Windows 10: Windows 11 Key for Windows 11 Pro?

HelloI have uninstalled the activation key for my Windows 11 computer and have tried to use that key to activate my Windows 11 Pro. The key is not recognized as a valid key. I thought it might not be working because I tried to activate my new OS immediately after uninstalling the key so I waited a couple of days. Still no luck.I thought that I could use my old key for the Pro version. Can this be done or will I need to purchase a new key?Thanks.

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.

 

Lost windows 11 pro ?

Yes, you can upgrade from Windows 11 Home to Windows 11 Pro on your new computer. Since you already have a Windows 10 Pro key that was previously activated on your old computer, you can use that key to upgrade your current Windows 11 Home to Windows 11 Pro.

To do this, follow these steps:

1. Click on the Start button and select Settings (the gear icon).
   
2. In the Settings window, select System.
   
3. In the System menu, choose the "Activation" option.
   
4. Click on the "Change product key" option.
   
5. Enter the Windows 10 Pro product key that you previously purchased and activated.
   

After entering the product key, your system should initiate the upgrade process to Windows 11 Pro. This upgrade process should not require a complete reinstallation of the operating system, and your data should remain intact on your SSD.

It's always a good practice to back up your important data before performing any major system changes, just to ensure that your data is safe in case of any unforeseen issues during the upgrade process. This way, even if there are any complications during the upgrade, you can restore your data from the backup.

Once the upgrade is complete, your Windows 11 Home should be upgraded to Windows 11 Pro, with all your data and applications preserved. You can verify the successful upgrade by checking the system settings or the activation status in the Windows settings.
