GenoPro. I don't use Windows for it, as it's packaged with wine as a snap.

I have a Windows 11 VM which I keep around. I was forced to use it for iTunes because I needed to sync my old photos onto the phone (fortunately a one time process).

I also played around with RemoteApp because I wanted to use Visual Studio or Office on Linux through the Windows VM, but I have not managed to get it working.

I have a Windows computer in the basement to run one program: The virtual cycling platform Zwift.

But someone made a docker image for it, so even that is tenuous. I fired it up on the Linux system I'm typing this on, and it worked fine.

I'm not very familiar with Docker and the like, though. What if the person that created it decides he's no longer interested in maintaining it?

I wanted to do some stress testing on a gaming laptop a while ago and many people recommended OCCT. The laptop was still running Windows at the time, so I tried it and it seems like a good tool. It tests the CPU, RAM, GPU and power supply. I wasn't able to find an equivalent in Linux.

Microsoft Word for my resume. I'm not sure what I can do to change that, I don't want to risk a(n accidentally) badly formatted resume losing me an opportunity...

not for me. Teams can be a web app, packet tracer has a linux version.

Altium

dsa.msc to manage domains.

Printer drivers for high DPI printing.
I'd still have to have a Windows VM even on Windows for this though, as they only work up to Windows 7.

I've never been able to get musicbee working on Linux.

Acrobat Reader. There are a handful of fillable forms that only really work properly in the official Adobe reader.

Exact Audio Copy and Qobuz.

There are none, thankfully. Neither work or home. Last things I've had to emulate were probably done diagnostic or update sw for cars and some ide bundled compiler horror for some old and obscure microcontroller.

Bluebeam

MusicBee and Apple Music.

Apple is Apple so they impose dumb restrictions on the web client like any other streaming platform (and Cider is just a fancy frontend for this), so I have a Windows VM so I get the full experience.

And for MusicBee? Well, the Linux music player situation is... bad, to say the least. There is basically nothing like MusicBee in the Linux ecosystem right now. And every time I went to Reddit to see what people are going to, it's people who are not 100% satisfied with the alternative or Linux users gaslighting them into thinking MusicBee sucks and Their Choice is the Better One. I've tried other players and none of them scratch the itch for MusicBee for me. Quod Libet comes close with its queries, and Tauon looks gorgeous, but I had performance issues with QL for what I wanted it for, and I had issues with Tauon's playlist filtering. And as for WINE? Performance is slow, CJK characters don't show up, and tab dragging results in errors due to WINE not having implemented the functions for it to work. I'm happy to keep a Windows VM for MusicBee.

PKHex, but it runs OK in wine. Little buggy but servicable.

SketchUp. Can't get it to work on Wine.

I use Scrivener for writing. Aside from one or two minor display bugs, it works great on WINE. Switch the UI to GNOME’s Cantrell font and it blends in fairly nicely.

I've been a Linux user for a long time. I started to use a lot of open source free software alternatives because of this, and most of them had Windows binaries.

But I always had a dual boot system only for gaming purposes.

So... I can't think of any software other than games that's educated la Windows only.
