check the start menu of your os because its not on a disc i think lol or when i did it i put the acer ultimate oem:slp key in and it upgraded to ultimate without a disc in about 10 minutes
HP has every driver you need! Search HP Support Center by keywords (for example "authentec" for fingerprint reader), don't look at your laptop model. My laptop is from 2006, Win 7 is not officially supported. But I found all drivers without a problem, and I'm talking about real Win 7 x64 drivers, not about Vista stuff (besides graphics, here I have to use Vista driver from ATI).
:O!!!! Thanks a lot for the fast replies!!! Im gonna try what Servi did 1st, if not, im gonna upgrade. =D
I also want to upgrade to Windows 7 Ultimate to my HP Elitebook 8450P notebook. Have you successfully upgrade your HP notebook to Windows 7 Ultimate ?
There is no problem using AnyTime upgrade with a OEM-SLP key. But you need a computer with SLIC 2.1 in BIOS and a certificate. All new computers with Win7 have this, so if you have a new computer, use AnyTime upgrade and the OEM-SLP key and you can upgrade "free" to any version you want. This do not work on computers thats not comes from the Royal OEM producers like Dell, HP, Acer etc. (if you not have mod your BIOS then) You don't need any CD/DVD so it's no problem trying. Start the AnyTime upgrade program from you start menu, type inn the wanted OEM-SLP key, and start. A smart thing to do is to use the key to the brand you have, but it's not necessary.
