Reinstall Windows 7 pro using the existing key

I want to reinstall Windows 7 pro on my laptop. There is no change in the material, I have to purchase a new license or can I use my existing key?

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

If it came preloaded on your computer:

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.

This is how the recovery partition is accessible to 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 LG, 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.

For Samsung, press F4 to the power upward...

For Fujitsu, press the F8 key directly after the power

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

Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".

    If it worked the first time, there is no reason that it will not work the second time on the same computer, as long as the Windows 7 is a full version.

    If this is an upgrade version, you must have the qualifying OS installed and enabled before you upgrade and it will work.

  • Tecra R850 with Windows WXP - cannot use the FN key

    Hello

    On a Tecra R850, I can't use the FN key. I installed all the drivers for toshiba and they does'nt work

    Help

    Thank you

    Hello

    All this is a bit complicated with WXP and it is important to install everything in the right installation order. After some base such as chipset, display and sound drivers you need to install the common modules at the beginning and continue with Toshiba-specific tools and utilities like controls, screen, energy saving and so on.

    You can use a combination of FN keys or none of them does not work?

  • reinstalled Windows XP Pro on the new HARD disk, not invited to key code

    My Dimension 9200 needed a new HARD drive. Ordered from Dell, installed HD then re-installed Windows XP Pro sp2. I forgot to unplug the media reader, so I had to reinstall it again to get HARD drive letter assignment as C. Added drivers in good condition and just download and install sp3 and all the necessary updates. Now, all that remains is to transfer all the files from the old HD.

    Never, I was invited to the WinXP key code. I DO have the Dell OEM disc as well as the installation key code in the original Dell factory. I was wondering if anyone else had the same "problem". I checked under administrative tools and don't see anything that ask you "activation". The only thing that I went off and was invited to provide was the key code when I installed MS Office 2003. When I check in system properties, General, it shows that it is registered to me and some numbers with Dell OEM then more numbers, not the OS key code well.

    Anyone can shed some light on this? Thank you

    When you use a Dell OEM media on a Dell computer, it checks the BIOS to make sure that it is install on a Dell computer, then it will be activated automatically, using a generic OEM key.  As long as you have the sticker COST/License/Product Key, you have the right to run Windows on this computer.  That's pretty standard for OEM systems.

    System properties still shows a 'code', not the actual key.  You can use Magic Jelly Bean to retrieve the key used to activate Windows, but the key, that he will return does not match your COA and cannot be used for manual activation.

  • My Pc crashed and I need to reinstall windows, but it indicates the product key is already in use

I checked the places of response and they tell you a whole different way in this way and I tried but it won't work.  I also tried to restore my computer back before that I was thinking when I got the Virus, but that only goes so far I'm crazy to go.  Please help me I need my computer for work.

    Thank you very much

    Thank you

    auntsands50,
    Thanks for posting on the Microsoft answers Forum.  I need to get the details on your situation.  You say that you want to uninstall XP?  It will be the only way to install another operating system or use a program that will allow you to erase the hard drive.  You mention that you got a virus and you tried to do a restore.

    So my question is what are you trying finally to accomplish?  Do you want to just get a virus on your system or you want to wipe the drive and reinstall XP.

    If you want to remove a virus, then here is a link to a program free antivirus that you can use to help clean your system: http://www.microsoft.com/Security_essentials/

    If you want to restore your system to factory default then you will need to boot from your XP cd or use the OEM solutions provided with your PC.  http://support.Microsoft.com/kb/316941 Mike - Engineer Support Microsoft Answers

  • Re: Unable to activate Windows Vista Business using the Microsoft key

    I am facing difficulties to activate the microsoft package, whenever I enter the product key printed on the label attached to my pc, it says wrong key.
    Help, please.

    The key to Microsoft, that you can find on the lower side of your laptop is not a kind of universal key and this key belongs to Vista preinstalled on your laptop. You got your laptop with Vista preinstalled. With your laptop, you have paid a license and an operating system.

    After recall of Toshiba you must create Toshiba Recovery DVD or this facilities you can use if often you want with your laptop. This version of Vista belongs to you and can only be used with your laptop.

    If you are using Microsoft facilities DVD you must have the key for this version. If you do not, you must purchase a key online and activate a preinstalled Vista version.
