Install Vista Upgrade Without Preexisting XP

Posted by kdawson on from the loophole dept.

Johannes K. writes "It has previously been claimed that to install Windows Vista from an upgrade DVD requires having Windows XP installed on your computer. DailyTech reports on a workaround: no previous version of Windows is required at all." Anyone know whether this workaround moots the finding by LXer that during upgrade Microsoft invalidates your original XP CD-key?

  1. Instructions from the article... by james_bray · · Score: 5, Informative

    God I hate when submitters force you to read an entire article, so heres the important bit:

    1. Boot with the Windows Vista Upgrade DVD.
    2. Click "Install Now."
    3. Do not enter a Product Key When prompted.
    4. When prompted, select the Vista product edition that you do have.
    6. Install Vista normally.
    7. Once the install is complete, restart the DVD-based Setup from within Windows Vista. Perform an in-place upgrade. 8. Enter your Product Key when prompted.

  2. Alternative way to install from upgrade disc by HxBro · · Score: 5, Informative

    What you need is a copy of legitcontrolcheck.dll from any validated and activated copy of XP on a partition anywhere on your machine, then:

    1.) create \windows\system32\ on any partition you want (even extended partitions)
    2.) copy a validated 'legitcontrolcheck.dll file into the directory.
    3.) you might need ntdetect.com and ntldr in the root, (try without)

    (I've not tested this)
