Windows 10: Windows10 Pro keys and Win10 OS costs?

I'm looking for a fresh Win10 OS for a new PC built.

I've seen keys for $30-$40 and packages for as high as $200

What's the difference here? I'm confused.

Windows7 Pro 64bit Drivers are not working in Windows10 Pro 64bit

I have upgraded to Win7 to Win10 Pro 64bit,have not ever used Windows8.

So the drivers used in Win7 are not inalling in Win10.

In compatibility mode there are only 2 OS ,Win7 and Win8.

But windows10 is not listed.

What to do,if you say in details,plzz..........

 

Built new computer, running unactivated Win10 Home, have Win7 Pro key

I was initially thinking of buying a Win10 Home key, but I realized I still have a Win7 Pro key I purchased that I have never upgraded to Win10 and is not currently in use.

Two questions

• Can I use the Win7 key to activate Win10 (or is that no longer an option)
• Will Win10 Home turn into Win10 Pro (assuming I can still use key)

 

Can't upgrade from Windows 10 Home to Pro

Hi Bill,

Thank you for posting your query in Microsoft Community. We apologize for the inconvenience caused and will assist you in the best possible ways.

I suggest you to download and create an installation media for Windows 10 Pro form the link provided below:

Download Windows 10

After the installation media is created, suggest you to upgrade to Windows 10 Pro from the installation media. When the upgrade asks for product key, enter the product key purchased for Windows 10 Pro. If it does not accept, suggest you to skip the activation
step. After the Operating System is installed, suggest you to activate by phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select the Region from the list and click Next.
• Call the Toll-Free number provided on top and can activate via phone.

Hope this helps. Keep us posted on the status for further assistance.
