Unable to delete driver, print spooler windows vista & 7

According to this article (http://www.mysysadmintips.com/clients/170-cant-remove-printer-drivers-in-windows-7-the-specified-printer-driver-is-currently-in-use) pressing delete driver a second after the print spooler has started is the way to delete the driver. Strange but true, it worked for me! Probably because the driver is loaded a couple seconds after the print spooler has started.
