Windows 7 - Win 7 Prof not genuine and cannot enter genuine OEM product key

I recently downloaded SP1 to my Windows 7 machine and shortly thereafter a message appeared on the lower right hand corner indicating that "Windows 7 Build 7601 This copy of windows is not genuine". I bought this machine used and so I verified the key with Microsoft and it is a genuine OEM key but try as I may there is nowhere to enter a product key. I go to start-computer-right click- and at the bottom under Windows Activation it states Status: Not Available - Product ID: Not Available and NO place to enter a product key. Also all of the DOS commands that I can find on the Net do not seem to work either. When I contact Microsoft support they are no help at all and tell me I need to do a CLEAN install with the disk that came with my machine. The only problem is that no disk came with this machine. I have also been told by "Tech support" since I have an OEM key I just cannot use ANY install win 7 disk. I have a TON of Apps. loaded on this machine and it TICKS me off that I have a VALID OEM key and seemingly no way to enter or fix which I suspect is a Microsoft bug to begin with as they have overshot to prevent piracy. Someone Please help!

To properly analyse and solve problems with Activation and Validation, we need to see a full copy of the report produced by the MGADiag tool (download and save to desktop - http://go.microsoft.com/fwlink/?linkid=52012 )
Once saved, run the tool.
Click on the Continue button, which will produce the report.
To copy the report to your response, click on the Copy button in the tool (ignore any error messages at this point), and then paste (using either r-click/Paste, or Ctrl+V ) into your response.
- **in your own thread**, please
Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine, but do NOT quote the Key on the sticker!
How to Tell - Home

The key may be genuine, but it may not belong to this system. Use this Key Finder or any other key finder and compare the key in your system with the COA sticker on the bottom of your laptop.

The MGADiag report will tell us enough of the Key to know that - and knowing the other information on the COA sticker will also assist.

Yeah, and ??

...so we wait for the MGADiag report - and suspend judgement.

Also - it's quite normal for a Keyfinder to find a different Key to the one installed on a machine from a Direct OEM - and the OP has not told us the make/model of the affected machine.

NoelDP, WHS and Admins of this site-

I am sorry for the delayed response to this thread which I started some time ago. After I posted my problem above I left for Thanksgiving to spend time with my family and I forgot this machine at my home. So my apologies for the delayed response and my hope is you can still and are willing to help me.

I ran the winkeyfinder and have produced the MGAdiag report below. I can tell you that the winkeyfinder did produce a different product key than what is indicated on my COA sticker on the bottom of my machine. I do not know if this will be of any help in getting this resolved but winkey finder also gave me a product id which had a -OEM- within it's key sequence.

Please find my report below and again I apologize for not replying in a more timely manner.

Where did you buy this PC. The seller apparently manipulated the system.

NoelDP-

)ne more thing I forgot to mention in my last reply which I believe you need is the make/model of my machine. It is a Dell Precision M6300.

whs-

I bought it on ebay. I have made the seller aware that I am having this problem and they have offered to send me an extrinsic key to insert to make this genuine. I told them to send just before thanksgiving and have not heard from them since. Is this possible to make this genuine? The only way I am able to enter a product key is by typing -slui 3 from search and then during validation windows errors out with a 0XF807 error.
