This tutorial will show you how to disable the "Microsoft Edge is no longer supported on this version of Windows" warning for all users in Windows 7 and Windows 8/8.1.
Microsoft Edge reached end of support for Windows 7 and Windows 8/8.1 on January 10, 2023.
You will now always see a "Microsoft Edge is no longer supported on this version of Windows. Upgrade to Windows 10 or later to get regular feature and security updates from Microsoft Edge." warning at the top of Microsoft Edge by default.
You can close the unsupported OS warning for the current session of Microsoft Edge, but it will just show again the next time you reopen Microsoft Edge.
