Hey guys, I've got HP Pavillion dv4-2040us laptop that came with Windows 7 Home Premium preinstalled. Since I don't like the bloatware that came with it, I've decided to reinstall Win7 and turn it up a notch and make it Ultimate... The questions is, can I activate my machine with an Win7 Ultimate key that I have from Dell using the OEM SLP method? Is the BIOS that HP have posted already includes the SLIC2.1 Mod? Which certificate do I need to use if I want to activate with the OEM SLP method? Direct Link: Thanks for your help!
