Windows 7 Professional SP1 - x64 [Non-UEFI Boot]

Therefore you can uninstall safely any of the "Intel Rapid Storage Technology", before the new install from "Program & Features"...The official version of Intel is now v10.1.0.1008 but i'll suggest you to take the HP Stock drivers then update if everything is stable for you.

Happy new year all!
