Windows 11 has officially signed the death sentence for Internet Explorer as it will be disabled when users upgrade to the new operating system. Microsoft announced in May that Internet Explorer would reach the end of support on June 15th, 2022, for certain versions of Windows 10. Microsoft Edge now includes the IE Mode feature that opens a website in a legacy rendering engine to work correctly. It is not clear if Microsoft will accelerate the retirement of Internet Explorer in Windows 10 as well. Users will know they are in IE Mode as a little Internet Explorer icon will appear in the address bar.
