How to get Windows 7 Pro OA Key

This question is not answered


My laptop recently crashed trying to uninstall 'Dell Data Safe Local Backup'.

With no support, I have decided to try and fix my laptop, which I believe still has the data in it.

What I think is that I will be able to install a fresh new copy of Windows 7 Pro, using a downloaded legal version of the Windows7.iso from Digital River, and then use the Windows 7 Pro OA Key.

The problem here is that the key has now faded out.

Also, the Reinstallation DVD that came with my Dell Vostro 1520 doesn't seem to be detected in my laptop, and really is no help to me.

Can anyone help me out here?

Can I ask Dell, if they can provide me the Windows 7 Key that was shipped with my laptop?

OR Can they ship me a DVD that can reinstall Windows 7 Pro on my laptop?

Thanks and Regards,

  • Neither Dell nor Microsoft track license keys, so neither of them will be able to supply it.

    Without the license key, you will need to use a Dell-branded installation DVD.  You can borrow one, buy one on eBay, or contact Dell to order one.  If you are in the US, you can request one here (if under warranty; out of warranty or outside of the US will have to call Support):

  • Hi,

    Thanks for the reply.

    In the past, when my laptop was still working (when the hard disk hadn't crashed), I tried to reinstall the factory version of Windows 7.

    The Reinstallation Disk couldn't get detected. 

    I had purchased Windows 7 Pro with XP Downgrade option, and so had two disks.

    However, even the factory version of Windows XP wasn't getting detected.

    Is it possible that the reinstallation disk that I procure from eBay or Amazon or my friends or Dell may not work again?

    And if it works, will the Windows copy be valid?

    My understanding is that OA version of Windows on laptops don't need license keys to get validated at the time of install, or even after it is installed, because authenticity of Windows is kind of embedded in the laptop itself.

  • If there is a problem with your CD/DVD drive, then no, it won't work again.

    "And if it works, will the Windows copy be valid?"

    Of course.  This is Dell's official method of restoring an OS without using built-in recovery utilities.  The Dell DVD will not require a product key to activate.


  • My DVD drive has no problems.

    I was able to run other CDs/DVDs in it and they were getting perfectly detected.

    Is it like the system was out of warranty period and that is why the DVDs didn't get detected?

  • "Is it like the system was out of warranty period and that is why the DVDs didn't get detected?"

    No, that is not how it works.  You probably just had bad media or a bad DVD drive (there are some issues that affect the drive ONLY in the OS or at the BIOS level) ... you need to also make sure you choose F12 during POST to select to boot to the CD/DVD.

  • Thanks.

    I will try to reinstall using the Dell Reinstallation disk.

    Any idea how much it might cost to purchase it from Dell?

  • And will a DVD designed for another line of laptops like Latitude or Inspiron or Studio work with Vostro?

  • And will a DVD that is designed for Inspiron or Studio or Latitude work with my Vostro 1520?

  • Any Dell DVD should work.

    I've heard prices anywhere from $20-$40 for replacement media.

  • See Windows Reinstallation Guide/A Clean Install of Windows 7: d

    Firstly are you trying to install Windows 7 within the Windows XP Desktop or the Dell BIOS? If within the Desktop try booting from the DVD via the Dell BIOS, this removes any "Windows XP" issues from not detecting the DVD in the DVD drive. Moreover System Locked Preinstallation Activation sometimes fails to work if installed outwith the Dell BIOS.

    If you cannot read the Reinstallation DVD from the Dell BIOS then your DVD drive may be malfunctioning and you must use a bootable USB. The Windows Reinstallation Guide/ A Clean Install of Windows 7 instructs clean install using a Windows 7 retail .iso with system Locked Activation thus overcoming the issue with faded COAs.

  • If you have access to another computer, you can create a bootable Flash drive using your Windows 7 Reinstall DVD.

    You will need the Windows 7 USB/DVD Tool, which is free from MS. It's simple to use.

    You may need to use a free utility, such as ImgBurn, to extract the ISO from the DVD, although you can try to create it from the DVD first.

  • Thanks for the reply guys.

    What I did is I downloaded the Windows 7 Professional 64 Bit version iso from Digital River and then created a DVD with the tool suggested by CATILLEY1092.

    I booted from the DVD drive, and it detected the DVD. I did select the option 'Repair My Computer', which fixed the 'Master Boot Record' (MBR), which really got disturbed while uninstalling Dell DataSafe Local Backup.

    I am so happy that I have been able to run Windows 7 as it was before it had crashed. Big SmileBig SmileBig Smile.

    The first thing I did was to extract the Product Key and the Dell OEM Key from the Windows Registry and keep in in a safe place.

    Now I want to do the following.

    1) Upgrade the Operating System to Windows 7 64 Bit.

    I had bought my Dell Vostro 1520 as 'Windows 7 Professional 32 bit with XP Downgrade Option'.

    I know that I can run only one version (32/64 Bit) of Windows 7 on the same laptop.

    What I intend do is

    1) Revert back the OS to Windows XP SP3, as it is still preserved in my C:\ Drive.

    2) Upgrade XP SP3 32 bit to XP SP3 64 bit.

    3) Then install Windows 7 64 Bit, as I think it can utilise the same OEM key from Dell.

    My questions are :

    1) Is Step 2 really necessary?

         If yes, how can I get XP SP3 64 bit iso? Is it available to be downloaded just like we have Windows 7 iso from Digital River?

    2) Will my OEM key really work with XP SP3 64 Bit?

    Thanks and Regards,


  • XP 32 Bit and 64 Bit installation is not necessary, you are wasting your time installing an Operating System which is reaching End of Life in 4 months (twice). Moreover XP 32 Bit and XP 64 Bit product keys are not interchangeable although the COA is valid for either. Also as you have manually installed Windows 7 32 Bit with the Dell Reinstallation DVD the recovery partition for the Windows XP installation will likely fail to function. The recovery partitions always fail to function after system partitions are changed or any OS is manually installed. Finally you cannot download a Windows XP 32 Bit or 64 Bit .iso legally as Microsoft never provided one outside of TechNet/MSDN subscriptions.

    You are better to simply clean install Windows 7 64 Bit directly, for details in doing this see Windows Reinstallation Guide/A Clean Install of Windows 7: 

    The backing up of the product activation in Step 2 within your 32 Bit Windows 7 installation can be applied directly to the 64 Bit installation (Step 11b recovering the product activation). I don't see why you want to install Windows 3 times opposed to just once.
