I installed a copy unregistered XP, but I have a valid product key XP: how to register in order to install MS Security Essentials?

I get the following message when trying to install MS Security Essentials:

"Windows failed the genuine validation. ..."

Win XP has been installed using a copy XP without registration.


I have a 'valid product key' (the label at the back of the laptop).

How can I make "authentic"?

  • How install to reinstall Windows Vista without a disk on Ubuntu Linux (although I have a valid product key)?

    I have an Acer Aspire 3100 computer laptop comes with Windows Vista, I am not on the number of bits, sure that the processor in this system supports 64-bit operating systems. I was curious to know if there was a way for me to download Windows Vista from Microsoft online and burn it to a CD or a DVD if I have a valid product key supplied with the system. Is it possible to do this? Thank you.

    You can not download Vista.

    In this case, you may be able to buy Acer recovery disks, if you have not created some when you first the computer.

    If you can borrow a Vista DVD (a copy retail, not supplied by manufacturer), you can reinstall since using your product key.

  • I can't update windows until I reinstall windows vista service pack 2 CD but I do not have the CD. I have just the product key. How can I reinstall it with the key.

    I tried to update to windows, but get error 80070490 that says I have a corrupted file (CBS Manifest) that is to be updated... so I check the error and it says to uninstall windows and reinstall using the dvd... but I don't have the dvd for windows vista service pack 2... I have the id... product help, my pc is done to the breakpoint until I make updates! I tried Fix - It, and it says error can not continue... I ran to day thought advise that I could upgrade to windows 7... but apparently so that I can fix the problems of windows, I'm stuck. Thanks for any help!


    Error code 80070490 claims a repair upgrade install, not an uninstall and clean reinstall.


    If you receive the Windows Update 80070490 error, it means that a file (CBS Manifest) that is needed to install updates is corrupt. To correct this problem, you will need repair Windows. Repair Windows will not damage your personal files or the programs that are installed on your computer.

    Have you tried the other option for system update readiness tool in the link I just gave you?

    The System Update Readiness Tool for Windows can correct some conditions that cause Windows Update 80070490 error. You can access and run this tool by reading this Knowledge Base article on the Microsoft Web site.

    And you need a DVD of Vista from Microsoft to do a repair installation upgrade according to the instructions, NOT the normal manufacturer's recovery disks.

    You will need to borrow a Microsoft Vista DVD from a friend or working knowledge.

    Here's how a repair upgrade installation:

    "How to perform a repair for Vista Installation"



    And if you can't get a loan from a Vista DVD from Microsoft, you may need to do a reinstall of Vista:

    You can contact your computer manufacturer and ask them to send you a set of recovery disks.

    They should do this for a small fee.

    To reinstall Vista using their recovery disk/s, you start from the 1st recovery disk they provide and follow the manufacturer's instructions to reinstall:

    You need to change the Boot order to make the DVD/CD drive 1st in the boot order:

    How to change the Boot order in BIOS:


    "How to replace Microsoft software or hardware, order service packs and replace product manuals.


    And if you have never received a recovery disk when you bought your computer, there should be a recovery Partition on the hard drive to reinstall Vista on how you purchased your computer.

    The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

    Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

    Ask them to the proper key sequence.

    And if you do not score a manufacturer of recovery on your hard drive, you should be able to make your own recovery from her disks to reinstall the operating system.

    Go to programs > name of the manufacturer of your computer > then their system or recovery tools software topics for them, depending on how it is formulated.

    If you can't find any reference to it, contact the manufacturer for advice on how to make these recovery disks.

    Some manufacturers have more available Vista recovery disks.

    If this happens, you may need to try this instead:

    You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

    Other manufacturers recovery DVDs are should not be used for this purpose.

    And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

  • I have a valid product key Windows 7 - but no disc upgrade. Any options?

    Bought a client computer back.  Was able to restore the original Vista operating system.   I have a Win7 Home Premium COA key attached to the Tower, but no disc to complete the upgrade.

    Seems a waste of money to buy a package to upgrade when I already have the key.

    What are my options?

    HP 9517c desktop

    currently under Vista

    Thank you!!  Don

    If the key of Windows 7 is not an OEM key, it should require only a Windows 7 DVD for installation work and be legal.  See if you can borrow an installation DVD for someone who already has Windows 7.  Of course, the key will allow only Windows 7 Home Premium to install.  The DVD will ask if the installation is an upgrade or a full or custom installation (I forgot just how the question is asked) then simply use the key of the sticker.

  • I just installed Windows Defender, but he does not see my Windows XP Security Center. I had to install Microsoft Security Essentials for Windows to see any antivirus. Why?

    I removed Bitdefender because it slowed my computer down a lot. I then installed Windows Defender and updated and scanned the computer (no problem) and said it was "protect my computer". But the Windows Security Center does not see any antivirus, until I installed Microsoft Security Essentials. Why? And are two antivirus programs now runmning together?

    Microsoft Security Essentials need to uninstall Windows Defender when it is installed. If youshould not uninstall via Add/Remove programs. See the following topics:

  • Need to reinstall XP but have lost my product key

    I have a windows computer that is so old that, until recently I only ran from 98SE to this topic.  A few years ago, I bought XP - just before XP exploded the market, actually.  When I installed it, I discovered that the only programs I've used with no matter what regularity still existed, a couple who worked in the BACK (!) and the other who would not run in XP.  So I went back to 98SE.

    Recently, I bought a Macbook Pro.  I have an emulator on BACK, so I run now these two programs on the Macbook.  And I have a Mac program, which replaces the one that did not run in XP.  But (1) I need the Macbook to the old Windows of the network computer, and it doesn't seem to work with 98SE; people on various forums suggest that it will be easier with XP.  (2) I downloaded a new program that does not run under 98SE, but works on XP, Vista and 7.  (My old windows computer is too low to run whatever happened to XP.  Even XP stem it.)
    So now I want to reinstall XP.  I was barely in the process when the message came to enter my product key.  The problem is that shortly after the first installation, I put the disc in a box, without getting into account that the product key is on the original cardboard jacket (or whatever XP came in--I don't even know).  I've looked everywhere and can't find it, and apparently I copy down the key to product no more.
    Y at - it * all * way to reinstall?  Or get my product key for Microsoft (I register XP when I installed it first)?  I can't reach tech support tonight, I get an error message.
