Major Features in 24H2
AI Integration with Copilot
Copilot now sits directly in the Windows 11 taskbar. You can ask it to summarize documents, generate images, or troubleshoot PC problems. The AI assistant works offline for basic tasks if you have an NPU (Neural Processing Unit) chip.
Copilot remembers your preferences across sessions. It suggests actions based on your usage patterns. For example, it might recommend closing unused apps when your RAM runs low.
HDR Background Support
Windows 11 Version 24H2 applies HDR to your desktop wallpaper. Previously, HDR only worked in supported apps and games. Now, your home screen looks richer with deeper blacks and brighter highlights on compatible monitors.
This feature requires an HDR-capable display. The system automatically adjusts based on your monitor’s capabilities.
Wi-Fi 7 Support
Microsoft added native Wi-Fi 7 support. This new wireless standard delivers speeds up to 46 Gbps, significantly faster than Wi-Fi 6E. You’ll need compatible hardware to use this feature.
Wi-Fi 7 reduces latency for gaming and video calls. It also improves performance in crowded networks with many connected devices.
Energy Saver Mode
The new Energy Saver replaces Battery Saver. It works on both laptops and desktops. When enabled, it dims your screen, limits background apps, and reduces system performance slightly to save power.
You can customize which features Energy Saver affects. This gives you control over the balance between performance and power consumption.
File Explorer Updates
File Explorer got a visual refresh. The interface now includes a modern address bar with breadcrumb navigation. Archive file support expanded to include 7z, tar, and gz formats without third-party tools.
Tabs in File Explorer work smoother. You can drag and drop files between tabs more reliably than in 23H2.
Known Issues and Problems
USB Audio Device Failures
Users report USB audio devices stopping randomly. This affects external sound cards, microphones, and headsets. Microsoft acknowledged the bug in November 2024 but hasn’t released a permanent fix.
Temporary workaround: Unplug and reconnect your USB audio device. Some users fixed it by disabling USB selective suspend in power settings.
Blue Screen Errors
Some PCs with older Intel processors experience Blue Screen of Death errors. The issue appears most often on 7th and 8th generation Intel chips. Microsoft released a patch in December 2024 that reduced these crashes by 60%.
Gaming Performance Drops
Certain games show lower frame rates after updating to 24H2. Reports indicate up to 15% performance loss in titles like Fortnite and Valorant. The problem seems related to a Windows security feature called Memory Integrity.
Disabling Memory Integrity in Windows Security settings often restores performance. However, this reduces your system’s protection against certain attacks.
Installation Failures
Clean installs sometimes fail at 95% completion. The error message “Windows could not complete the installation” appears without a clear explanation. This happens more frequently on systems with dual-boot configurations.
Compatibility Blocks
Microsoft blocked the update on PCs with specific hardware. Devices with certain Intel Smart Sound Technology drivers can’t install 24H2. Western Digital SSDs using particular firmware versions also face installation blocks.
How to Install Windows 11 Version 24H2
Check Compatibility First
Open Settings, go to Windows Update, and click “Check for updates.” If your system qualifies, you’ll see the 24H2 update listed. Microsoft rolls out updates gradually, so you might wait weeks before it appears.
Verify your PC meets minimum requirements:
- TPM 2.0 enabled
- 4GB RAM minimum (8GB recommended)
- 64GB storage space
- UEFI firmware
- Secure Boot capable
Backup Your Data
Create a full system backup before updating. Use Windows Backup or third-party software like Macrium Reflect. Save important files to external storage or cloud services.
System restore points don’t always work after major updates. A complete backup gives you a safety net if something breaks.
Installation Methods
Windows Update: The safest method. Go to Settings > Windows Update > Check for updates. Download and install when available.
Installation Assistant: Download from Microsoft’s website if Windows Update doesn’t show the update. This tool forces the installation on compatible systems.
Media Creation Tool: Create bootable USB for clean installs. This method works best for fixing corrupted systems or upgrading from Windows 10.
Installation takes 30 to 90 minutes, depending on your hardware. Your PC will restart several times during the process.
Should You Install 24H2 Now?
Who Should Update
Update if you need specific features like Wi-Fi 7 or improved Copilot. Business users requiring enhanced security features benefit from immediate installation. Gamers with newer hardware (2022 or later) typically see performance gains.
Who Should Wait
Hold off if you rely on USB audio devices for work. Users with 7th or 8th gen Intel processors should wait until Microsoft releases more stability patches. Competitive gamers might delay updating until performance issues get resolved.
