    Hey, I'm currently using Ultimate RC, and I didn't have any OS on this computer before (no xp/vista) Can I install the cheaper Upgrade Version of Professional?

    You could try, but I don't think so. You can do both if you foillow the instructions to the letter.

    It also works for upgrading from vista ultimate to home premium. It even brought forward the fax program from Vista Ultimate.

    I am interested in doing this but I have a question
    If I install professional over the RC, will I lose the ability to change the unicode to a different language? I believe that is an ulitmate only option?

    If you're referring to MUI packs, yes, you would lose that ability. Only Ultimate can use and manage them.

    2/12/2009 Sounds very intersting got version 7100 on my computer and I must say the best since XP.
    I have ordered Win7 professional OEM
    has anyone tried your method and found problems of any kind also what would I be expected to lose program wise.I cannot bear the thought of another re format but that may be the wiser course what do guys think

    Nobody has had any problems, and you won't lose any programs because it's an upgrade.

    Finally got around to doing this on my main rig. Took 2 hours on a fast box with tons of data and worked perfectly, as expected.

    Note that an upgrade will not deal with an installation where the user files and program files are not in the same partition as the OS partition.

    What an absolute bummer. That'll teach me to be clever and move my user and program files off the OS partition.

    Hey guys I am performing this upgrade now to RTM Ultimate from RC so I did not have to do anything special with registry and such. My upgrade is progressing but I now have my screen blank and my HDDs turning like mad. I have a lot of my doc stuff and everything which I backed up before starting so I am thinking that is the reason for the hold up. Will post my results but my system drive was 120gb full out of 160...might be a good warning to those who have a similar situation to be patient.

    Will comment back in a few more hours as I think my upgrade is going to be on the longer side of things sort of wishing I had just done it clean instead =P

    Okay upgrade completed just fine I did go black screen during install...turns out when I dozed off on the couch it restarted and was sitting at the cd-key screen and the video got messed up.. I powered off the system and rebooted and got back in entered my key and boom all was good. Everything was saved and fine!

    Thanks for the write up now my brother and father can upgrade as well with their versions when I give them their Christmas preset.

    That sucks. I have my laptop with the RC set up that way.

    Finally got around to doing this, and it worked flawlessly. Thanks as always, Rob.

    Just registered to say thank you so much for posting this.

    Wasn't looking forward to reinstalling all my software & settings.

    Used the UK Student 32 bit version and it worked like a charm, and unlike a previous user it registered online.

    Thank you thank you thank you! I would like to note that many of us were in the situation where we replaced our original OS with Win7 RC completely after discovering how awesome it was. So, "upgrading" from only the RC doesn't necessarily mean we're swindling MS, we just preferred the to use the goodies earlier than MS would have us. I installed Win7 RC OVER Vista Home Premium on 2 laptops, and fresh installed over XP Pro SP3 partition on a desktop. So it would appear as if I had no originally licensed OS when upgrading when in fact I did. I think most of us are in that boat, and that this workaround shouldn't be considered problematic from a legality perspective.

    Anyways,
    Hey guys ,i found this post great and it came around at a time when i was looking to down grade from RC ultimate to home premium but im faced with a problem at modifying the registry entry . it shows only the (default) entry and not the reqd entries,so how could i go about the downgrade ??

    I have Windows 7 RC installed on my laptop. I got ahold of a Windows 7 Professional install through my University. I followed the instructions (changed the install file and registry file). I made a bootable disc using ImgBurn, restarted my computer and went through the first couple screens. The Compatibility Report tells me 'The computer started with the installation disc. Please remove installation disc, restart Windows normally, reinsert disc, and begin setup this way'. Setup doesn't run when I do it this way. Anyone run into this problem or know a forum where they have solved this?

    Is there a way to do this in Vista?
    I have 12 Vista 64 Ultimates that I want to put down to Professional, so I can upgrade to Windows 7 Professional without doing a clean install.
    I Tried the above registry tweek and it did not fool the Vista Ultimate.

    I've just used this to upgrade from Windows 7 Pro to Windows 7 Ultimate. I'd bought an Ultimate upgrade disc but when installed it wouldn't do anything other than overwrite the whole system. In this case the change to the cversion.ini wasn't necessary -just the two name changes in the registry and now it will keep all my settings when I upgrade. I'm just upgrading the third PC this way while still awaiting a call from my Microsoft reseller who's supposed to be finding out how to do it officially!

    I purchased the Home Premium upgrade disc and used this method to install it. It worked like a champ! I had the Windows 7 Ultimate RC and "downgraded". No issues at all. Thanks a ton!

    Surely if mighty Microsoft doesn't want us to update against the RC all they need do is check that we are running the RC at the beginning of an upgrade installation. Am I missing something?

    They do, which is why you need to follow this guide to circumvent that check.

    Can you use a downloaded version of Windows 7 and do the same thing?
  • edited February 2010
    The download version from Microsoft has MinClient in the .exe file used to install. It does not expose cversion.ini as far as I can tell. Editing the .exe file should work fine.
