Microsoft has implemented a block on Windows 11 24H2 upgrades for systems with Auto HDR enabled, following reports of significant gaming compatibility issues. The problem affects the Auto HDR feature, which automatically enhances color range and brightness in games on HDR-capable displays.

Users have reported multiple issues, including:
– Game freezes and crashes
– Incorrect color display
– Oversaturated and high-contrast graphics

Microsoft’s Temporary Solutions:
1. Disable Auto HDR through Settings > System > Display > Graphics
2. Turn off Auto HDR globally or for specific games using Custom settings
3. Compatibility hold (safeguard ID 55382406) placed on affected devices

The company advises against manual updates using the Media Creation Tool or Windows 11 Installation Assistant until the issue is resolved.

This follows recent Windows 11 24H2 compatibility holds due to:
– Ubisoft game crashes (recently resolved)
– Outdated Google Workspace Sync conflicts
– Intel Smart Sound Technology driver incompatibilities causing BSODs

Users experiencing these issues should wait for official fixes before attempting to upgrade to Windows 11 24H2.
