Startup options can be tricky, Your slow start could be any one of several driver
programs. I would recommend that you either use msconfig or a free program called startupinspector to see what is starting
up when you boot. Some computers from OEM's* put all kinds of junkware in them and each one slows things down a bit continually checking for updates and such.
*(original equipment manufacturers, like Dell, Hp and such)
Additionally, Adobe and others like to install version/update checks in your startup routines, which will
slow down any computer.
