  • Windows 7 Ultimate 64 k product key not valid after more than a year of use

    Initially, I bought a Windows 7 Ultimate 64 upgrade as a student version. My computer originally had Windows 98. ten years later my hard drive died, and I learned that you cannot reinstall a version upgrade. (beware of the free windows 10 UPGRADE). I bought a product key of the online Microsoft Store over one year in January of 2015. I have finally is broken down and bought the key because I was advised if I never had to do a Setup again that buying a key meant I could without any other expenditure. It seems to work fine until I recently got a message saying that my copy of Windows 7 Ultimate 64 is not valid. I called the Microsoft store and they claimed to have no trace that I already bought the product key from their part. After a few unsuccessful attempts to locate the original mail, finally, I scored. I received an email from a Laura McBride in the Microsoft Online store, with a product key and a link to a file in Dropbox. So I tried to do a repair and reinstall by using the information in the email. The Dropbox file will not download to my Dropbox, it said its too big. It will not download to my computer as it says that the .zip is too large. I'm reaching here. What can I do next?

  • Reinstallation of Windows 7 Ultimate edition, suddenly product key not valid?

    After 5 years of use, I started having trouble with my system. Microsoft Office gave errors and Windows 7 has been hard too long to start upward or too long to close. I decided to do a new reinstall of Windows 7 Ultimate. I bought the version I have in my University just now and everything was going well on the first re-setup, until I tried to install Microsoft Office only to watch him hang at start installation for far too long. After trying to solve the problems, I thought it would be better update of Windows 7 in total, well, Windows Update installation suspended installation and start-up. So I figured a reboot would help and unfortunately the o/s started showing the same symptoms he had before as I wiped the drive clean. I erased the disc again and tried a new installation, but this time all of a sudden, my product key was invalid. Again, it is a purchase copy, should I call Microsoft?

    As a reminder, I have no o/s on the system other than the installation just run by the disc, now it is stuck on the main screen product because he accepts it.

    You should be able to install without a key and start the 30-day grace period.

    This would then allow to enter the key after installation. However if that dialogue initial report, the key is invalid what you type does them not. At this point, there is no that verify that the key is correctly encrypted is the right key for the version of Windows that you are installing, it does not check with Microsoft for the key abused later, may not have a network connection.

    Make sure that the characters are correct

    B C D F G H J K M P Q R T V W X Y 2 3 4 6 7 8 9

    Some ambiguous characters do not serve but B and 8 can be confused because of the size and the tail of the Q is so small it looks like O which is not actually used

    Is it an upgrade license?

    However, the requirements for the media upgrade is that you have an operating system already eligible such as Windows XP or Vista installed to use it. Since the Windows 7 end user license agreement.

    15 UPDATES. To use upgrade software, you must first be licensed for the software that is eligible for the upgrade. After the upgrade, this agreement takes the place of the agreement for the software that you upgraded. After upgrade, you can no longer use the software that you upgraded.

    So, if you are always denied, you will just have to reinstall Windows XP or Vista and let it do the verification of eligibility.

  • Windows XP Home edition has crashed - how to return WXP and use with the product key?

    Hello. I bought an Equium L20 last year and after 1 year my windows crashed due to a virus. I want to know how to get a real windows xp OS because the product under my laptop key is always saved for me and is a legitimate product but I can't get windows because it was obviously preinstalled and no CD was given to me with the package.

    How can I get back Windows to use with my product key on my WIN sticker below my laptop.


    First of all, it is very strange that recovery CD is not delivered with your laptop. It's hard to believe, but anything is possible. As you know after buying a new product, it is very important to check all orders sent with it and if something is missing, you must call the local as soon as possible and not to wait a year.

    Sorry but this key code belongs to original recovery image and you can't use it with every installation of Windows XP Home edition CD. In your case, there are two options:
    -You can buy the CD of facilities Microsoft original WXP (with the key correctly code) or
    -Contact the partner of service allowed in your country and order the new CD from recovery for your laptop model.

    All that s!

    Bye and good luck!
