You know that moment when you have to desperately have to print something and there is a job in the printer queue which will not die without a restart of your computer and/or the printer and you curse and sear about how much you hate windows and printers??????
Copy the following into a text file and save as KillPrintQueue.cmd
net stop spooler
del %systemroot%\system32\spool\printers\*.shd
del %systemroot%\system32\spool\printers\*.spl
net start spooler
save it in your dropbox so you don’t lose it from machine to machine.
Run it
JOY TO THE WORLD !!!!

I found this trick a couple of weeks ago. Works great normally, but for some reason my HP printer *still* locks to the print files even after shutting down the service, so its, shutdown, reboot, then delete. Isn’t windows printing lovely!
