CTRL+B (Quit Local Debugger)

The CTRL+B key causes the debugger to terminate abruptly. This does not end a remote debugging session.

CTRL+B  ENTER

Remarks

In CDB, the q (Quit) command should be used to exit. CTRL+B should only be used if the debugger is not responding.

In KD, the q command will end the debugging session and leave the target computer locked. If you need to preserve the debugging session (so a new debugger can connect to it), or if you need to leave the target computer running, you should use CTRL+B.

In WinDbg, the equivalent command is File | Exit or ALT+F4.
