Windows 10: Activated Windows 10 Product Key lost in deleted partitions

So yesterday my PC was installed with a legit activated version of Windows 10 Pro and unfortunately I ran into some major problems and had to completely reinstall Windows.



At this point I'm most concerned about my Windows license. Now my PC is running Windows 10 pro with a whole new product ID and product key, I had to overwrite the partitions to reinstall Windows and now I don't know if I can get that license back.


I'm really not trying to spend $100+ on another Windows 10 license.


I tried looking at my Microsoft account but it only shows my this PC so I can't transfer the product key or anything.


Does Microsoft have a contact email?

Activate windows 10 after re-installing (I have lost my product key)

I own a Lenovo T430 laptop. In 2017, I installed Windows 10 using my original Windows 7 product key. Unfortunately, I cannot find that product key anymore. I need to re-install windows 10. Will it be automatically activated after the installation, if I skip the step of asking the product key during the installation?

In my opinion, I believe that my laptop will have a digital entitlement stored on the Microsoft Activation Servers and this will not be a problem. Is that true?

If not, please suggest me a solution or a workaround.

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

windows 10 key

Google and download the "Windows 10 media creation tool"

Create a USB flash drive ISO and that's all you need...it will work without needing a key..
Just skip past entering a key during full install and delete all partitions, format, create new drive and install...

As long as you have upgraded from Windows 8 first...you need to do that prior to using your Windows 8 key for 10.
