Windows 10: Win7 Ultimate and Win 8 Pro Disks?

I have 2 Retail disks and one PC. Normally run Win7 and Win8 Pro on separate SSD's
Win7 is ran like 99.9% of the time .*Think

From what I read, you can use these CD's on other systems if my motherboard goes bad or I build another system

If I upgrade to Win10 from Win8 Pro and later on from Win7, will both product keys be active ?

Thanks

Win7 sp1 Ultimate and Win8.1 Pro Question ?

I have 2 copies Win7 and 8 and both can upgrade to Win10.

I only have one PC

I have Win 7 and 8 on separate SSD drives and the Win7 is my main one

If I run the update on my Win8.1 pro first to see how it works,

will I be able to run the Win7 update later on using a SSD that contains Win7 Sp1 Ultimate

Got both copes from Microsoft, not OEM

Thanks

WIN10 HOME OEM UPGRADE TO WIN 10 PRO

dears, I have bought a new PC coming with an OEM WIN 10 home to replace a crashed PC running on WIN 7 ULTIMATE. can I upgrade the new WIN10 HOME to WIN10 PRO using the WIN7 ULTIMATE license key? thanks.

 

RE : From what I read, you can use these CD's on other systems if my motherboard goes bad or I build another system

You must uninstall the Win 7 or Win 8 from the computer FIRST, before you can use the disk(s) for another computer.
The rule is : 1 key, 1 install.

RE : If I upgrade to Win10 from Win8 Pro and later on from Win7, will both product keys be active ?

Your Win 7 and Win 8 product keys are tied to the Windows 10 installed. You can NOT use the keys for another computers.

 

I found this several places. This is from Microsoft

What happens if I change my motherboard?
As it pertains to the OEM licenses this will invalidate the Windows 10 upgrade license because it will no longer have a previous base qualifying license which is required for the free upgrade. You will then have to purchase a full retail Windows 10 license. If the base qualifying license (Windows 7 or Windows 8.1) was a full retail version, then yes, you can transfer it.

 

A motherboard is essentially the computer.
New motherboard = new computer.
While a retail license is transferrable, it has to be uninstalled from one computer first before it can be used to another computer.
Failing that, you will have to buy a new valid product key to install to the new mobo.
That's my understanding.

Why don't you wait a bit for others to fill in the answer.

 

I had read "stories" about user having a dead mobo, went ahead and bought a new mobo and managed to "sweet-talk" MS into issuing a new product key.
If true, it could only be exception to the case.
I wouldn't count on it.

 

Absolutely false information. Nothing happens to the Windows 7 or 8/8.1 product keys after an upgrade to Windows 10. The same rule applies as if you never upgraded - uninstall the Windows 10 on the old computer and use the Windows 7 or 8/8.1 product key on the new computer. 1 product key - 1 Windows install - and it does not matter if the Windows install is the original Windows 7 or the Windows 10 that resulted from the upgrade.

Right from Microsoft:

Please read my reply again.

The OP's questions is :
If I upgrade to Win10 from Win8 Pro and later on from Win7, will both product keys be active ?

I said the keys are tied to Windows 10 installed and the keys cannot be used on another computer.

The OP did not ask................ what if I uninstall Windows 10.
The OP did not ask................ can I use the Win 7 or Win 8 Pro key to reinstall Win 7 or Win 8 Pro.
