Blue Screen Problem

[Cris1]

I recently upgraded my Windows 7 Home Premium SP1 to Windows 7 Ultimate, It restarted my computer and this
blue screen showed up.I turned off my computer using the button in the CPU then turned it back on after that
It worked properly but I posted this because I dont know if it is going to happen again when I turn my Computer back on . Thanks!

Which special additional expensive features did you need in ultimate that weren't in Home Premium? It's the exact same OS otherwise. Do you own an Ultimate license? If not I would reinstall the OS for the license you own.
