The only difference in UPGRADE to full install is
1.) insert the UPGRADE disk - when as for a KEY - do not insert a key - the install will continue and become a 30 day TRIAL Edition.
2.) while you are booted to your trial edition - move to the DVD - open and click setup again ... when ask click upgrade - when ask Insert the UPGRADE KEY, when you are finished you have a full installed OEM UPGRADE - and Activated.
I'm not sure if Microsoft still has this info listed on the How to site... but it is listed in the Manual when you purchase a Full Retail OEM UPgrade disk from ( Walmart, BestBuy or any other store that sells RETIAL OEM UPGRADE Sets.)
This UPGRADE method has been in practice for several years and is still 100% functional in Windows 7. Many sites say this is ILLEGAL but MS posted this info to Beta Testers many yrs ago. Sample back in 2000 - instructions were: Installing a Windows XP Pro or Home Upgrade CD without a Previous OS installed.
Begin the windows install as if it was the full version, during the install you will be prompted for a previous operating system, at his point put your old operating system CD in the drive and browse to the I386 folder (for Windows NT or 2000), WIN9X folder (for Windows ME), or WIN98 folder (for Windows 98). Click ok, the windows upgrade will confirm this is a full version and continue with the upgrade (after you replace the upgrade disk).
Not that I'm aware of on Activating with Orbit30 ULoader 8.0. he has to get it installed first. I also see then next question ask and not sure if the 1st solution. bought OEM and failure to install after burn... post by Blockie then he said he does not know who to mount. Two every different methods and if the DOWNLOAD IS CRAP NOTHING WILL WORK. WHICH DOES HE REALLY WANT TO DO?
