Product key can be used again

Hi I would like to know if I have windows 8 and wanted to downgrade to windows 7 Home premium, I have 7 is installed on the laptop I was able to use my laptop product key and use it to install windows 7 on my desktop?

Hello

No.; You can't use it on another PC if it is preinstalled on your laptop.

If the laptop/computer came with preinstalled Windows operating system (Dell, HP, Acer, etc.), this product key provided with your computer/laptop to the OEM license preinstalled and is not transferable.

OEM license/product key (systems of operating pre-installed on Dell, HP, etc.) is related to the first machine it is installed on and dies when dies of this machine.

Only retail Operating System license that you buy and install yourself, are allowed to be transferred to another machine.

And retail licenses also can be installed on a machine at one time.

See you soon.

  • Windows 7 Home Premium OA product key can be used only with the recovery disk?

    I bought an Acer laptop, he arrived with Windows 7 Home Prem OA sticker behind. I've heard, if you want to reinstall windows, we can only use Acer Recovery Disc for this product keys? Is this right? Can I use any other Windows 7 Home Prem CD and install it and then I put the product key of the laptop, it can also?

    Thank you

    You can use a disk from Windows 7 Home Edition Premium authentic retail.

    There is no need to separately download OEM or retail of Windows 7 RTM installation DVD ISO, as the release of Windows 7 installation can be easily converted using simply the correct product key (for example OEM_SLP product key can convert an installation of Windows 7 at retail in OEM version), as issued by the OEM product keys has a different basis of the retail product key. For ISO of DVD images, the only difference between a Windows 7 RTM retail ISO and ISO of OEM of Windows 7 RTM is in position of EI.cfg file [channel], which specifies the sales channel to retail or OEM.

  • Cannot activate Windows, the product key already in use

    Original title: product key already in use.

    Recently, my computer crashed (power).  Try to avoid problems with my hard drive, I bought the same computer exactly on the line.  I installed my old hard drive on the newest computer and all is well... Except, when trying to activate my Windows Vista Ultimate OS I get the error message "The key of product already in use" Microsoft site confirms that the product key is authentic, but still will not let me activate.  All solutions?

    Your old computer had a "Retail" or "OEM" of Windows installed version?

    OEM versions are related to the 1st motherboard they are installed and can not be activated on another motherboard. The only exception is the 'mother' is exactly the same make / model / part number as the original motherboard.

    Commercial versions can be moved from one computer to another without problem except that the the phone activation may be required.

    This happens often because he sees it used already on your own computer (it can not make a difference).  If you mean that you can not activate automatically, try to do it manually:

    To activate manually, go to start, search, and type in slui 4 enter.  Enter your country and press Next.  You will be on a screen with a phone number and a bunch of codes below.  Dial the number and browse automatic guests until you get to a human being.  Have your handy product code because it will be asked.  Explain the situation, but it's the same PC and only installed on this PC.  They should give you a code to enter on this screen to activate Vista.

    I hope this helps.

  • This product key cannot be used to install a version of windows 8

    I bought a new computer dell laptop and you want to install windows 8 again. It came with Windows 8 Core with is the unique language of 64-bit

    I downloaded the windows Upgrade Wizard 8.

    Then I discovered my product key with keyfinder.

    I ran the upgrade wizard then copied the product key and it shows the message - this product key cannot be used to install a version of windows 8

    I ran windows Update and it allowed me to download the update, which means my Windows 8 is authentic then why I am not able to install windows 8.

    I'll be able to install the kernel of windows 8 with Windows 8 iso pro?

    Hello

    Thank you for contacting Microsoft Community.
    Windows 8 that came with your PC is OEM type license and is one you want to install the retail type license. Two licenses have different installation keys, so commercial version will not accept EM key and vice versa.
    In addition, Windows 8 Pro key is different from Windows 8 "Core" key. You may not use the button either.
  • Product key for win 8 doesn't work no-error: this product key cannot be used to install a copy of windows retail.

    I bought a copy of windows 8 for the upgrade to windows 7 from the Microsoft store. I need to reinstall the hard drive on this machine, but when I download the installer of windows 8 on another machine to try to create a bootable USB I get an error message when I put in the product key (which I paid for) who says: this product key cannot be used to install a copy of windows retail.

    How can I get this problem?

    Hello

    Thanks for posting your query in Microsoft Community Forum.

    Ideally, there are two types of product keys: key to retail version key upgrade and full. The key to upgrade is used to upgrade the version of the operating system when you have the lower version of the operating system already installed on the system, for example, if you have already installed Windows 7 system, you can use the upgrade of Windows 8 to upgrade (override) currently installed Windows 7 to Windows 8. This product key cannot be used to download the installer of Windows 8 and create a bootable for installing Windows 8 from scratch.

    However, the key of the full version allows to download the installer of Windows 8 and create a Windows 8 boot disk to install a full version of the operating system.

    According to your description, you have reinstalled the hard drive on your machine and want to install Windows 8 by creating a bootable. Thus, you will always have the above error message while downloading executable files for Windows 8.

    There are two options you can try to install Windows 8 on your system:

    • Replace the key with a key to the version upgrade complete on the Microsoft Store and follow the procedure as you said in your post. You will not get the error message given.
    • If you have the Windows 7 installation media, you can try to install Windows 7 on the reinstalled hard drive. After activating this operating system, you can try to upgrade to Windows 8 by using the product key that you have already purchased.

    Hope this information is useful. If the problem still persists, please post back for further assistance, we will be happy to help you.

    Hello

    The product key you use to install could be a volume license key, you can contact your network administrator to download the iso from this site http://msdn.microsoft.com/ and install the W8. The W8 will be key during the installation or is installed with the default key that will work for 30 days. If it is installed with a default key, you can change the product key with the suite of measures

    -Run as administrator command line
