transfer serial

I built my pc system and purchased a windows 7 disc (or serial plus .iso).
Great system works perfect for 18 months. Motherboard is now knackered.
So I simply replace the motherboard, do a fresh install of windows 7 and am good to go again.
The disc I purchased back in 2009 has been used on 5 systems all through motherboard replacements.

Now let’s do that again with a purchase of a windows 10 disc (or serial plus .iso).
That serial number is now bonded to that motherboard, after the first install.
So some 18 months later and motherboard is now knackered.
So I replace the motherboard and again good to go.


Will I be able to use my windows 10 disc or serial that I purchased again or will I have to buy
another windows 10 disc or new serial??????????????????????????????

I would be more curious as to why you have to change MB's so often .

The disc is a Vista update to win 7 disc, 64 bit version pre sevice pack 1.
1 motherboard I damaged changing the cpu, another the bios chip broke, 4th (heat damage), 2 motherboards were given away to friends. 1 has XP, 1 has win 7.
nothing drastic.
As for my, product id no letters, whare as all my childrens win 7 systems do contain OEM.
my windows 10 product id, also is all numbers.
And yes both my win 7 main, and my free upgrade to win 10 system register as genuine.

That's a maze to navigate.

You have quite the collection of licenses. The OEM ones die with the motherboard. With one exception. If you have a Dell, then replace it with a Dell motherboard, Microsoft and Dell won't push the license into the grave.

Windows 10 licenses haven't really been wrung out yet. So for now if the OEM is the free upgrade based on OEM, the same rules.

As to RETAIL licenses there's latitude about board changes.

I hear you.

But the license varies with what version. Microsoft has been avoiding any head on lawsuit about this so the story so far is they hand out a key or do what it takes when your license is retail. OEM versions from Dell and such they haven't given much leeway on unless it's a Dell board in a Dell replacement.

In short, you might have to call it in.

I did notice the is a different in the KEY.

If the key doesn't have OEM on it, I am going to assumed the w10 is its w7 upgrade. Of course I have not change any mobo yet so I don't know what MS is going to do. But my thinking says this is a w10 retail. I agreed with Itsdigger, that's lots of board changing.

If you happen to use a Microsoft account on your Windows 10 PC, and link it it your PC, the activation troubleshooter will even accomodate a changed motherboard. tells more and tells all.

I read nothing in the Microsoft page that says this shouldn't work after the free upgrade. But you can't type in the serial number.

you did not say
Nov 1, 2016 1:52PM PDT

you did not say if the win7 disk was the full retail version or oem/system builders version. you did not say if you are replacing with the very same motherboard model or upgraded to a different motherboard every time it goes bad. It makes a difference as to whether or not the os can be legally use to justify an upgrade to win10.
