Linux

I miss RDP.
Preinstalled in every Windows, just allow access on the host with one click, open it, type in the IP of the remote host, and it's like you're on that pc. Sound, mic, camera, other devices, multiple screens, ... It generally just works.

On Linux with Wayland, I don't even know how or if it works, or how to set it up on the host machine.

Edit: OK, it isn't that difficult, actually:

Games :(

I missed Odin 3 for a few years until I switched to Graphene and never looked back. In tried the FOSS package it didn't work for me and the documentation was beyond my skills at the time.

I miss the stupid people comradery, sometimes. People act funny when you're a normal stupid person and use Linux without the hoodie and a Matrix screen saver.

I'd say a Control Panel, I miss the plethora of authoritive knowledge and settings for every program, device, driver, network, user, and a dozen more things besides, all findable by browsing and not remembering dozens of commands. Of course I'd miss that either way, because Control Panel has been gutted every new version of windows since XP, but it was once nice.

The Start menu context menu, or SUPER+X, is still nice, although mostly for avoiding poor UI choices and slow menus. The fact that many useful options are guaranteed to be there on every windows machine is nice though.

And I would also say Event Viewer, despite how incredibly clunky it is to use. Having one place to check all system logs and track crashes of all kinds was quite useful.

Basically, windows at one point went out of it's way to centralize settings and info, and that's just not possible in Linux without a lot of setup.

Not something I use personally, but a super easy, #JustWorks kiosk mode.

It's the only thing I think Windows does better than Linux.

Don't get me wrong, you can turn Linux into a great kiosk device, but it takes a lot of technical labor.

In the IT space, I often need to set up a basic kiosk device for HR portals, safety training stations, etc. In Windows, this takes 5 minutes tops.

If I had the programming chops, it would be my #1 project to work on. Even if it only worked with a specific DE or distro, I would be alright with that, as long as it was as easy and quick to set up as Windows Kiosk mode.

A minor but useful GUI feature on MacOS in list view is showing the size of directories as well as individual files and being able to sort by those sizes. That extra step in Linux of having to contextually click on a listed directory and choose "Properties" all the way at the bottom of that menu is a minor annoyance

Being able to sync music or movies to my iPhone/iPad. More of an Apple issue than Linux, yet Mac/PC is compatible.

VLC does work, but since it’s not how Apple wants you to use your device it’s not as convincing nor flushed out.

Hardware info (hwinfo) or similar. Be able to check all voltages, speed and temps while testing new hardware. For example my ARC A770 has little to no info, and shows running at pcie x1.

Edit: mistakingly thought link width was x4, but looking at it again shows x1

Game pass

I play and mod a lot of older games most of which aren't on Steam, so getting some of them running takes a bit more manual effort especially if they require a 3rd party patch to run on modern hardware.

Normally it's pretty simple like declaring some extra DLL files, But sometimes I'm jumping through hoops trying to get some old installer than hasn't been updated since 2009 to run...

I've had more success than failures though, Wine is pretty amazing imo.

Bansi Buddy and NetZero of course!

But really it's winamp, which of course I would still use on Linux except I've become a disciple of the streaming gods.

I miss the human connection with those around me who use windows. After years of using Linux almost exclusively, I now miss being able to relate to them. Sometimes I feel lonely because of it.

Colleagues get to resonate with all the windows slowness and reliability issues, and I can only stay silent.

"Hey, how can I do this obscure thing?" "Oh yes that's easy... err... no, I don't know." So many methods that are easy on Linux are basically impractical on windows. E.g. many text file processing tasks are doable swiftly with simple shell scripts or even bash one-liners; what will a windows user do? Telling them to automate something means suggesting them to create a new Java project. Opening an SSH session means using Mobaxterm which limits the number of sessions you can create.

Desktop session restore. Shut down pc, turn back on, everything like when shut down. Or on crash, sometime even kernel panic, restart and right back to work.

Foobar2000. Haven't found anything similar in terms of ui customization options, easy convert and ReplayGain operations built in.

Been on Linux since 2007, so for me it's kind of the opposite. You just get settled with your OS after a while, you're used to how it works.

For me the immediately missing features is customizability in window management. I'm not a tiling fan, but I still miss basic convenience features like middle click paste, press alt and drag windows around or press alt and right click to resize windows from whichever side is the closest to the cursor. The different way it arranges windows (Linux tries hard to make them fit in unused space whereas Windows just opens it in the middle of the screen). Another big one is if you have a window focused and try to scroll another window in the background with your mouse cursor over it, it'll still scroll the focused window even though the mouse cursor isn't on it. Focus steal prevention is non-existent so if you're typing and another window pops open, it steals your keyboard input. The search bar is like, utterly useless, so is the Microsoft Store. The start menu doesn't open instantly like it has to load it every time. When you uninstall something there's still leftover crap of it everywhere.

Thankfully when it comes to Linux apps, their open nature means the majority of them just have Windows builds anyway, and what doesn't would work in WSL. So really all I can miss is the inherent flexibility and openness Linux gives me.

Ive been mostly on linux for like 25 years, but i was using a chromebook for a while bc it was cheap (had a linux desktop tho).

I miss easily running android apps on my laptop. I could install waydroid but its not that big of a deal to me. Just the only thing i could think of that i miss from another os...
