Windows 10: Windows 10 upgrade from Windows 7 and digital license linked to MS account

I just completed the upgrade to Windows 10 but did not need to input a license key#. Apparently, my Windows 10 is activated with a digital license linked to my MS account. Does anyone know whether there is an expiry date for such license? For example, my MS account was created when I subscribed to Office 365 for a year. If I do not renew it after a year, will the digital license that is linked to my MS account also expire?

If you upgrade your 7 install to 10, which is worth it IMHO, make sure you link to a Microsoft Account. Otherwise you might not be able to easily regain the key if they block using 7 keys in the future.

You don't need to use the Microsoft account as your profile on so you can still bypass logging in at setup and creating a local account. All you gotta do to link your 10 account to your MS install (if you choose not to use your MS account as your profile), is to simply do the following:

• Click Start
• Click Settings
• Click Update and Security
• Click Activation
• As or with Admin permissions, click Add Account
• Login with MS Account credentials.

Then you should see a message that reads:

Link Microsoft Account to Windows 10 Digital License  


I cant see the option to link digital licence with microsoft account. I actually upgraded from a retail version of Windows 7 ultimate to Windows 8.1 by paying then to windows 10 pro.

Attaching the screenshot, there is no option to link to digital license to Microsoft account
