Windows 8 Upgrade Streamlined to 11 Clicks

For those who upgrade between succeeding versions of Microsoft Windows, the upgrade installer can be cumbersome. There are way too many prompts and clicks. Microsoft is working to make the upgrade package of its next major version of Windows, for now referred to as Windows 8, streamlined to as few as 11 clicks. The new installer will be designed to perform most of its tasks without needing user input.

Microsoft will implement a new web-delivery method, where you purchase your Windows 8 license online, and the installer downloads your soft copy to you. It is pre-fed with your 25-character product key. Microsoft's next major Windows release is slated for 2012.

Upgrade Windows 11 Pro

I am sorry , I am not so sure about your issues, but for Microsoft Surface device , it is normally preinstall with Windows 10/11 S mode , you need to first switch the S mode to Home version , then you can use the windows 10/11 Pro key to upgrade from windows 10/11 Pro version, here is the steps

Switch from windows 11 S to Home :

1. open Settings > System > Activation.
   
2. In the Switch to Windows 11 Pro section, select Go to the Store. (If you also see an "Upgrade your edition of Windows" section, be careful not to click the "Go to the Store" link that appears there.)
   
3. On the Switch out of S mode (or similar) page that appears in the Microsoft Store, select the Get button. After you see a confirmation message on the page, you'll be able to install apps from outside of the Microsoft Store.
   

Upgrade from Windows 11 Home to Pro:

Upgrade directly from Microsoft store is for $99.99USD, but you can get a windows 11 Pro key from the Microsoft partner online store keyingo, it is cheaper but genuine too

 

Windows 11 Pro Upgrade from Windows 10 Pro Edition

No but after it installed the malfunctioning Windows 11 upgrade it was listed as Windows 11 Pro. Microsoft Windows support advised I reinstall Windows 10 Pro and said that Windows 11 is really only meant for new PC's that come with it preinstalled. MSI website doesn't list my 2020 GT76 Titan dt-039 notebook on their Windows 11 upgrade eligibility list so I guess that's why the Windows 11 Pro upgrade failed. I suggest being careful with trying the Windows 11 upgrade despite it stating my notebook was capable of running Windows 11 it was wrong. Luckily I have the original Windows 10 Pro USB Flash drive because the Windows 11 Pro upgrade was so incomplete I had no way of reverting notebook back to Windows 10 without reinstalling from a USB Flash.
