Windows 10: Windows 10 - Swap Keys on two Laptops Both registred to MS account

I have two Laptops. Both run Win10, one the Home version and the other the Pro version. Both keys and devices are registered to my Microsoft account. How do I go about switching keys between both computers, so that the home becomes pro and vice versa?

Win10 Pro - Digital Activiation - Not Linked to MS Account  

I've been doing some more swapping of OS on one of my machines recently, and checking my MS Account to see how it's list of devices behaves.

The key step you may have missed out is to sign in to your MS account once you have the OS up and running. You don't have to sign in to the PC with your MS account, just signing into an app like the Store is sufficient.

Seems that a 'device' is defined by the hardware ID or serial number of the PC, not the name your Windows uses for it. On recognising that it's the same machine but with a different name the existing entry in 'My devices' gets updated rather than appearing twice as separate devices.

 

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.

 

Loophole Lets You Freely Upgrade to Windows 10 After Offer Expiry

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:
