    Hmmm, I've upgraded at least 5 times running setup.exe from the root of the iso and it has worked perfectly each time. I get the same result as if I had upgraded via Windows Update.

    I just finished upgrading a Dell laptop from build 10122 to 10240 last night running setup.exe from the root of a flash drive I created using Rufus and a 10240 ISO I also created using the ESDtoISO tool. Worked fine, no problems.

    I'll try the one under sources next time and see what I can sport for differences in the install.

    It's really strange. I had not problems upgrading two computer with 8.1 Pro to RTM with my ISO. It's just the one with Media Center that does not want to upgrade.

    I tried both the setup in root and setup.exe in sources, both with the same results.

    When It succeeded on the other pc's, immediately after starting setup.exe I get a windowed page with upgrade questions. However when I start setup.exe on the Windows 8.1 pro with mediacenter I get a full blue screen stating 'setup being started" and afterwards the partition selection and only the option to do a clean install.

    My windows 8.1 installation is pretty standard, I even removed some programs to make sure that is not the problem. No succes, just don't want to upgrade.

    Maybe it has something to do with my disk ?

    Problem Solved

    Based on the comments I used setupprep.exe in the sources folder and this time the upgrade started without problems.

    Thanks for the feedback.

W10 Insider Prev upgrade to Win10 full vs of W7/8 upgrade to W10
Read somewhere that the latest Win 10 Insider Prev will be upgrades to Win 10 full when it is released. A good idea to install this sooner rather than upgrading Win 7 / 8.1 to 10?
