Dear Casey,
You’re right—the date quoted in the article has already passed. I checked the Microsoft Learn page, and it still states that new lab versions will be published on or before August 15, 2026. That statement alone does not confirm whether an updated kit has been released.
As a community member, I don’t have access to the team’s release schedule, so I can’t confirm a replacement date. Please use “Suggest a fix” at the bottom of the article to flag the outdated deadline and request clarification. You can also follow the article’s “Download the Windows 11 and Microsoft 365 lab kit” link to check the current offering.
If this helped, I’d appreciate a Like so others can find the answer more easily.
