  • Can I just upgrade windows 7 professional to ultimate without using WAU?

    I have a new laptop, Dell Lat E6400 with Windows 7 Pro. I want to immediately upgrade to W7 Ultimate to take advantage of Bitlocker. So, I ordered an update disk to 7 Ultimate. When I run the upgrade from CD it tells me I can't do that and that I must run the update from Windows Anytime Upgrade. Well, that asks me for a Windows Anytime Upgrade procuckt Key. NOT the W7 Ultimate Key. What can I do?

    Thanks in advance.

        If I understood your problem you could try hacking the registry like explained here:

        Make windows think it is beta or something, then it should let you do an in place upgrade.
        We did this to downgrade Windows 7 Ultimate to Windows 7 Professional, i guess it should also work for your case.
        do a backup beforehand though

          have you prepared your partitions for bitlocker?

          See below,...

          essentially - you must have a 1.5GB partition, at the start of the disk, and then have your C: and D: drives etc further down the disk...

            The URL was removed as I believe this breaches the EULA of Windows 7.

            ANY future discussion of modifying the registry to allow unauthorised changes shall result in the immediate banning of the posting member. Thank you.
