Difference on the installation disc and computer product key

Hello

Why is the product key on the different installation for Windows 7 Ultimate disc from that on my computer that verifies a genuine copy was installed?  In other words, the product key on the installation disc has a combination of letters and numbers.  However, the product key on my computer that verifies that you have a genuine copy of Windows 7 Ultimate installed has only numbers.

Thank you in advance.

The product ID is never really entered into the computer, what you have on the label is a 24-bit coded version which decodes the installation process to form the product ID.

If you have already built a system by entering the 25 character key, you will see a small break after entering the key. This is the decoding of the key system and then check the type of product with the version of the software being installed.

Also, be aware that if your system is a large manufacturer and shipped with Windows preinstalled, then the encrypted key can not match the label. If you use a utility such as magic jellybean keyfinder on a system, it can retrieve this key encrypted in the registry. This key is different from the label, because all systems supplied by the manufacturer with a particular version of Windows will have the same key. This avoids having them to enter a key on all of the PCs they do individually and do not have to be authenticated on the line.

    I need to activate my windows 7 Home premium and when I look at the bottom of my computer product key essentially disappeared... What can I do to get my product key?

    Option 1: You will need to invest in a new license.

    Option 2: If your computer comes with a recovery partition, use to reinstall Windows 7, it will exempt the need to have a product key.

    Option 3. Ask a recovery disk set from the manufacturer of your computer and use it to reinstall Windows 7, it will be exempt from the need to have a product key too.

    New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

    If your recovery partition is not available or damaged, you must contact the manufacturer of your computer, and request that a defined recovery disk you can use to reinstall Windows 7. They could practice a small shipping and handling.

    ------------------------------------

    This is how the recovery partition is available for the most popular brands

    For Dell, press CTRL + F11 directly after switching on the device

    For HP, press F11 directly after switching on the device

    For Toshiba, press and hold "0" BEFORE and during the power upward

    For Acer, press and hold ALT + F10, as soon as you see the logo

    For Asus, press F9, as soon as you see the Asus logo.

    Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"

    Do you mean that you have downloaded the Epson driver?

    http://www.Epson.com/cgi-bin/store/support/supDetail.jsp?BV_UseBVCookie=Yes&infoType=overview&OID=209709

    Try using the wizard adding printer in the Control Panel, printers. In the wizard, select EPSON under manufacturer. If you don't see your printer in the list, click the Windows Update button. It will take several minutes (about 20) be patient, Windows updates the list. You should see a hard drive activity during the update.

    If that wouldn't work, try to run the System File Checker:

    I can not forward a more unless I can access the product key.

    Really need help here

    Hello Lauren,

    Thanks for posting your question in the Microsoft Community Forums.

    If your computer came pre-installed with Windows 8, then using the recovery disk don't ask for the product key. The product key of Windows 8 on new machines is now integrated into the motherboard. It uses the Secure Boot technology.

    If the user has to reinstall the operating system on a computer with Windows 8, the installation process automatically captures key software product of the motherboard BIOS without input from the user. If you have an OEM computer that is preinstalled with Windows 8, then you must contact the manufacturer of the computer that the computer broke down recently so that they can help you.

    If your computer came pre-installed with Windows 7, then you must install Windows 7 first and then upgrade to Windows 8.

    Response with the State of the question and we will be happy to offer you our help.

    I have already indicated at the beginning of this answer on how to access the info about the recovery Partition, if you have one (what you should do)

    How to get Vista recovery Media.

    There is no Vista free download legal available.

    Call Dell and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

    I lost my laptop computer restore disc and it is no longer supported by the manufacturer. Can I use the installation disc for my desktop with my laptop serial number?

    My title says it all. I have an old HP laptop that they do not send to restore the disc more (I don't know yet I had one; his old laptop from my brother) and I have an installation disc for my new PC. I have a Windows XP Home edition SP2 installation disc. However, as the hard drive of my laptop broke down, I don't know what version of windows it was. I think it should have been an OEM version and the sticker says it was Windows XP Home Edition.

    Now, anyway I tried to install my installation on laptop computer disc, offering series of laptop computer but now it asks me to activate. Will it work if I activate it?

    Thank you

    Unless you are lucky enough to know someone who has a generic OEM drive, which you can borrow, I don't see a practical solution for you.  I advise you to spend the money to buy one, even if you could find one to buy from a reliable source (not eBay!).  Although a generic OEM disc should work with your product key, there is no guarantee that it will work with your product key.

    If your laptop can be retrieved through a restore partition, and you can't borrow a disc that will work with your product key, then you have pretty much exhausted all reasonable or practical options.

    I finally did! I borrowed a copy of a generic OEM drive, through activation and it is!

    Thank you much for the help...

    Now I've done could you help me more? Say now, I returned the drive OEM back (don't want to make an illegal copy) and want to be able to use my current system installed to generate a system disk that will allow me to avoid all the problems I've had up to now. What would you recommend? I've read a few articles on other forums (I did some research!) but is a little confusing. I hope you could help.

    Thank you

    Call the manufacturer of your computer tell them the exact situation.

    1. ask if they can help you with unreadable product key.
    2. ask for a set of recovery disks. The cost of a set is minimal, and it is worth the money spent.
    3. at the same time, ask a technician to learn you how to access the recovery Partition from your computer and how to make the system using the partition recovery.

    #2 and #3 methods do NOT require the use of product key. ****

  • What is the difference between the sotware disc recoververy disc and

    What would be the difference between a disc of Windows 7 software and a Windows 7 recovery disk?

    If you purchased Windows 7 preinstalled on a new computer, the recovery disk is used to restore your computer with the operating system installed (Windows 7) and other applications packaged in its original factory condition. Thus, it will be just like when you bought it.

    A Windows 7 installation disc is simply the installation for the installation disc or reinstallation of Windows 7. This often requires that you reinstall things like other applications and drivers separately after the installation of Windows 7.
