New product key to replace invalid product key

Q: New product key to replace invalid product key

Just discovered that the Win 7 Professional Retail Version I purchased, downloaded & installed has a bogus product key. I've since ordered a genuine Win 7 copy. When it arrives, can I just enter the new product key into the existing system without reinstalling Win 7 again, following the "change product key" instructions? If not, is there a way to do this without a reinstall?

Preferred Solution: New product key to replace invalid product key

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I have a toshbiba Satellite L750-1XK and managed to get a Windows 7 Installation Install Disc as the owner of the laptop did not make a recovery disk. The owner reported that the laptop would not startup and when i looked at it the hard disk had stopped
I brought and fitted the new disk drive and booted up from the CD and installed windows 7 64bit software. All went well untill i entered the product code from the sticker on the bottom of the laptop and was informed that the product key was invalid. The
operating system has installed and is running ok BUT the network controller has not installed and as such I cant get the laptop on to the internet to get any further.
I did try to get a disk from toshiba but there web site says that windows 7 is not supported so i cant get one from there.
Why does the product key come up as invalid?

Hi there, can somebody please advise me on an XP re-install problem that I am having!

Basically, I have reformatted my laptop and reinstalled XP from the original cd supplied when I got the laptop... but when I get to the enter product key screen and enter it, it tells me that I have entered an invalid product key. The original product key is on a sticker on the underside of the laptop, so everything should be cool! It's a sony vaio that I got about 4 years ago with XP pre installed!

Anyone got any advice? Thanks in advance


A:invalid XP Product Key

Hello Declan,

I believe for both Windows XP Pro and Home edition's you can continue to install XP without the product key. Even if it prompts you just hit next and say yes to continue to install XP without the key.

Eventually you'll need to activate it, and calling Microsoft in your position would be the best thing to do. If you live in Canada or US you can call 1-888-571-2048, otherwise check the activation wizard to get the correct phone number.

Follow the instructions and if the product key doesn't go through you should get a phone representative that will help you activate your laptop with your product key.

I've had product keys not work with there original cd's as well!
However calling Microsoft to activate with that key has not failed me once.

Hope this helps.

I have MS Office 2003 which is still quite adequate for what I need it for. I am changing it to a new computer and once it is set up on the new computer it will be removed from the old computer. It is one of four licenses through the Volume License program. There are only four copies in use.

I am trying to install it on the new computer but it is coming up as an invalid product key. I am not sure why.

Part of my dilemma is also that I am installing it on Win XP via Parallels 7. The old installation was via Parallels 4. I had no problem installing it.

I wear out computers quite well so it has been transferred to new machines through out its history as one machine became obsolete. In this case, my older iMac needs to be overhauled and I can't do that until I can remove Office which I can't do until I can get it loaded on the newer machine which is much better suited to run the double operating systems. Until we switched to Mac, I also routinely did a new system install on my PCs as the computer would be sluggish. I am saying this to state that this software has been reinstalled on multi machines over the years BUT has only been active on one computer at a time. The other three licenses are in use by other individuals.

I am also using the original disk. I know we have had problems doing any kind of install from the back up disks.

Thanks for any insight you can give me as why my key might have now stopped working.

I upgraded from Win7Pro to WIN10 and had a partial install of the Win10PRO Op. Sys.  I tried to re-install Win10 PRO without luck and when I tried to go back to my provious operating system (Win 7 PRO) it asked me for a product key to preceed.  When I enterd the product key of fhte sticker on the side of my computer it says that is an invalid key that was used by the manufacturer (something like that) and I should contect them for a new key.   My computer is no longer supported so HP wants me to buy another key - I have an official key so cannot justify buying a new one.   Now I'm stuck with a partial install of Win10 that I cannot fix because it always crashes when I try to download the Win 10 files to reinstall it.  My system is messed up and I know I can fix it if my peoduct key worked.  Why would the key be supplied on the sticker if ti si no good?   

A:invalid product key

First verify that the Windows 7 product key on the sticker is actually for Windows 7 Pro.  Most OEM stickers indicate Windows 7 Home Premium.  You could always use the Recovery Manager from the D: Recovery Partition, if it still exists.

After systme upgrade for free to Windows 10, systme did not work ex: All in one printer fax would no longer scan. After many weeks of forums and boards fell back to system reset. So recoved computer from the system image. After recovery and startup, windows activation came up to tell me that the product key was invalid.  It asked again each time a recovery to the original out of the box state. It after upgrade to 8.1 is still asking for a valid product key.I contacted microsoft and discussed this issue, Microsoft did a remote access to my system and tryied to activate and after review of the product key saved in the system Bios instructed me to contact HP for assistance. Well here is the delima...no phone number to call...only forums and trouble shooting messages that do not address this issue. I will not pay for another key...if this is an issue world wide it is in my best intrest to replace it with MAC. This all started as a free activation to windows 10......Regards.

I've just built this new system having had my old MoBo fail on me. On that system I had Xp professional running off the one of the 2 x Western digal hard drives.

I am trying to install Win Home Prem 7 SP1 64 bit bought from Ebuyer.com in the UK.

Installation 1: I connected the Samsung SSD as the primary drive with the two western digitals attached (including one with XP still on it). I installed Win7 onto the SSD - which was quick and fine until I got to the activation stage - which said my product key was invaild. I tried several times. Didn't work. I called to activate and the support person said there was a upgrade problem. I didn't select upgrade during the installation process though.

Installation 2: I disconnected the 2 x western digitals and formated the drive using the Format feature in the Win7 set up. This installed a different Win 7 alongside the existing one (giving me a dual boot on the SSD - even though I formatted the drive?!). Product key still invalid.

Installation 3: I format the drive using the Command Prompt in the Win 7 Set up process. Then restart - and install again. 1 version of windows this time - but still product key invalid.

Insallation 4: I boot the PC using the western digital XP drive, and try to upgrade it from within XP - this doesn't work as XP is 32 and Win 7 is 64 !

Installation 5: I format the SSD using the device manager/disk tools in XP including the Clean function. Disconnect the Western digital drives. Install WIn... Read more

Alleight guys, here's the deal. I put a new HD in my computer earlier this afternoon. Tried to install Xp, but I keep getting an invalid product key error. This is the same key and disc I used before. I called micosoft and the guy generated a new key for me but it still gave me an invalid product I'd error. Anyone got any clue what's going on? Would clearing the CMOS on my mobo fix the issue? Thanks

A:Invalid product key?

In order to install Windows on your system, you must activate the product using a valid product key. After you enter a product key while installing Windows if system reports it invalid, the possibility is that you have entered a wrong product key. But if you are sure that the key entered is valid, there might be several reasons causing this behavior including hard drive damage. In case of hard drive damage, you need to replace it and restore lost data from backup. But if backup fails to restore, hard drive recovery solutions come as rescue.

While trying to install Windows XP on your computer, when you try to enter the product key, you encounter the similar error displaying on screen:

"The CD Key which you entered is invalid. Please try again."

You might also receive an error telling that the product key used is invalid.


The above error might be the outcome of below possible reasons:

1. Using an invalid product key

2. An antivirus program is scanning the computer

3. Windows XP installation CD is damaged

4. Hard disk is damaged

5. Incorrect system date in CMOS (Complementary Metal-Oxide Semiconductor) settings

6. Some extra drivers are installed that are interrupting the installation


You should follow these steps to solve the existing problem:

1. Make sure that the product key you are entering is correct. Try making use of keyboard number keys instead of numeric keypad

My Windows Xp Pro is fully activated but to my surprize when i tried installing SP1, I got an error message that my Windows XP product key is invalid and therefore I cannot install SP1.
I thought if your product key is invalid, Windows is not activated and you get reminder to activate within 15 days. But in my case Windows is fully activated, so how come my product key is invalid. What does this activation of Windows exactly mean. Could anybody please explain me that?


A:Re: invalid product key

There were many keys floating around that allowed you to activate XP but were not legal. Microsoft maintains a list of common keys used in this way and if yours matches, you cannot install the service pack. Assuming the key you used is one of these, you are running a pirated version of XP.
Do you recall where you got the key from? Did someone give it to you? Did you give it to anyone else?

Would appreciate some help, please.Bought a Toshiba Satellite T135-S1309 on eBay. It was advertised as being factory reset.Turned on the laptop, and get Windows 7 Home Premium 32-bit, but, it was not validated, the Toshiba Recovery partition was gone, and there are no Toshiba utilities, or any Toshiba software to be found.The COA sticker has a Product Key, but it is so worn out, you can only read 4 or 5 letters out of the 25.Contacted the seller and was given a Product Key 6B88K-XXXWY-4FXXX-MXXX3-W8DQG (Xs added by me, there are actual letters/digits provided) which immediately struck me as a hacking trick. Anyone with knowledge of this key can figure it out.The above Product Key did not match any of the few letters legible on the COA.Is the above key valid, or used by Toshiba?Thanks in advance for your reply.

A:Invalid Product Key?

That question...should be asked of whomever provided you with the key.
FWIW:  Microsoft maintains a list of known license keys which have become invalidated.  If you can find that key using Google...I'd say that it's less than legal .
Microsoft is responsibile for determining...whether a giver user has a valid license key...no one here can determine such.
As for Toshiba...a Toshiba representative may be able provide recovery disks for said system, if contacted.  They might even be able to verify the license applicable.

So I'm stuck at the "Your Product Key" window of the windows install and the "The CD key you entered is not valid." Can't pay for Dell support. We bought and own the machines.

You need to use the correct version I.E. SP1, 2 or 3, OEM or Retail disk and and key , for example a SP2 key will not work with a SP1 disk, is the disk you have a Dell OEM disk or a retail disk?

I have read that Win 8 stores the key on the motherboard, and that when installing Win 8 it will pull the key from the motherboard.
Is this true? and will it work?



A:Will I need a Product key if I have to replace HDD

Hello WAX,

If your laptop originally came with Windows 8/8.1 installed by the OEM, then it'll have its product key embedded in the UEFI firmware chip of the motherboard.

When you install Windows 8.1, it'll automatically detect the product key if it's the same edition the key is for.

Hi, thanks in advance for your help.

Trying to install an OEM version of Windows 7 Pro on a Dell Optiplex 620.

During install the product key was not recognized, got on the phone with Microsoft who said to bypass the product key install and do it later.

After installing I was unable to activate using the product key and Microsoft told me nothing useful other than "the OEM product key shows as being a valid number but it isn't working for your system so return it and get another one". Not possible to return it at this point I purchased it a while ago.

I'm getting the same message. Again I had windows installed for a few days before the Validation error thing started. It also makes my desktop background black. I got this copy of XP Pro from E-bay. Maybe a scam. But it's a valid copy. Copper hologram on disc. Disc envelope was sealed. Disc and Booklet were shrink wrapped. It was never attached to a PC though. The Product Key sticker is still on the booklet. My PC is a Dell. It came with Vista... I got sick of that. Bought a new Hard Drive and this copy of XP Pro and installed them. Any ideas?

A:invalid copy of -product key

Did you buy an OEM version or full retail?
You sure you've entered the 25 digit product key correctly?
You could try calling Microsoft to tell them that you bought a new copy of Windows and it won't validate.

Hi guys, I require some assistance. I have recently been forced to format my HP Pavilion dv6. To do this, I reinstalled Windows 7, but a trial version I had lying around, and entered the product key found on a sticker at the base of my laptop. The product key seemed to work just fine (as it should) but lately ive been given a pop up window upon start up stating that the product key I entered is invalid for activation, with 3 options: Automated phone system, Buy new key online, Type a different key.

I doubt I made a mistake upon typing the key as it was accepted upon the reinstallation of windows. I also have no idea if I will be limited to entering a key or shutting down in the near future. I still have the folder Windows.old, would that be the cause? I cant see why....

In this household there are 2 PCs and 2 OEM copies of Windows XP SP1.

Last week the power to my PC was accidentally cut while it was running, and it refused to boot. After unsuccessfully trying to fix it (several suggestions didn't work) I gave up and tonight decided to just reformat and reinstall windows as I have full back-ups of my data.

When I got to the Enter Product Key part of the installation, the key on the sticker on my PC's case was Invalid. I have never had a problem with Genuine Advantage or any other product verification while using that computer and it had been fully up-to-date at the time it broke.

My motherboard in my old PC failed 18 months ago and I had my surviving components put into a new case by a local PC shop. They (presumably) just stuck my existing sticker on the the new case, they also asked for my XP disc to install the OS. Since then this is the first time I have reformatted.

Suspecting I had accidentally switched the XP CDs, I tried entering the product key from the side of my mum's PC - this key worked. The keys on mum's PC (the one I am posting from) and my PC (which has not been used), now match...

So if the CD and the product key don't have to match, why on earth didn't the key on the side of my PC work? I really don't understand.

Is there a way I can change the product key on my PC for the "correct" one on the side of its case?


A:Invalid product key on legit XP - help!

I suspect that the cause of your problem is contained in your statement:
"My motherboard in my old PC failed 18 months ago and I had my surviving components put into a new case by a local PC shop. "
Some OEM verions of the OS only work when all the components are the OEM ones, and
That may be where your problem lies.
Or if the OEM CD's are actually different, then you may indeed have switched the CD's.
Generally speaking though it is the Number that matters, not the CD, and in non-OEM machines the disks can be freely interchanged. You can even make your own new install disk containing uptodate service packs, and use that for reinstall (a slipstreamed disk).
There is a legitimate way to change the code:


If you do run into a problem then you will find Microsoft can be surprisingly helpful on the phone with genuine cases of key problems! Call them if the process does not complete properly, and you will get the help you need.

I just reformated the hardrive on my home computer. When I go to install Windows XP Home Edition, when I type in the product key it tells me the product key is invalid. I know the product key is not invalid! It just won?t work, know matter what I do.

A:Invalid Product Key for Windows XP...but it's not!

if the key you are typing in comes from the packaging of the cd you are using, then it should be working fine.

is it possible you accidentally grabbed the jewel case for someone else's xp cd, and they have yours?

i am assuming this is an original, so you shouldn't be having trouble reading it, so we'll rule that one out...

if it's a copy, then you should know better than to ask on a microsoft partner site.

otherwise, if this is an original xp cd, and you have the correct packaging for it, then there literally is no reason the key wouldn't work, unless you typed it in wrong.

you will probably have to call microsoft, and talk to them about buying a new key.

i wish there was more i could say about it, but we don't have any way of helping you get a new key, and we don't have any way of helping you bypass the key.

on the other hand, if you are holding a 100% genuine xp cd, and it's in it's original case, and the key written on it doesn't work, you might be able to send it to microsoft for a replacement.

it makes me wonder greatly how in the world you installed it last time.

Ok heres my issue. I had to send my gateway MT6451 laptop to gateway to get a new motherboard replaced. When they sent it back to me i was getting errors stating that my Microsoft Vista Home Premium 34 OEM product key is invalid. I contacted Microsoft who then gave me another product key that STILL didn't work. I was told the reason its invalid is because the old product key is tied to my old motherboard. Well i contacted gateway and they had me do a clean install of vista. That STILL didn't work. Then they had me insert my operating disc and i got an error stating "windows cannot find the required files....corrupt..blah blah error code 0x80070017" So i contact gateway because this is STILL under warranty. Well they suggested to me that i send them 20 dollars for a restore cd. Now if its my understanding this issue should have been resolved and fixed when they replaced the motherboard, but it wasn't, so I'm not paying 20 dollars for something they have to fix. They told me this is my ONLY option. First if i had the 20 bucks i would probably do it but I'm a college student and i just don't have it. Second, my roommate stated he has 2 different versions of Windows XP, a 64-bit and a 34-bit.....can i install this in order to fix my computer? I know nothing about how to install different versions of windows and i have no idea which one i should use. Any help would be great! I'm done dealing with gateway and have also filed a complaint ...

I own and operate a Computer Repair shop. A customer brought in an HP 2000 Notebook after she had a scam attempted on her.  When she refused to provide personal financial information, the scammer, who was remoted in, put a Windows Startup password on it.  I reloaded the laptop using the recovery partition.  The Windows 8 OS reported that the product key was invavlid. It continued to do so even after I upgraded to Windows 8.1.  I am assuming that the scammer had something to do with this.  I know her key was good, as this is the second time reloading her machine due to scammers, (she is very old and vulnerable), and it worked the last time.  What I need, very simply, is her Product Key for this machine.  She can't find anything that shows it at home.  S/N: 5CG3021SKY. Any help you can be would be GREATLY appreciated as this is my last option, (HP doesn't appear to have a way to just call them, and the support chat only works if you are still under warranty).

I had a hard drive failure and reloaded Vista Ultimate signature back onto the new drive. I kept getting invalid product code (it was def. the one on the box). Yesterday Microsoft informed me I would only have limited functanity and it would cost ?109 to sort out as they longer supported Vista. I said all I needed was a new product code, but they refused. Et voila my PC today can only access the internet for half an hour at a go. ANy advice on this?

A:Invalid Product code - help !

with microsoft you can only use a product code once and that's it, unless it is a system restore disc that came with your computer you can use it to your hearts content.

The product key is embeded into UEFI firmware and you can view the key using the free program RWEverything:http://www.top-password.com/blog/2-options-to-find-windows-8-oem-product-key-easily/ The product key should never be erased even if you reset or refresh the OS.
