Source? According to microsoft:
>Please note that the Internet Explorer (IE) 11 desktop application will end support for certain operating systems starting June 15, 2022
>Customers are encouraged to move to Microsoft Edge with IE mode. IE mode enables backward compatibility and will be supported through at least 2029. Additionally, Microsoft will provide notice one year prior to retiring IE mode.
Your best bet right now for IE 11 is an installation of windows server 2022, which contains IE 11 and will be supported till Oct 14, 2031. Still, it's unknown whether IE 11 would be supported by then.
