Windows 11 24H2 (the 2024 Update) brings a mix of AI-focused features for Copilot+ PCs and quality-of-life improvements for everyone: better File Explorer, new energy saver, Wi-Fi 7 support, small but useful UI tweaks and a new “checkpoint” update model.
Updating is generally safe if your hardware meets Windows 11’s requirements, your disk isn’t full and you’ve backed up your important files.
If your current Windows build is unstable or heavily modified, doing a clean install with a genuine Windows 11 key is often the best way to enjoy 24H2 with fewer issues.
What’s new in Windows 11 24H2?
You don’t have to list every build number, focus on what users feel:
- General improvements for all PCs
- File Explorer UI refinements and performance tweaks.
- Start menu improvements and better account management cards in Settings.
- New energy saver controls for better battery life on laptops.
- Wi-Fi 7 and Bluetooth LE Audio support on compatible hardware.
- More polished quick settings and notifications.
- AI and Copilot+ (for supported devices)
- Deeper Copilot integration and new AI-powered experiences (Recall, enhanced editing tools, etc.) on Copilot+ PCs.
- For non-Copilot+ hardware, Copilot behaves more like a standalone app or web experience rather than a fully integrated “AI layer”.
- Deeper Copilot integration and new AI-powered experiences (Recall, enhanced editing tools, etc.) on Copilot+ PCs.
- Checkpoint cumulative updates
- Updates are reorganised so that later updates can be smaller and faster to install, as long as you’ve installed key “checkpoint” updates along the way.

Pre-update checklist for Windows 11 24H2
Before you hit “Download and install”:
- Check hardware compatibility
- Make sure your PC meets Windows 11 requirements (CPU list, TPM 2.0, Secure Boot, RAM, storage).
- If you’re unsure, run PC Health Check → link to your requirements article.
- Back up important data
- Use OneDrive, an external drive or a NAS to back up documents, photos, and any irreplaceable project files.
- For critical setups, create a full system image.
- Free up disk space
- Ideally have at least 20-30 GB free on the system drive.
- Clean old Windows update files and temporary files.
- Update drivers and firmware
- Install pending OEM BIOS/UEFI updates and GPU/chipset drivers.
- This reduces the chance of driver-related crashes after the update.
How to install Windows 11 24H2
Method 1: Windows Update (recommended)
- Go to Settings → Windows Update.
- Turn on “Get the latest updates as soon as they’re available”.
- Once 24H2 is offered, click Download and install, then follow the prompts.
Method 2: Installation Assistant / ISO
- For unsupported timing (or clean installs), use Microsoft’s Installation Assistant or official ISO.
- Do not rely on third-party tools that modify installation files; they can cause activation and stability issues.
This is a good place to mention that if you’re doing a clean install, you should have a genuine Windows 11 key ready → internal links to Windows 11 Keys and Windows 11 Pro (Retail).
After the update: quick sanity checks
- Confirm Windows is activated (Settings → System → Activation).
- Test Wi-Fi, audio, GPU and peripherals to catch driver issues early.
- Run Windows Update again to pull any post-24H2 patches.
- If you’re seeing constant crashes or weird bugs, consider a clean install instead of fighting a broken in-place upgrade.
FAQ
Is Windows 11 24H2 mandatory?
Eventually, yes: older Windows 11 versions fall out of support, and you’ll need 24H2 or later to keep receiving security updates.
Do I need new hardware for 24H2?
If you already run a supported Windows 11 build, you generally don’t need new hardware, but very old systems that barely met requirements may struggle, especially with newer AI features.
Can I roll back if I don’t like it?
For a short time after upgrading, Windows keeps your old build in a backup folder so you can roll back. After that window closes, the only way back is a clean reinstall.
Do I need a new product key for 24H2?
If you’re upgrading an already activated Windows 11, you usually keep your activation. You’ll typically need a new key only for fresh installs or big hardware changes.
