As far as I know, the SAS is not actually blocked. At least it's not in Windows 11. However you can't do anything else until you have accepted or canceled the UAC prompt. So Ctrl-Alt-Del would basically just cancel UAC.
But UAC runs in something called a Secure Desktop, where other applications don't have a way to interact with the prompt dialog (e.g. malware could not "click" the button for you).

I know many people don't like UAC and even disable it, but it's actually not a bad system IMHO.

- IggleSniggle 3y agoI got in the habit of disabling it because it caused the entire system to lock up for several seconds. This was probably the correct behavior in those situations but still super annoying as a user. Maybe not a problem on higher end machines.
- sentientslug 3y agoThis is why they give you the option to just disable the background dimming part of UAC. I’ve had to do this before on slow systems and it fixes it.
