Unofficially, Pros (Why people love it) 1. No forced feature updates You never wake up to “We’re updating your system” without consent. Updates are only security patches — fast, predictable. 2. Extremely stable Since Microsoft isn’t adding new features, regressions are rare. Once stable, it stays stable for years. 3. Bloatware-free No Candy Crush, Xbox ads, OneDrive nagging, weather bar, or news feed. Start menu is clean. 4. Lightweight on resources On a fresh install, it uses ~1.2–1.5 GB RAM idle (vs 2.5–3 GB for Windows 11 or standard 10 Pro). Disk space ~10-12 GB vs 20-25 GB. 5. Long support lifecycle 5 years mainstream + 5 years extended = 2032 end-of-life . Perfect for machines you don’t want to touch for 5+ years. 6. Works with all regular Win32 software Games (Steam, Epic), Adobe, Office, DAWs, drivers — everything that runs on Windows 10 runs here. Cons (Real drawbacks) 1. No Microsoft Store by default If you need Store apps (e.g., Netflix, WhatsApp Desktop, Dolby Access, some gaming services), you must manually install the Store using a PowerShell script (possible but not official for non-enterprise). 2. No feature updates means no new features Ever. No WSL improvements after 21H2, no new task manager, no clipboard history enhancements, no new Windows Terminal built-in (you can install manually). 3. Hardware support may lag Very new CPUs (13th/14th gen Intel, Ryzen 8000 series) work, but newer chips may lack official driver optimization for 21H2. Most drivers fine, but some Wi-Fi 7 or USB4 controllers might have issues. 4. Not legally for home users Licensing-wise, LTSC is sold only through Volume Licensing to businesses. Many home users activate via KMS or buy keys from third-party resellers — but those keys are often gray-market (MAK keys resold illegally). Microsoft doesn’t provide a legal retail path for individuals. 5. No support for some development tools Latest .NET or Visual Studio features might require newer Windows builds, but 21H2 is still largely fine through 2025. 6. Manual installation of modern Edge Out of the box, it has old Edge (HTML/JS-based). You must download Edge Chromium manually — fine for most, but a small annoyance. Performance comparison (real-world) | Metric | Win 10 Pro 22H2 | Win 10 LTSC 2021 | Win 11 Pro 23H2 | |--------|----------------|------------------|------------------| | Idle RAM | ~2.1 GB | ~1.3 GB | ~3.0 GB | | Background processes | ~110 | ~70 | ~130 | | Boot time (SSD) | 14 sec | 11 sec | 16 sec | | Game FPS difference | Baseline | +2–5% | -0–3% |

If you want a Windows 10 that behaves like Windows 7 — stable, predictable, no ads, no surprises — and you’re comfortable with manual setup and no new features, LTSC 2021 is the best Windows edition Microsoft has made in a decade. en-us_windows_10_enterprise_ltsc_2021_x64

If you need the latest gaming optimizations, new Windows features, or a legally straightforward license, stick with Windows 10 Pro or Windows 11. Unofficially, Pros (Why people love it) 1
