If you’ve been watching Microsoft’s social media accounts on Twitter and Instagram this week, you probably noticed a teaser campaign for Microsoft’s original Windows 1.0 operating system, which was first released in 1985.

It starts out like a one-off joke or maybe a poor attempt at a nostalgic throwback for an OS that never really got much love in the first place:

Running Windows 1.0 in 1985 required at least how much memory? — Windows (@Windows) July 2, 2019

But it soon becomes clear that Microsoft is building up to something...

Something with the signature vibe of Netflix’s popular ‘80s telekinetic bizarro-world mystery series Stranger Things.

Today, the latest tease confirms that it’s indeed a Netflix / Stranger Things tie-in, one that we should expect to come to fruition on July 8th, according to a translation of the Morse code you’ll find at the end of this tweet:

But you know what’s super weird about this? We just watched the entire new season of Stranger Things (it came out yesterday; here’s our review), and nobody uses a Windows PC or even so much as says the word “Microsoft” in the show.

Speaking very optimistically, that could mean we’re getting something special that extends the experience of the show. Or it could easily mean we’re about to be disappointed in Windows all over again. Remember, we’re talking about the company that hired Rachel and Chandler from Friends to introduce Windows 95 to the world.
