Hello.
Before upgrading to Windows 11 you should read The List of features removed in Windows 11
And you should also check your computer using the health check tool:
https://aka.ms/GetPCHealthCheckApp (Direct link warning)
If you can't directly update to Windows 11 with Windows Update, use the Windows 11 Update Assistant:
https://www.microsoft.com/en-us/software-download/windows11
To download & use this tool, you need to expand the "Before you begin" thing under "Windows 11 Installation Assistant" and read it, then click the "Download Now" button, then launch the EXE file and you will be guided to install Windows 11.
