In abstract:
- PCWorld experiences that Home windows 11 nonetheless depends on code from the Nineties, notably the Win32 API from Home windows 95, for primary capabilities like right-clicking.
- Microsoft CTO Mark Russinovich acknowledges the surprising longevity of this legacy code, which stays basic to many purposes and core Home windows operations.
- Earlier makes an attempt to modernize the Home windows API, together with WinRT, failed to completely change the enduring Win32 system that continues powering immediately’s working system.
Home windows 11 is essentially the most fashionable, safe, and up to date Home windows ever—not less than that’s what Microsoft retains saying. However a senior Microsoft government lately revealed simply how a lot of the underlying expertise in Home windows 11 remains to be legacy, all the best way from a long time in the past.
One such relic in Home windows 11 comes into play everytime you right-click a file or launch a desktop app. Once you carry out such duties, you’re executing code that was written within the Nineties.
We’re speaking concerning the Win32 API, for which Microsoft nonetheless maintains a programming reference help doc. Though the Win32 API turned widespread with Home windows 95, it had already been carried out in Home windows NT previous to that. (See our visible tour of Home windows by means of historical past!) However the shocking revelation right here is that Microsoft by no means deliberate for this API to remain related for therefore lengthy.
Mark Russinovich, Chief Know-how Officer of Microsoft Azure and founding father of Microsoft Sysinternals, explains in a video posted to social media by the Microsoft Dev Docs account:
Did anybody count on Win32 to nonetheless be going robust in 2026? Mark Russinovich explains why its deep roots in Home windows—and the large ecosystem constructed on prime—have given it severe endurance. Seems “legacy” can nonetheless imply important.

Russinovich explains how nobody anticipated Win32 to have such a long-lasting legacy and why he believes it’s nonetheless so vital immediately:
Did anybody within the 90s count on Win32 to nonetheless be a first-class API floor within the yr 2026? And I feel I can safely reply, “No.” No person, I feel, would’ve anticipated that as a result of we had been considering flying vehicles and moon stations by the yr 2026. Not Win32 that was designed again in Home windows 95 days. I feel one of many causes it’s obtained this endurance is only a basic layer within Home windows that so many apps have constructed on—so many applied sciences and ecosystems have been constructed on prime of—that it’s sort of bedrock.
Russinovich continues:
Now, I feel that there’s been varied instances in Microsoft’s historical past the place we thought we’d reboot the Home windows API floor, like WinRT, that really didn’t play out the best way lots of people anticipated it to, given nonetheless the separation between the shopper, Win32, and the browser (HTML and JavaScript).
He ends the video speaking about just a few different instruments that had been written a long time in the past but nonetheless reside on, together with Sysinternals, Sysmon, and ZoomIt. Study extra about why Sysinternals is nice for Home windows troubleshooting and the way Sysmon is being added instantly into Home windows itself.
