Remember Internet Explorer 10? Your SysAdmin does.
Released all the way back in 2012 (!), the ill-fated browser will finally meet its end in January 2020, alongside Windows 7. But while Microsoft will allow you to pay for patches to Win7 if you absolutely insist on continuing to run it (this'll be slow-moving businesses rather than individuals), IE10 is gone. Kaput. Donezo. Get over it.
The beleaguered browser was originally scheduled to expire in 2018, but got a two-year extension thanks to people who insisted that six years to stop using a bad product wasn't enough time.
In case you've forgotten how long ago 2012 was in software years, just look at this screenshot from when IE10 was new:

If your work computer still looks like that, you need a new job.
Seriously though, there are reasons some places are still using IE10. Everyone who's ever worked for a company that doesn't put time or love into its IT resources knows the pain of having to use ancient, shonky software to access some necessary function of a custom program that was made by some guy who has long since retired on a pile of money.
Companies still using Windows Server 2012 will be able to update to Internet Explorer 11 and use that instead, or you can upgrade properly to Server '16 or '19. We're not sure many companies who've stuck with IE10 this long will take the latter option, but Microsoft can hope. [The Register]
