We've got multiple tools still on Windows 2000, happily running production. They're on an airgapped network though, so no issues.

I would bet there are still a few old pieces of industrial machinery around that I duct taped together by imaging an ancient PC and transferring it to a Virtual Box VM.
There are many, many machines out there running 95 and even earlier versions. The issue is that a machine from 30 years ago is almost always still using the software that came with the machine… 30 years ago.
Even if the OS has received security patches, which isn’t even assured, the company may either no longer be in business, or charge for new OS drivers/specialized software.
In many cases, your options are literally to replace an entire machine worth hundreds of thousands of dollars, or deal with the networking nightmare that is “keep this on the network, but not on the network.”
I use a Windows XP machine for work nearly every day. And yeah, it’s because it runs some of the most expensive equipment in the company.
BART wrote a PDP8 cross assembler in the late 90s, that they still use today.

People keep saying to keep these XP machines off the internet. I seriously doubt there's much threat, especially for even older OS's like 98 and 95. It's the very devil just trying to browse with them, nothing much out there is going to be able to attack them. Security through obscurity indeed!
In any case, we're no longer in the Wild West days when people had machines hooked directly to the internet and a firewall was a third-party addon. LOL, ZoneAlarm anyone!
We all have a basic firewall built into our routers so unless you deliberately expose services you're fairly bulletproof to scanners. I remember scanning for Win2000 machines in blocks of IPs, long after it was defunct. Plenty were out there!
You are forgetting targeted attacks. A blind attack would pretty much not have much of an effect indeed, however if the attacker knows the machine, then it's easy for the attackers to exploit these vulnerability if left "out in the open", and cause havoc, possibly create a lot of damages or leech informations pumped into those machines via old Windows installations.
For a business sure.
You wanna hack my dnd campaign and some pictures of my cock? Sure whatever dude. All financial and important shit goes through my phone anyway and that's likely to be hacked from the institutions I use.
I would totally hang with that lady in the thumbnail lol
My wife still using windows 2000 on her laptop. Still boots and runs. She just doesn't connect it to the internet.

I like the little typo ... c:// :)
Some might be surprised how many systems are still running on AS400s. IBM still makes and maintains IBMi, the modern iteration. My last company wrote our flagship product for these machines, all green screen. Our customers would sometimes move to our GUI product and jump right back to the prompt menus. Hey, if you gotta move fast and have a bulletproof system, text menus are the only way to fly!
By my god, the skill set for running and programming those beasts touches on almost nothing I've learned in 30+ years of IT work. Wish I had got experience in that part of the company, seen some solid job posts for that sorta tech.
I worked in the airline industry for years and learned a GUI overlay for one system and another entirely green screen system called SHARES (see if you can guess the airline). Honestly I kind of enjoyed working with those systems; there's some refreshing "back to basics" feeling kind of like driving a manual transmission.
In my current job I've been using another legacy system. Well, my job was to create a relatively modern service for the legacy system to call, but none of the remaining developers knew how to use the extensions of that system that does SOAP calls. So I had to learn just enough of that legacy system to hold their hands through the parts that call my service. Kind of fun, to be honest!

If not for DX10 and above not even existing on it, afaik, I'd still be using XP. That was the best iteration until they forcibly made you have to upgrade if you played games (especially if you wanted to play Halo on PC).

If it serves their needs then more power to them. Tech companies today more than ever make sure you keep buying.
The dot net framework was ported to Windows 95/98 so they can use more software now.
