lost activation of windows 7 when I uninstalled windows 10

I have a used laptop bought with windows 7 on it two years ago.  I went through the process of activation then and it has been very well give me all the updates.  Two months ago, I received the windows 10 icon I have my tray and upgrade to windows free 10.  I had minor problems with windows 10 so restored to windows 7.  Everything was fine until now, all of a sudden im told my windows 7 is not enabled and it will not activate. I have no product key for windows 7 and I did not find and write down the product key for windows 10 when I have I had it installed. So now I have no way to reactivate my windows 7 and 10 windows will not reinstall. I'm sure that Microsoft, intended as a client validates windows 7 (without a product registered for her key) to have free windows 10 that now will be no reinstall and now even my windows 7 is ruined for activation. Please notify. I'd be happy to either get one activated windows 7 return or a 10 windows reinstall. Thank you, James H.

By own tell you all wiping files and start from scratch?

Yes.  Obviously you should back up files that you want to keep the first.  He pourrait be possible perform an installation developed level, but given your situation with the activation of Windows 7, I would recommend not this.

This means that I would need a drive on the right.

Yes (or the equivalent files on a USB key).

I have a windows disc 10 resettlement which says I need a product key. But you are saying maybe I can live without this product key request?

Yes.

I just tried using the free windows than 10 download. It gives me a download but nothing happens when I try to "run" it. I guess that's because this isn't a new installation?

You need start from the disc to start the process.  You must be careful to install the same version of Windows 10 you had before; You can not go home Pro and vice versa.

    They do * not * do the same thing. Windows Defender is an anti-spyware program only. When you uninstall McAfee, you have p anti-spyware [protection, but no anti-spyware protection.]

    Moreover, in my opinion, McAfee is one of the worst of the available security programs.  For an anti-virus program, I recommend eSet NOD32, if you are willing to pay for it. If you want a free anti-virus, I recommend one (do not run more than one) of the following three:

    When activating my windows vista ultimate product, I get the response that the license key is already in use, let me know how to solve this problem?

    KiranS Hello,

    Judging by your post, it seems that Microsoft had technical problems when you tried to activate your copy of Vista by phone. Have you tried phoning the line Activation again?

    The normal procedure is that if the activation fails through the automated system, the call is transferred to a real person. It is the only available option if you get the error 'use existing product key'.

    I can only suggest that you try again the activation by phone and see what happens.

    This forum post is my own opinion and does not necessarily reflect the opinion or the opinion of Microsoft, its employees or other MVPS.

    If you want Office 2007 updates to appear in the installed updates again, you would need to uninstall/reinstall Office 2007 and install all the updates again.

    Assuming that Office 2007 is installed & working properly and no update is offered when you run a manual check for updates now, you might want to leave enough alone (that is, do nothing) - then see if the 2 updates for Office 2007 SP3 be released next Tuesday (a) receive, (b) successfully install and (c) are listed in the installed updates later.

    PS: The possible causes of the problem are messing with registry cleaners, messing around with the Software Distribution folder, and the fact that it was a computer refurbished when you bought it.

    4. by setting activation of Windows 7, Microsoft Office can always be opened without any problem?

    Sorry for my English is not my mother tongue. I wish I can get the answer as soon as POSSIBLE. Thank you

    Honestly, it looks that your system needs a new reinstall of Windows 7. It should reinstall applications such as Microsoft Office and drivers for devices such as your scanner, printer. If you wish not to do this, follow these steps:

    Check your hard drive for errors:

    Click Start

    Type: CMD, according to the results, right-click CMD

    Click on "Run as Administrator"

    At the command prompt, type: chkdsk /f /r

    When you restart your system, your computer will be scanned for errors and will try to correct them.

    then


    Click Start
    Type: CMD, according to the results, right-click CMD
    Click on "Run as Administrator"
    At the command prompt, type: sfc/scannow
    This will check for any breach of integrity

    Restart your system

    Also to perform a clean boot and see if things improve:

    Hello

    Usually, the system must be activated automatically when you first connect to the internet.
    If this isn't the case, I suppose there must be some serious problems in the system.
    The simplest solution would be the recovery of the laptop.
    Normal using the laptop back to factory State should solve all the problems of system and I wonder why the system recovery has not helped in the past...

    However, I recommend you to perform the Toshiba recovery procedure once more.
    After this, turn off the closure of the hybrid and a complete Windows 8, as stop described here:

  • Activation of Windows XP in the new computer.

    -Old hard drive, the new Machine

    I have a hard drive with Windows XP.  The machine from Dell, in which it was loaded crashes - most likely a motherboard problem.  I installed the HDD on another machine that has had its hard drive failure - virus suspected, etc..  The combination of 'new' hard drive with Windows XP and the Dell with the card mother work seems to work.  I get the error that I have to reactivate Windows XP to connect.  I can't connect Internet (I have not discovered why in this case) and the result by telephone (voice) says that ID is not on file (?) and gives a Web site for activation.  I can't access the Web on the machine, and the Microsoft Web site with the "solution" has the answer in form of download - once again, not good because I can't access the Web with the machine in need of activation.  The phone translates a computer, not a person.  I changed nothing other than to remove the hard drive of a machine which does not to whoever's doing.  What can I do?  Thank you.

    The operating system of Windows XP which is not the operating system on which was installed when you purchased the Dell hard disk from Dell? If so, it's probably an OEM version and as such is "related" to the system BIOS, it came with. It will not activate connected to a system with a different motherboard and a different BIOS. In addition, if an OEM, software license version is no longer valid because it is no longer used with the material with which it was purchased.

    The reason why you can't get an Internet connection is bound. Since the XP system on the hard drive has been used in the Dell system, it is configured to be used in the Dell. There the drivers for the Dell hardware installed. You will need to identify the current computer's ethernet card, download and install the appropriate drivers for this card.

    There are several methods to reinstall Vista.

    This can help you (download files and make your own DVDs):

    ___________________________________

    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:

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

    Them or us ask the right sequence of key.

    ___________________________________

    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

    And phone Activation may be necessary when you use the above installation method.
