For IE versions the support windows have always been "X years since release (or perhaps X years since the next version), or until all Windows variant released with it are EOL". If Win10 is indeed evergreen, then that second part will never expire. Perhaps they'll count the biannual Windows feature updates instead of Win10 as a whole, and so count it from when they stop releasing install media with IE11 on them, but as that hasn't happened yet, we'll still be some years away for IE11 stopping. Even then '11 will still be around in some environments for a while after EOL.

We only recently got rid of IE8 support for some of our clients as they stopped using it. That was mainly because of the then upcoming EOL of IE8 in sync with the EOL of Win7/Win2008 (the last versions released with IE8). I hear some are not so lucky... I expect IE11 to be a problem (though an increasingly small one, thankfully) for some time to come.

In any case, can you link (or screenshot if it doesn't cooperate with deep linking) to an official page listing 2025? I'm not seeing that.

>Internet Explorer is a component of the Windows operating system and the most current version will continue to follow the specific lifecycle policy for the operating system for which it is installed. To find the lifecycle dates for all operating systems, search the Microsoft Lifecycle Database here.

It's unknown how long MSFT will continue to include IE in Windows, but at the very least it will be supported until January 2029, according to https://en.wikipedia.org/wiki/Windows_10_version_history.
