Windows 10: If I buy a new product key for windows 7 enterprise can I still activate my version of windows

A work computer is using win7 enterprise sp1 but the hard drive died and got replaced now it is asking for activation every 30 secs. There are a few place online still selling product keys for it. If I get one can I activate it? It may be a prior upgrade from xp. No we can't upgrade the os. To upgrade the os we would need to replace around $16,500,000 worth of machinery. Will a new product key for win 7 enterprise work?

Window 10 installation and activation using Windows 7 Product key

Hello Sourabh,

Thank you for contacting Microsoft Community.

Starting with the November update, Windows 10 (Version 1511) can be activated using some Windows 7,
Windows 8, and Windows 8.1 product keys. During the free upgrade or installation, you can use a valid Windows 7,
Windows 8, or Windows 8.1 product key to activate
Windows 10 (Version 1511 or higher). The following types of product keys are supported:

• 
  Product keys included in the packaging or the Certificate of Authenticity (COA) attached to your PC that came installed with Windows.
  
• 
  Product keys included in the confirmation email you received after buying Windows from an online retailer.
  
• 
  Product keys included in the box the Windows DVD came in.
  
• 
  Product keys you bought using Windows Anytime Upgrade or Get Genuine Windows.
  
• 
  If you bought a Windows 8.1 Pro Pack product key, you can use it to activate
  Windows 10 Pro.
  

After Windows 10 is activated, a digital entitlement will be given to your device based on the product key you entered. This means that you’ll no longer need to enter a product key to activate
Windows 10 on this device.

On some devices that came pre-installed with Windows 8 or Windows 8.1, the product key is provisioned in the device firmware. On these devices the product key will be verified during setup, and then the appropriate edition of
Windows 10 will be installed.

Note:

• 
  Some Windows 7, Windows 8, and Windows 8.1product keys can't be used to activate
  Windows 10, such as product keys for volume licensing, including Generic Volume Licensing Keys (GVLK) and Multiple Activation Keys (MAK), and Windows 7 Enterprise,
  Windows 8 Enterprise, and Windows 8.1 Enterprise.

Will a Windows 7 Ultimate key activate Windows 7 Pro?

No - Typically as far as I know, a Windows 7 Ultimate key will unlock Windows 7 Ultimate.

The thing is basically what is on the INSTALLATION disc is usually exactly the same no matter what version you buy, ALL the potential content is already on the disc, and it is the Product Key itself that tells the installer what options to install/how to install them, so that you land up with your specific product.

Take an Ultimate DVD, install , but enter a windows Home key, and you will most likely get a Home install.

... or am I 'trippin? Pro's weigh in?

 

Will a Windows 7 Ultimate key activate Windows 7 Pro?

I've tried the opposite, was installing Win7 on a friends comp, my copy of win 7 (home premium) and his key (pro). When I entered the key, it gave me an error regarding versions. Skipping the initial key input also lead to a version error thing when Windows booted up. One big thing I noticed when I did that was it didn't let you choose the version to install if you skipped the key input. In short Vista lets you use whatever disc to install, 7 doesn't.
