1. Windows 11 is a performance nightmare, especially on legacy storage
“Windows 11 is just hammering the C: volume like it’s never done before, almost constantly, needing simultaneous reads & writes so much it would have been way more widespread ridicule if most people had not already been on SSDs before W11 ‘accelerated’ the march of sluggishness.” – fuzzfactor
“Just cloning the drive to an old spare SATA SSD that was laying around and that immediately solved the issue. Windows was zippy and very usable again.” – Bluecobra
2. The shell’s shift to web‑based frameworks (React, XAML Islands) is a core pain point
“The start menu is a React app!” – wizzwizz4
“Microsoft is a joke; all of the formerly glorious tech companies are.” – hdrgjkmmn (referring to the React‑based shell)
3. A corporate culture of “vibe coding” and AI‑driven development is eroding quality
“The real culprit was hiring leetcoders in the first place. I genuinely believe the stark decrease in quality of most products across the industry has been driven by that.” – curiousgal
“They’re using llms to code windows. Is that likely?” – bn‑l (and the subsequent discussion about AI‑generated code)
4. Many users are abandoning Windows for Linux (or macOS) because of these issues
“I’m still running Win10 LTSC. No bloat, super fast, still gets security updates.” – Melatonic
“I’ve been on Fedora now for nearly a month and only boot into Windows for work. Eventually, I might get rid of Windows entirely.” – mrcsharp
“I’ve made other choices in recent years… I think this already happened way before but I speculate that the aggressive drive to slop and vibe coding while reducing head count is now coming around to start showing their effects in the software quality.” – samiv
These four themes—performance woes, web‑tech‑based shell, AI‑driven code quality decline, and the migration to alternative OSes—dominate the discussion.
