Windows 10: Trouble reactivating licenses after reinstallation of Windows 10

Hi Everyone

I will try to keep this brief, but it is a little complex...

My company bought 300 Windows 10 licenses for products we were providing to our client. We were able to activate all the licenses in our assembly line (in China), although we had to use the Microsoft internet-based activation service.

When our product was shipped to our client, they decided to update their operating system (additional programs etc) and chose to create a master image. They "installed" this image on all 300 units, and when they tried to reactivate the Windows license, they got nothing more than an error message (from the activation service). Trying the telephone activation service also bore no fruit, so we ended up having to replace the licenses.

We sent the originals back to our supplier, who has said that there is nothing wrong with them. Also, of the 300, not all failed (although it was a very high failure rate).

As far as I was aware, as long as no hardware changes were made to the PC, the license should be able to be reactivated on the individual PC even if the operating system has been reinstalled.

Can anyone shed any light on why this is happening, and if there is any way to solve this problem?

I know the licenses are not "Volume Licenses", so the count should not be a problem either.

I am happy to answer questions, and would like to hear your feedback.

TIA

:)

 

Does Windows 7 require reactivation if...

He is using AMD already. He wants downgrading to AM3. Don't know why??

If you change HDD + RAM simultaneously, Windows 7 needs to be reactivated. Only HDD cloning shouldn't require reactivation. As you are changing mobo + HDD (prehaps RAM upgrade too), you will surely require reactivation. If you have genuine license, you should reinstall OS (you might use Windows Easy Transfer). If you don't want to reinstall, you need to uninstall HDD, interfaces/system devices, and numerous other drivers (USB, HID, Portable devices, etc.), else your OS will be unstable.
I will highly recommend to reinstall Windows 7 and enjoy your migration.

A simple trick might be like this to avoid reactivation:
1. Clone your HDD first and boot into Windows
2. Use it for at least one week
3. Replace mobo only without any other hardware change/upgrade and boot
4. Use it for at least one week
5. Do any other upgrade (RAM, Graphic card etc.)

Don't do two simultaneous downgrades/upgrades to avoid reactivation.

 

Reinstall Windows 10

Once Windows 10 Upgrade activated it assigned a permanent Digital License to the PC to reinstall as often as you want, change any hardware you like up to the motherboard - which requires some special steps spelled out in

Reactivating Windows 10 after a hardware change.

Follow the steps in
Clean Install Windows 10 to reinstall Windows 10 to your new SSD. It will reactivate shortly after connecting to the internet. If not open the Contact Support app in Start Menu and ask for help.
