For me I got super annoyed by the taskbar not hiding and unhiding correctly. Other one was the search not working correctly on start menu and many times just stalling and nothing happening.

Those were the ones that broke the camel's back.

I'd used Linux a bit out of curiosity in the Windows XP era

Windows Vista came out and was completely unusable on the computers I or anyone around me owned. It was also harder to configure than Linux and the new UI looked worse than the Linux UIs at the time

So I switched and haven't been back to Windows since

Been meaning to make the switch for years now. Was going to do it before Windows 11 either way. Second full screen popup telling me I should switch to Windows 11 I downloaded an ISO, put it on a USB and haven't looked back. NVMe made it that much faster.

I've been playing with Linux distros for over 25 years now. I can't recall what made me go exclusively to Linux,but it had to do with me wanting more control over my devices. I remember that I ended up killing Windows entirely after dual booting 7 (I did not want to move to Windows 10 and EOL for 7 was rapidly approaching) with Linux Mint in 2019 on an Alienware laptop. I started running as much software as I could on Mint, getting to learn LibreOffice pretty well, but I still had to keep a VM for work, as the in-house platform was Windows only.

About 3 years ago my company accepted to provide me with a Windows 365 cloud computer, and I've been solidly using Linux exclusively since then (except for work, but that's going away too as the new platform is fully Web based).

Truth is that I never liked Windows because it's and incredibly intrusive OS, so I have not missed it one bit.

I've played with it for a long time, but I still had a laptop that dual booted Windows. I upgraded the thing to Windows 10, and it became unusable. I went with disabling the anti-virus and firewall. Then I tried to update and the update service didn't work because it tries to go through the firewall service, which is disabled.

I forgot what I did to do that, so my system is essentially broken. I only used Linux on that laptop from then on and only installed Linux on my other machines

Never really have gone full Linux.

I run MacOS, Windows, Ubuntu, Fedora and BSD depending on the need of the box.

The one thing that lead me onto Linux, however, was the full hardware access in Docker.

When I payed a decent amount for logic express and 2-3 years later I couldn't use it with the latest Apple OS.

When Windows 10 came out, half of the Windows 7 system got borked. Mine was one of them.
The next day I flashed Ubuntu on a USB stick

Was curious about the increased customisation so I went dual boot around the time of windows 7.

Went full time Linux when windows 8 came out. Windows has only continued its enshitification since then, so it really paid off.

Every machine I'm currently running would run like dog shit with windows, but runs like brand new with Linux Mint.

When they announced when windows 10 support would end. The writing was on the wall and each update was a toss up whether it would add a useless feature.

I knew from experience many years ago that windows would delete grub if it so much as looked at it funny. So I got an amd card and cut windows out cold turkey.

Linux has a whole host of weird quirks and issues, just like windows. But it's either something documented, fixable, or will be fixed in an update. I'm more excited to click update in Linux than I am with windows too.

Few pieces of software don't work with either wine or a windows VM as backup. But so far I'm not missing much. Missing out on some games because of anti cheat sucks though. Even though I hate anti cheat, I still love a good game of league.

Windows update would always start doing stuff whenever I turned on my PC and would slow it down to a laggy crawl until it finished. This increased the pressing the power button to doing what I need to do time to 15 minutes.

I knew that Linux updates worked differently so I tried it out. And I was right. Oh so right

Windows was actually quite good when I made the swap. It was during the height of windows xp.

I did it because I am a curious guy, and wanted to know what it was all about. I've been full-time and had fun with it since then. :)

Wanted to hack WiFi when i was teenager, right now already close to decade of daily driving linux

I was dual booting Linux and Windows 10 like 4 years ago, and then Windows somehow got rid of GRUB entirely, pissed me off enough to remove Windows, haven't used it on a personal computer since then.

when I realized my hardware no longer worked for me it worked for microsoft and dell and hp etc. I was done.

It happened really slowly for me, over a period of years. We have multiple PCs (several media PCs, a home server, and our personal PCs) that we've built over the years. Aside from our personal PCs, the OS chosen was always just whatever was free to us at the time. Over time this became overwhelmingly Linux. But the real turning point for me at least was the end of 2021.

Our oldest media PC still had Win 7 on it and it was showing it's age. We'd had a lot going on in our lives when Win 7 support ended, and upgrading it was just not a priority until then. Long story short, I put Ubuntu on it.

While I definitely had my gripes about Ubuntu (which caused me to move to Mint a few months later), it was nothing compared to the problems I'd had with Win 10 on my personal machine a couple years prior. Compared to Windows, everything was just so... Easy. I didn't have to fight for my right to just change shit I didn't like. Installing applications was a fucking dream. Most games I cared about playing worked as well or better than they did on Windows.

So I put Mint on my personal machine and never looked back. Moved over to OpenSUSE Tumbleweed a few months after that, but I'm thinking about going back to Mint now that 22 is out.

TL;DR I was real tired of paying for software that would try to tell me what I could and couldn't do. Thought Linux was "too hard," found out it's not (at least for me).

I think it was around the time of the windows 10 beta, I was trying that out and also dual booting with Linux mint.

I remember being a little frustrated with getting games to work great on Linux, but even more frustrated just using Windows. So I thought "Linux makes me less mad, I'm just going to use that"

Nothing really, I started dual-booting and jumped from one to the other depending on what I wanted to do. One day I realized I hadn't booted in Windows for months and had never needed it, so I just got rid of it.
