  • Why my product key is invalid?

    I recently bought 4 computers I'll put in place on a network. They were bought with XP Professional SP2 already running.

    I got hurt so I ran a program to reset the SIDS network. It asked me to close my software, rebooted and then took me to the activation screen. After, I entered the product key that is located on a sticker on the back of the machine and now windows tells me the product key is invalid. Microsoft technical support gave me a new product key to try, but it came with the same problem.

    Computers are Olivetti Explor@300XS touchscreen terminals.

    I'd appreciate any help that would allow me to use them.

    3. Select your country.
    4. Select the telephone activation option and brace yourself for a real person.

  • Product key message invalid there a sense?

    A failure of the motherboard, I bought a refurbished with Windows XP installed system. It came with a CD of Windows XP for PC reconditioned.  My plan was to replace the old disk system (XP) with the reader in the renovated system.  I started the system with its original drive because I wanted to know just what device driver updated, I would need.  I finished installing XP but has not activated the operating system.

    After stopping and switching of the readers, when I tried to start with my old drive in the system, I get the message about activation. The activation attempt failed.  With a little research I learned that the OEM of XP version on my old drive was not transferable to another system. Always eager to keep my settings, software and data, I tried to use the XP CD provided with the renewed system to "fix" / "upgrade"the operating system on the old drive.» I thought that I will be prompted for the product key and it could use that matched with the refurbished COA label, as the CD package has loaded. I was invited for the key, but when I used the renewed COA key I received a message "invalid product key".

    This make sense or is something else wrong?

    Oh - sorry, I was under the impression that you got the operating system

    You can get in Mode safe mode with command prompt?

    If so, try this...

    At the command prompt, type this command exactly (space, caps and comma are required):

    Rundll32.exe syssetup, SetupOobeBnk

    Turn it back on.

    If you did it, your activation grace period will have been reset, giving you more time to work on the problem.

  • Windows Vista says that my product key is invalid for activation.

    I bought a dell Inspiron on 2007. He died this year and I bought a used machine, using the memory of the dead dell printer. I installed Vista on my disk and now recieveda message on my screen saying my code is invalid for activation! It's probably my drive. What they are up to?

    original title: not valid?

    Dell you provided with what we call an OEM of Windows version. OEM versions are related to the computer first it is installed on and can not be moved / installed on another computer.

    You need to buy a 'Full' version retail of windows (if the computer that you want to use never had an earlier version of Windows AND valid a certificate of authenticity).

    You can use an 'Upgrade' of Windows Vista (or Windows 7) retail version if Windows XP or Vista has been installed and you have always a product key and the COA.

  • Why my product key is invalid after I had my computer for 3 years?

    OK, I have had my computer for 3 years. I bought my new TI, but they said that I had the opportunity to make windows XP (as they said it was windows vista). If at that time, I changed it to windows XP (it was a real disc / legal). In any case, the problem now... I accidentally hit my computer and I stop three times dramatically by pressing right on the power supply. I think that this caused a huge problem, because when I turned it back on, I got a screen that asked my product key. It was already written in the box (it was the correct product key) However, it sucked! I then called on the phone and they said that my ID code was not valid/there was a problem. And now my computer says I need to activate windows, but I can't! Y at - it another option for me?

    * I also installed a new graphics card in my computer, but it was about 3 weeks ago and I have not had any problems with him.

    The key used here is NOT a given by MS - it's an OEM_SLP key, which can be activated by the presence of the markers suitable BIOS SLIC table.

    You must enter the correct key that comes with the XP disk - using the product key update tool.

  • New hard drive gets the INVALID disc Windows 7 64 bit upgrade product key!

    I installed Windows 7 Home Premium and within 24 hours, my hard drive is dead. I replaced the hard drive and reinstalling Windows 7 Home Premium with 64-bit disc. Everything went well until the time of the entry of the product key. When I typed in the key of this program returned an INVALID KEY message and instructed me to check and retype the key, I did. Product key message invalid was repeated. I have not installed a previous version of windows before you reinstall 7, and the installation program never asked me to check my right to use the upgraded version (Yes, I used the CUSTOM install method).

    The INVALID PRODUCT KEY message due to the absence of an earlier version of windows is detected on the new hard drive? I need to install my OLD version of windows before proceeding with Windows 7, can I? Please help me understand what is happening with this PC. I convinced my sister to be upgraded because Windows 7 is SO much in my PC, so that she bought the upgrade disc and tried for a week to get its system works as well as mine has inlaw for several months. I have not heard of someone having this much trouble with the upgrade to Windows 7.

    Product keys don't care equipment. They only care about the version of Windows that you are trying to install. (However, you cannot validate a facility later but this is another topic).

    If your product key is rejected, then you are two typing errors or you are using a key that does not match the DVD that you are using. This could happen if you use a MS Office key for a Windows installation to a key of Windows 7 OEM for a DVD retail of Windows 7.

  • "Blocked product key" message after factory reset system

    Since I updated to Windows 8.1, I had random BSOD errors. They were different from the errors and what they had in common was the NT kernel, which meant that I had to do a complete restore of the system. I have put this for awhile because it happened only once at startup, then the system is stable. Today I finally had the time to do and I was prepared for some annoying problems but not like that.

    At first, I did a system reset which now seems very useless for me because it only retains the Windows settings and more like reinstalling Windows to do a full format. Unfortunately it gave me this error message. I searched online and some suggestions made to make a complete and all factory restore, knowing that it would solve nothing I moved and you did. Suffice to say it didn't work as I knew that he would not but I thought I'd better get all "did you do X procedure?" before asking for help to avoid delays in starting this sorted correctly.

    Now I'm sitting here typing this out with the error message always insisting on the fact that my product key is invalid / blocked and as it took me a while to back up my files I will have to wait until tomorrow to contact HP support. Someone at - he found a complete solution to this or discovered why their key is blocked after a reinstall? If it is a new anti-piracy measure that went wrong so I'll be even more upset than I already am.

    To add to the trouble I have specifically excluded to install Norton yet found sitting here on my laptop at the first start. I also had a problem with WiFi really stupid where he would not stay connected for more than a half second up until I connected via LAN and updated the driver. Excellent software! What happens if I had no network cable? Why did the pilot WiFi broken out of the box?

    A few additional bits of information. The laptop is under warranty. I only got it in August and it has no DVD drive, so I had to rely on HP Recovery Manager to use the recovery partition.

    Apology. I forgot this post! Yes, I solved the problem, but it was not easy nor quick. The tl; Dr version is that HP has allowed me to buy a new key of Windows and then they sent me a check to cover the cost. If you are interested in a longer version, then read on. I would also add that my laptop was still under warranty at the time where it all happened.

    For some reason the laptop BIOS (where is stored the factory key) any had lost Setup sort key. I guess that happened during a many updates of BIOS HP sent but that makes no difference. What happened then is that I had to send screenshots of the error message Windows gave me to HP showing what Windows told me (that the key was not valid etc) and wait for HP to decide on a course of action.

    Many of these e-mails took days to get a response which was pretty frustrating given that Windows would remember every 3 hours that I didn't have a valid key. The end result is that count give enough evidence HP leave of me to go out and buy a new Windows key, and then send by e-mail a copy of the invoice for a refund. Given the slow HP had to get to this point, that is so not surprising it took them more than a month to send me money to cover what I paid. This figure includes two weeks after I did what they asked and nothing happened, but after the ring, I was told that he had not crossed for "any reason" that lead to another delay of two weeks before I finally got the payment.

    I realize that the question itself was not a typical scenario and I am happy with the end result but the time it took to get there (problem started a few days before the new year of 2014 and was resolved around March 2014) was ridiculous and seriously made me hesitant to go close to HP in the future.

    The installed operating system seems to be XP Home edition - which explains why your XP Pro key edition will not work.

    You need to reinstall with the appropriate Pro OEM media, using the key for Pro.

  • Faded to the Windows 7 product key sticker

    I had to install a new hard drive on my laptop and did not have a Windows 7 installation disc Toshiba - laptop came with pre-installed software. The sticker of the product key on the base of the laptop is faded, so I used 3rd party software and extract the key from the registry. I downloaded an iso of Win 7 and used this product key and all very busy, and I used it successfully for the past few weeks. Now, it is said, I have 10 days to activate my product key is invalid for activation. I have read various threads that keep that product key recovered and used for the loading of Windows & is not suitable for activation, so I'm back to faded sticker. I figured out all but one the letters/numbers and wonder if I enter the product key sticker, and I guess that last number (I think it's a B, a 3 or an 8), if it turns out to cheat should I get another chance to enter the product key and try one of the other numbers/letters combinations? Thank you

    You will never be able to activate a downloaded the ISO of Windows 7 with the key that came with the laptop. Your laptop came with a Toshiba OEM of Windows 7 version, and the ISO would be a commercial version.

    You have to get a set of recovery discs from Toshiba or purchase the complete retail Windows 7 installation.

  • What happens if I install a new windows on a computer product key OEM windows laptop?

    I bought a laptop in 2009 with Windows Vista Home Basic OEM on it (I still have the sticker of the portable product key).

    This year, I bought a larger capacity HARD drive and installed on my laptop.

    I thought it was the perfect time to upgrade to Windows 7, so I bought a DVD of Windows 7 Ultimate.

    I installed Windows 7 Ultimate on my HDD new and used the new Windows 7 Ultimate DVD product key.

    My questions are,

    What will happen to the product key Windows Vista Home Basic OEM?

    If it is replaced with the new product key?

    Is the OEM product key became invalid?

    Now I use Windows Pro 10, as a free upgrade to Windows 7 Ultimate, so...

    What my new Windows 10 Pro registered product key?

    I know that since windows 8, the product key is installed on the BIOS (am I right?).

    then, how it actually works?

    Thank you very much for the reply.

    Kind regards

    Hello

    No matter if you did a clean Windows 7 or updated installation to upgrade to windows 7 from Vista, this OEM Vista product key is blocked on this computer and cannot be transferred to another machine.

    You can only use this key OEM of Vista to reinstall Vista on this particular machine and start over.

    Licensing rules (my words)

    If the computer/laptop comes with the preinstalled Windows operating system (Dell, HP, Acer, etc.) or is licensed to OEM System Builders, that the product key that came with the computer/laptop is preinstalled OEM license and is not transferable.

    OEM license/product key (systems of operating pre-installed on Dell, HP, etc.) and the license OEM System Builders are related to the first machine it is installed on and dies when machine who dies.

    Only retail Operating System license that you buy and install yourself, are allowed to be transferred to another machine.

    And retail licenses also can be installed on a machine at one time.

    @@@@@@@@@@@@@@@@@@@@@@@

    Rec would be the free upgrade to 10 7 as Vista never qualified for the free upgrade to 10.

    The key/license Windows product to describe the operating system, Windows 7, Windows 8.1, etc. is absorbed by upgrading Windows 10 during the installation process and becomes an integral part of the active Windows 10 final installation.

    The license qualifying operating system, either Windows 7 or Windows 8.1, etc. cannot be used anywhere else, or in a dual boot with Windows 10.

    But there is no product key for your free upgrade to 10.

    Hardware configuration you laptop is stored on Microsoft servers and how your machine will be recognized if you always want to reinstall 10.

    See you soon.
