I have upgrade from Samsung Galaxy S10 to S22 Ultra for some time now. S Pen also become one of the tools that I use in my daily life and because of this, I also used Samsung Note. I am also using Windows 11 and the app was not available to download.
Here is the solution I use. Simply open Command Prompt & type: winget install "Samsung Notes". Agree to the prompts by typing “Y” and finally installed Samsung Notes without issue on my Windows 11.
