It doesn't necessarily need to be intercepted. I remember on Windows 7 I managed to create a small program which opened a screen-filling window with the close button disabled and the "always on top" property. I could press Ctrl+Alt+Del as much as I wanted, the task manager always opened behind my program's window and so was pretty useless. Then again Windows 7 still had some quirks here and there, maybe it's different now.
- barrkel 6y agoCtrl-Alt-Del, from the old NT days, was a Secure Attention Sequence, theoretically not interceptable short of a kernel driver, and took you to a separate desktop. NT supported separate desktops, but they're not like virtual monitors you see today; they're more like separate virtual ttys in the Linux console sense, entirely separate desktops with wholly detached window environments running on them. That's where the lock screen lived, and where Ctrl-Alt-Del took you to. Windows 7 probably changed that somewhat. I know the lock screen in Windows 10 is super buggy wrt customisation.
- frosted-flakes 6y agoCtrl+Alt+Del doesn't open Task Manager directly, it opens a separate full-screen menu that looks like the login screen with options for shutting down, logging out, or opening Task Manager. It's been this way at least since Windows 7, but probably earlier.
