What the AMD 26.6.2 Windows 10 Driver Bug Does
AMD’s Windows 10 driver bug is a compatibility failure in AMD Software: Adrenalin Edition 26.6.2 that causes Radeon GPUs to trigger a Code 43 yellow bang error, fall back to the Microsoft Basic Display Adapter, and block access to Adrenalin and features such as FSR 4.1 on affected systems. After installing this AMD driver on Windows 10, many Radeon owners see AMD Software refuse to launch with a warning that the current AMD software version is not compatible with the installed graphics driver. In Device Manager, the GPU shows a yellow exclamation mark and the system loses hardware acceleration, so games and 3D workloads perform poorly or fail to start. Reports focus on the RX 7000 series, though some RX 9000 and older Radeon cards are also affected, while Windows 11 systems are not.
How to Confirm You Have the Yellow Bang Code 43 Problem
Before applying any Radeon GPU troubleshooting steps, confirm that the AMD driver Windows 10 issue is the 26.6.2 yellow bang error. Open Device Manager and expand “Display adapters.” If you see your Radeon GPU with a yellow exclamation mark, right‑click, choose Properties, and check the Device status field for a Code 43 message. At the same time, try launching AMD Software: Adrenalin Edition from the Start menu. Affected systems usually display an incompatibility warning and close. According to Technobezz, the 26.6.2 update “triggers a Code 43 error in Windows Device Manager, flagging the GPU with a yellow bang and forcing the system to fall back to the Microsoft Basic Display Adapter.” If this matches what you see, you are dealing with the same bug and should either roll back to 26.6.1 or move to AMD’s 26.6.3 hotfix.
Rollback Method 1: Revert to AMD Adrenalin 26.6.1 for Stability
If you want the fastest Code 43 error fix with minimal changes, roll back from 26.6.2 to AMD Software: Adrenalin Edition 26.6.1. AMD initially recommended this as a “temporary workaround” for Windows 10 users facing the yellow bang error and failed launches. First, download the 26.6.1 installer from AMD’s official driver page but do not run it yet. Then open Apps & Features, uninstall “AMD Software: Adrenalin Edition,” and select the option to remove driver components. Reboot when prompted. After Windows restarts, run the 26.6.1 installer and choose Factory Reset only if you are comfortable wiping existing settings. Once installation finishes and you reboot again, confirm in Device Manager that the yellow bang is gone and the GPU is functioning. Note that this fixes stability but removes FSR 4.1 support on RDNA 3 GPUs.
Rollback Method 2: Use AMD Cleanup Utility Before Installing 26.6.3
For a cleaner Radeon GPU troubleshooting process, especially if you tried 26.6.2 multiple times, use the AMD Cleanup Utility before moving to a safe driver. Download the AMD Cleanup Utility from AMD’s support site, then boot into Windows Safe Mode if possible. Run the utility and allow it to remove all AMD graphics drivers and software, then reboot when it finishes. At this point your system will use the Microsoft Basic Display Adapter but should no longer carry old driver remnants. Now you can decide: either install Adrenalin 26.6.1 for proven stability, or go straight to the new 26.6.3 Hotfix Preview if your card is in the RX 7000 series or newer. Wccftech notes that AMD “recommends downgrading to an older version using the AMD Cleanup Utility” if 26.6.2 remains installed and problematic.
Install AMD’s 26.6.3 Hotfix to Restore FSR 4.1 on Windows 10
AMD has now released Adrenalin Edition 26.6.3 Hotfix Preview to solve the Windows 10 compatibility problem and restore FSR 4.1 support on RDNA 3 GPUs. Overclock3D reports that the hotfix “fixed intermittent install issue seen when installing AMD Software: Adrenalin Edition 26.6.2 on Windows 10 systems for Radeon RX 7000 series and above graphics products.” After cleaning 26.6.2 with either the standard uninstaller or AMD Cleanup Utility, download the 26.6.3 Hotfix Preview for Windows 10 64‑bit 21H2 and later from AMD’s site. Run the installer, follow the prompts, and reboot. Then open Device Manager to confirm the yellow bang error is gone and check Adrenalin’s About page to verify you are on 26.6.3. With this driver, RX 7000 series users regain FSR 4.1 support and should see normal performance in supported games.
