Windows 11 is Microsoft's most significant desktop operating system release in over half a decade. First made available in October 2021, it introduces a refined visual language, tighter hardware requirements, and a set of productivity-oriented features aimed at both consumer and enterprise users. This post summarizes the key changes and what they mean in practice.
The most immediately visible change is the centered taskbar and Start menu, departing from the left-anchored layout that Windows has used since Windows 95. App icons are grouped in the center, giving the desktop a cleaner, more symmetric look. The Start menu itself no longer shows Live Tiles; instead, it presents a grid of pinned apps and a "Recommended" section powered by recent file activity.
Window management has also improved. Snap Layouts allow users to quickly arrange open windows into predefined grid configurations by hovering over the maximize button. Snap Groups remember those arrangements, so switching between tasks and returning to a previous layout is faster than before.
Windows 11 raised the hardware bar compared to Windows 10. The most debated requirements are the mandatory TPM 2.0 chip and the processor allowlist, which excludes many pre-2018 CPUs. Microsoft's rationale centers on security — TPM enables features like Secure Boot and hardware-backed encryption by default.
| Component | Minimum requirement |
|---|---|
| Processor | 1 GHz, 2 cores, 64-bit (approved list) |
| RAM | 4 GB |
| Storage | 64 GB |
| Firmware | UEFI, Secure Boot capable |
| TPM | Trusted Platform Module 2.0 |
| Display | 720p, 9” or larger, 8 bpp color |
Security is the central theme of this release. Beyond TPM and Secure Boot, Windows 11 enables Virtualization-Based Security (VBS) and Hypervisor-Protected Code Integrity (HVCI) by default on supported hardware. These technologies isolate sensitive processes from the rest of the OS, significantly raising the bar for kernel-level exploits.
Windows Hello multi-factor authentication is now more deeply integrated, and Microsoft Defender has received updated behavioral detection to address fileless malware and supply-chain attack vectors.
Windows 11 ships with several workflow improvements worth noting:
On qualifying hardware, Windows 11 delivers performance comparable to Windows 10. Boot times are similar, and Microsoft has made optimizations to foreground app prioritization — the OS deprioritizes background processes to keep active windows more responsive. That said, the increased RAM baseline (4 GB minimum, 8 GB recommended) means older budget machines may feel constrained.
For users on supported hardware, the upgrade from Windows 10 is free and largely seamless. The new interface takes a short adjustment period, but the security improvements alone make it worthwhile for anyone who keeps sensitive data on their machine. Enterprise environments should evaluate driver and application compatibility before a broad rollout, as some legacy software may not be fully tested against the new OS.
Windows 10 continues to be a solid choice for machines outside the compatibility envelope, at least until its end-of-support date in late 2025.
