No, I am not asking for someone's product key.

I have a computer that originally had Windows Vista, but it was updated to Windows 7 quite a while ago. I want to try and sell this computer, but want to restore/reset it so that all my information has been removed. If I restore it, will it reinstall Windows Vista or Windows 7? If Windows Vista is reinstalled and I use my Windows 7 disc to upgrade it, can I use the product key found in the computer's properties information window prior to restoring it?

If that's a factory-brand computer and not a self-built computer, please advise us what its brand name and model name and model number and serial/service tag number is.

Was an "upgrade" install done from Windows Vista to Windows 7, or was a "clean" install done of Windows 7?

How was Windows 7 activated after it was installed?

I do not know if it was a clean install or an upgrade. It is a Dell Optiplex 780. Service tag is 70F33M1.

According to that service tag number, you have THIS Dell OptiPlex 780 Mini Tower.
According to its support site, it was purchased new on February 17, 2010 in the U.S. and came with Windows Vista Business SP1 32-bit.
The Certificate-Of-Authenticity sticker on it which has the Windows version and 25-character product key should confirm that.

You say you don't remember if a "upgrade" install or a "clean" install of Windows 7 was done.
Which Windows 7 version (Home Premium, Professional, Ultimate, Enterprise) and which bit number (32-bit, 64-bit) was installed?

If done with factory restore disks from Dell or ones you made when the computer was new, it will restore to Vista. Exactly how it left the factory with no updates and lots of extras that might not be wanted.

I use my Windows 7 disc
Is this a MS disk?

Premium 32 bit. I bought the computer used from someone who had already put Windows 7 on it.

If that Dell OptiPlex 780 minitower originally came with Windows Vista Business 32-bit, and then Windows 7 Home Premium 32-bit was later installed in it, I seriously doubt it has a functioning factory restore/system recovery feature.

I've owned several Dell OptiPlex 780 minitowers, so I know what hardware comes in them and which Windows operating systems it can run.
If your intent is to sell it, it's going to involve many hours of work to re-do it, and you will get less than $50 for it.

So when I go to into "system properties" and at the bottom of the window it says;

Windows Activation.........
Windows is activated
Product ID: #####‐OEM-#######-#####

Would that be the product key I need if I wanted re-install Windows 7?

If you use the restore discs created when the PC was new & running Vista then it’ll clean install that OS, if you use your Windows 7 disc then it’ll clean install Windows 7.
The OEM key is most probably Vista, you’d need the Win 7 key from the packaging.

It is the identifier for your particular PC for the license I believe.
Everyone who upgrades to Windows 10 from a previous version uses the same product key so this is what the ID is for.

The product ID and key are two different things but it is confusing. The product ID just identifies what version of Windows is running and you can post it in the public forum. If it starts with 00359 then it's Windows 7 Home and if it starts with 00371 it's Windows 7 Pro.

The Product Key is the license key that you need for activation.

The following will tell us more and could reveal if the installation is not genuine. Please run the MGA Diagnostic Tool and post back the report it creates:
  • Download MGADiag to your desktop.
  • Double-click on MGADiag.exe to launch the program
  • Click "Continue"
  • Ensure that the "Windows" tab is selected (it should be by default).
  • Click the "Copy" button to copy the MGA Diagnostic Report to the Windows clipboard.
  • Paste the MGA Diagnostic Report back here in your next reply.

Thank you for a direct answer.

I see you've marked this solved but I would still ask that you post the report I requested.
