HI mstace:
Thank you for your post. I will do my best to aid you in this endeavor!
I regret that after upgrading to Windows 8, you are missing some functionality from the keyboard. I am sending you a link to "Downloading and Updating Software and Drivers for HP Computers" click here. Have you done all your Windows update? You can run the Windows troubleshooter to aid in this process.
Press the Windows key +C to open charms. Type in troubleshooter. If this has not helped please let me know and I will research further.
