ON and then OFF. - This is quite normal.
