Microsoft's recent release of the Cumulative Update Preview for Windows 11, labeled as KB5030310, has been identified to alter the functionality of AMD's Adrenalin graphics control panel. According to a community post on AMD forums, after installing this update, the Adrenalin graphics control panel reverts custom settings back to default upon every system reboot.

This specifically refers to hard reboots, where drivers are reloaded and new user sessions begin, rather than quick startups. While the core graphics driver functionalities remain unaffected by this update, the resetting of user custom settings in the control panel could be of concern, especially for users who modify and rely on these settings. Feedback from the AMD community has highlighted that several users are facing this after the Windows update installation.

For users who stick to default settings on their graphics card, this change may not be noticeable. However, those who engage with advanced AMD features, including Hyper RX, Anti-Lag, Radeon Boost, or RSR, might find the resetting particularly inconvenient.

Alongside this, Microsoft's KB5030310 update brings multiple bug resolutions for Windows 11. These cover issues related to Excel, the Korean touch keyboard, search box tooltip, search button, sleep mode, and synchronization with iCloud Calendar and Contacts. A detailed breakdown of these adjustments is available in Microsoft's official patch documentation.

Radeon GPU users might consider holding off on installing this update. If already updated and facing the described issue, uninstalling the update could be a remedy. It's essential to understand that the problem's confirmation primarily stems from the mentioned AMD forum post, implying that not all Radeon users may experience this issue. It's anticipated that AMD might release a software update addressing this before any subsequent Windows 11 patch.
