WinDbg Easter Eggs

Today I stumbled across (via the OSR Twitter page) a funny Easter egg in the !ndiskd kernel debugger extension for WinDbg.

!ndiskd.help does as you’d expect and prints info about the commands within that extension:

ndiskd.help

If you ask for help with a sense of urgency:

!ndiskd.help!

urgent

It exclaims “Don’t Panic!”


I sent this to all 3 of my other friends who think WinDBG jokes are funny, including Alex Ionescu, who deserves credit for bringing my attention to another cutesy undocumented debugger extension.

It is exactly the same thing as !chksym, but with a more amusing name.

Let me know if you are aware of any other fun undocumented WinDbg Easter eggs like these - I’d love to hear.
