There are different kinds of commands in WinDbg.

Regular commands, e.g. kb apply to the debugging session. E.g. show stack dump etc.

Meta commands are prefixed with a dot, e.g. .load. Meta commands apply to the debugger itself. E.g. load extensions, show help and so forth.

Extension commands are prefixed with an exclamation mark, e.g. !analyze and !dumpheap are defined in debugger extensions (DLLs that provide additional functionality).
