    How do I verify that was done? When I installed the RC, I wiped out all the pgrms that I had on XP. Will I need to follow the steps above or will I follow the normal upgrade steps. Thanks for your help Robert!!!

    Let me rephrase: If you can no longer load/start/run Windows XP on your machine, just follow the guide as presented, and everything will be okay. :)

    Glad we've cleared that up. Now how about we keep on topic?

    Are OEM full installs available yet anywhere? I keep forgetting to look around.

    Will this work with the OEM versions as well or only the full retail?

    OEM versions will work just as well.

    I want to go from RC 32 to Win7 Home Premium 64 using an upgrade DVD. Do I have to go back to Vista and then clean install, or will the trick mentioned here work?

    You will have to perform a clean install to migrate to 64-bit (good choice!). Combing x86 and x64 files is not supported.

    Will this procedure work with an oem (system builder's) disk of Win 7 or must it be an upgrade disk?
    • Awesomesauce Lulz

    If the system builder's disk is a standard OEM copy, which has not been modified by the OEM, then yes it will work fine.

    Can we be certain that upgrading this way will remove the RC expiration date of June,2010?

    It is certain. The expiration date is determined by the activation server's analysis of your product's key; RTM keys have no expiration date, while the limited list of RC keys are all flagged to expire on 6/010.

    step 4. You may not have hklm (=keyroot instead). search for Software\Microsoft\Windows NT\Current Version string in registry and you'll find the version name.

    First of all, thank you SO much Robert! I've been walking around with a flashdrive that has the Win7 install binaries on it and was hoping to upgrade my tablet (currently running 7100) to the RTM; this should let me do it!

    On a side note, why does upgrade from Vista work? Vista is build 6000...

    @Kenny C: You can not do an in-place upgrade from XP to Win7; at least, not normally. Technically, if you lower the MinClient value (from the instructions) to 2600 (the build number for XP) it *might* work but I absolutely do not recommend this.

    However, you will be able to use your upgrade disc to install Win7 - you'll just have to do a clean install over XP (which usually means reformatting). Put in the disc and boot off it, select Install. It should detect your XP copy and allow you to install Win7, but it will require that you do a clean install rather than an in-place upgrade.

    Thanks for this guide. Do you also have an idea to downgrade the RTM Ultimate to Home Premium ? Would be cool as well for many people (yeah I know that MS won't support it now....). Thx !

    Scotty: You can try setting the minclient version number to 7600 and performing an upgrade, but I can't guarantee that "upgrading" an RTM to an RTM will work.

    Thanks Thrax, but id didn't work. So I have to do more research....

    News: If your on the RC you can still upgrade with the E version. You just can't upgrade from vista with E Version.

    Right click the file, hit properties, and uncheck "Read only." That should fix the problem.

    Can I use a Windows 7 Upgrade disk, or do I need to have the Full version for this to work?
