    Hi Mike

    I'm perusing this now => How best to upgrade from Win 7 home premium to Win 7 ...

    I would say a valid windows 7 professional retail or enterprise key
    Maybe an OEM key for the computer you are trying to upgrade if win7 pro was available on it from the factory. Has to do with the SLIC table on OEM computers. Torchwood or a few others, I believe could verify that knowing the make model, etc.

    ACER Aspire 5734Z
    It is old but meets my needs.
    I have a Windows-7 Pro Retail DVD and Key.
    I'm afraid to try it as I do not know if it will Upgrade what I have or Over Write what I have.
    I would just like to Upgrade.

    If the Pro key you have is a Retail, just insert the DVD on the ODD drive and run setup.exe from running Windows.

    It will reinstall windows as Pro and keep your data and programs. You will need to do the Updates.
    I recommend you use Single file with all updates - Simplix

    Quick and easy. I have done it several times.

    Keeps all your programs files settings and updates.

    Type upgrade into start search box. Click windows anytime upgrade when it pops up.

    Enter any win7 pro key ( in the picture it is the acer pro slp key YKHFT-KW986-GK4PY-FDWYH-7TP9F - this is not an oem machine , any pro key will do for the upgrade to run). It runs for a couple of mins and pretends to have failed.

    Reboot and it will complete the upgrade to pro. It is upgraded but it is not yet activated.

    Then enter your key in the system window as usual to activate.

    Job done, takes only a few mins.

    I was looking for this too. But i have 3 additional questions.
    - Will this still work now win 7 is no longer supported?
    - if you have a key, why not entering that instead of the key you mention?
    - the most important question : i have a C and D drive. the C drive is an SSD. So i put the users folder on drive D using a hard link or directory junction. that in order to make all this data fit. But my worry is that an update will change this.
    why the update? well i installed 32 GB and now i found out that it requires a PRO edition :-(

    thanks for any answer

    yes

    You can enter ANY windows 7 pro key. It must be a pro key because that tells it the edititon to upgrade to.

    It won't activate at that point. You will have to enter a valid key after you have rebooted and the edition upgrade has completed.


    So i put the users folder on drive D using a hard link or directory junction
    I don't know, I have never done that.

    Thank you for your reply.

    I think only MS knows if directory junctions will be saved since they know which files are replaced.

    You can use the command line to change the version. Windows Edition-Servicing Command-Line Options It will have to be the pro generic key Windows Generic Keys . GitHub It will reboot twice and then you'll have pro installed. I've done this on Windows server. Note that you won't be able to downgrade back to home.

    Then you'll have to activate with your retail key. If automatic activation fails you'll have to force phone activation. https://www.sevenforums.com/tutorial...indows-7-phone.
