  • Windows 7 product key used accidentally twice

    Hello

    When installing Windows 7 on my laptop, I accidentally used the product key and the media of Windows 7 for PC to another Member of the family. Oddly, Windows on the laptop and is successfully activated remained activated on the first PC. In any case, I now reinstalled Windows 7 on the laptop using the product key and the media that accompanies it. My question is, Microsoft, after a period of time, will disable Windows 7 on the first PC if they detect that I used the product key on another computer (even if it is only in use on the first computer again now)?

    Thanks for any help,
    Dan

    On the first PC, I used the 'Change product key' option to re - enter the original product key and activate Windows again

    On the laptop I reinstalled from the brackets provided with the laptop (no need activation).

    Should - this to say that the first PC will continue to operate without the risk of turning off now?

    Well, they use their product keys properly attributed and are activated with them - that logic dictates that you should be fine now.
     
    This does not mean that sometime in the future, you might have another issue that requires him to become disabled, but as long as all the paperwork and the numbers are a match - the worst case are a phone call to straighten.

  • Can I use an old product key to activate another windows 7?

    Recently, master of my old laptop broke down and I bought a new laptop. However all data and files I need are still in the old hard drive so I want to continue to use the old hard drive. (It is also bigger than new btw: p)

    Probably because of the double-system(Windows 7 together with Ubuntu), I can't start Windows when I directly connect the old hard drive on my new laptop.

    Now, I want to know if I could format the Volume of C of the old drive and re - install Windows 7 because I'm afraid that I can't turn it on again. Moreover, it is sold at retail Windows 7 Professional.

    Can someone help me with this? Thank you very much!

    If it is indeed a complete Windows 7 Pro commercial license, then you should have no problem of reactivation in the new machine - however, there may be problems with the drivers and you should check the Web site of the manufacturer for the appropriate drivers for Windows 7

    You may need to use telephone activation.

  • Windows anytime upgrade, the product key is not valid

    My laptop is with pre installed Windows7 professional edition, and I have a new product key WAU (Home premium-> NEC) in hand. When I tried this product key in the Express Windows upgrade process, I received a message "product key is not valid.

    Is the installed version must be exactly the same with the WAU product key pack? I think of my installed Professional is an advanced version of Home Premium. Why not the product key be compatible?

  • Windows XP Setup will not accept my product key

    I am re-installing ona XP laptop, but the installation of Windows XP will not accept my product key. I have an OEM of a Dell PC product key that is no longer functional, and a update product key which is not null else, neither of which works.

    I can't even do the installation to achieve the activation step.

    Link to the entire conversation:
     
    Huh?
    • You have a Dell system, and with this Dell, you have a product key for Windows XP (edition?) - it would be an OEM key be used with an OEM installation CD.
    • You seemed to have bought (where?) a copy of "Retail" / license for Windows XP (edition?) - which would have its own retail product key to be used with a retail installation CD.
    What does not work:
    • using the CD to retail with the product key OEM on Dell machine sticker
    • by using the product key from retail with OEM installation media which might come with the Dell printer
    • have an installation CD OEM with an edition of Windows XP (Home and Professional vs Media Center 2002 vs Media Center 2005, etc.) and you try to use the product key OEM for another edition of Windows XP (Home and Professional vs Media Center 2002 vs Media Center 2005, etc) (editions must match, House can is complicated in this grouping too.)
    • have an installation CD retail with an edition of Windows XP (Home and Professional vs Media Center 2002 vs Media Center 2005, etc.) and you try to use the product key from retail sales to another edition of Windows XP (Home and Professional vs Media Center 2002 vs Media Center 2005, etc) (editions must match, House can is complicated in this grouping too.)
    So is that what you are trying to do?  Why did you buy the CD/product key for sale at retail and the editions correspond?
     
    If you're not at the point where you will have to enter the product key - why do you think that the product key is the question? Hah

  • Satellite C870-1JV - how to get the product key of Windows 8?

    Hello people

    Is there a way to find the product key windows 8 that was originally installed on the laptop that my laptop is not the windows sticker anywhere. I reinstalled windows once I deleted the partition by accident and now its asking me for the product key which I do not know.

    As far as I know, product key used on the original recovery image can be used if you use the version of the OS. Even with the key to the sticker, you cannot enable clean version.

    If you want to have the original version of Win8 (Toshiba recovery image) you must order the Toshiba restore disk and you can do it on https://backupmedia.toshiba.eu/landing.aspx

  • should I have the product key to upgrade xp to vista

    My wife son died and she got her computer but no cd has no product key for xp install.do, I need a upgrade product key to custom computer Vista.the built.don't where he is a few years old. Thank you

    Just create an Image backup of XP (before you upgrade) on an external USB drive. Then, whenever you may need to reinstall just Vista restore XP using the Image backup.

    (I think you'll find that Windows 7 is a better choice then Vista in the transition from XP to a newer version of Windows).

    Also if it built the computer then you will find the product key using a key finder utility. Download and run one of the utilities listed below.

    Belarc Advisor: http://www.belarc.com/free_download.html
    (He did a good job of providing a wealth of information.
    Displays your Windows XP, Vista or Windows 7 key.
    However may not detect a key to office, then try one of the other two listed below for office key).

    and: http://www.magicaljellybean.com/keyfinder.shtml

    One final note: after you upgrade to Vista or Windows 7, you will have to install the device drivers. Go to the web site support motherboard manufactures, locate the correct mother by part number, download the appropriate drivers for Vista or Windows 7 to a folder, copy it to a USB flash /thumb. Then install after the upgrade.

    Hello

    You should find an application on your laptop called Recovery Media Creator - this will allow you to create your own installation media 1 set (on disk or a usb flash drive).  See link below for more details on how to do this.

    http://support.HP.com/us-en/product/HP-envy-X2-11/5296226/model/5336701/document/c03481733

    The product key used to activate Windows 8 is stored encrypted in the bios chip and will automatically be read if you use your recovery media to reinstall Windows.
