Windows 7 version "upgrade" RRS feed

  • Question

  • Hi All.  Have a number of Windows 7 Pro laptops in the field that I would rather not have to do a full reimage if at all possible.  Was checking into upgrading the version of Windows 7 to Enterprise.  I've looked into options with "unattend.xml" and found one section named "UpgradeData" and set the value to true.  I read on TechNet that this is the only section of the unattend file that needs to be setup for an automated upgrade.

    So, then I move on and attempt to test with the Win7 Enterprise DVD extracted ISO.  I've attempted to run this from the FullOS and from WinPE.

    FullOS:  Run setup.exe /unattend:<name of unattend file>
    Result:  Tells me image not found.  If I use the "/unattend" switch with the "/installpath" switch and specify the image, get the same error.  If I just use the "/installpath" switch, I don't get the error which tells me it may be something with the unattend?

    WinPE:  Run setup.exe /unattend:<name of unattend file>
    Result:  Installation starts in "installation" mode and requires user interaction.  You can't even choose upgrade.

    Here's the unattend file:

    <?xml version="1.0" encoding="utf-8"?>
    <unattend xmlns="urn:schemas-microsoft-com:unattend">
        <settings pass="windowsPE">
            <component name="Microsoft-Windows-Setup" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    The ultimate goal is to fold this into a task sequence and add TPM activation/encryption steps (which I already have working).  Anything I'm doing wrong with the above methodology/configuration?

    Thanks for any help.
