Ctrl-Alt-Delete in Windows on Bootcamp

The Macbook keyboard layout maps "Delete" to backspace which effectively makes it impossible to hit Ctrl-Alt-Delete unless you have an external USB keyboard.

The Windows Server 2003 Resource Kit comes with a handy tool called remapkey.exe but if you don't want to download it, just save this code to a .reg file and double click. It maps the right "Windows" key (The right Apple key) to be a "Delete" button. Windows Registry Editor Version 5.00

Note: This tip targets Intel-based Macs running Boot Camp-era Windows (XP/2003/7 timeframe). Apple Silicon Macs do not support Boot Camp; for modern setups, use a Windows VM and configure the keyboard mapping within the hypervisor instead.
