Difficult printers in Windows 7

Ok, so here's another reminder for myself.
From time to time I come across systems that have printers "ghosted" in Devices and Printers. You right-click on them, select "remove" and they're gone .... only they're not! Next reboot, there they are again! Varmits!

It seems that Windows wont remove them if there are documents spooled and un-printed (doesn't matter how old) or sometimes if there are ports that have been created and associated with a printer that are still present.

These instructions help you to remove these pesky items!

1. Right-click on the desktop, and create a new shortcut with a target of 'cmd.exe'
2. Right-click on the shortcut and select "Run as Administrator"
3. Run the printui tool with: printui /s /t2
4. Try deleting the printers. If that doesn't work...
5. Click Start > Run > Services.msc
6. Locate the Print Spooler service and stop it (Right-click > Properties > stop service)
7. Open My Computer and browse to C:\Windows\System32\spool\Printers
8. (you will need to say "Continue" or "OK" to get access to this folder)
9. DELETE the contents of that folder
10. Restart the Print Spooler service
11. Go back into the printui utility (might need to restart it using same method as above) and try removing the printers again. This time it should work. If necessary, check the "Ports" tab and remove any TCP/IP ports that are associated with the old printer
12. Finally, check any other computers on the network to see if any have mapped to the printer. Remove any mappings
