Microsoft has identified that RGB lighting device drivers may be causing severe gaming crashes and system restarts following the August 2026 Windows updates.

  • Recent Windows updates (KB5121003) are causing game crashes and system reboots.
  • The issue is linked to drivers from RGB-enabled peripherals, specifically involving 'inpoutx64.sys'.
  • Affected titles include ARC Raiders, MARVEL Tōkon: Fighting Souls, and The Finals.
  • Embark Studios has provided an unofficial workaround involving driver removal.
  • In a significant update regarding Windows stability, Microsoft has announced that ongoing gaming issues—ranging from game crashes to unexpected system restarts—may be linked to RGB lighting peripherals. This investigation follows reports of instability after the release of the August 2026 Windows updates on systems running Windows 11 24H2 and 25H2.

    The Root of the Conflict

    According to Microsoft's release health dashboard, the problem stems from drivers or code components installed by RGB devices. These components often use file names similar to 'inpoutx64.sys'. The latest Windows update appears to have created a conflict between these specific device drivers and the way certain games interact with the Windows kernel, leading to critical errors like 'EXCEPTION_ACCESS_VIOLATION'.

    Developer Response and Workarounds

    Embark Studios, the developer behind high-profile titles like The Finals and ARC Raiders, has been proactive in addressing the crisis. They confirmed that the crash is directly related to the 'inpoutx64.sys' file, which was altered by the recent Windows update. Until a formal patch is deployed by Microsoft, Embark has suggested a manual workaround: users may need to delete the specific service and remove the driver file from the Windows drivers folder to restore stability.

    The conflict between specialized hardware drivers and core OS updates highlights the fragile ecosystem of modern PC gaming.

    Why This Matters

    BozokMedia analysis shows that this issue underscores the growing complexity of Windows kernel management. As more peripherals integrate deep-level software for lighting effects, the surface area for driver conflicts increases, potentially compromising the stability of the entire OS for high-performance users.

    Historical Context of Update Failures

    Microsoft has a history of managing such compatibility hurdles. In October 2024, they had to block updates to prevent Asphalt 8 crashes, and in early 2025, they addressed bugs in the Auto HDR feature that affected Windows 11 users. This pattern suggests that as Windows evolves, maintaining legacy hardware compatibility remains a persistent struggle.

    Did You Know?: RGB controllers often operate at the 'Kernel level,' meaning they have deep access to your computer's brain, which is why they can cause total system crashes.

    Frequently Asked Questions

    Question 1: Which games are most affected by this bug?
    Answer: Currently, games like ARC Raiders, MARVEL Tōkon, and The Finals are reporting significant issues.

    Question 2: Will a driver update for my mouse/keyboard fix this?
    Answer: It depends on whether the manufacturer updates the driver to be compatible with the new Windows kernel; a Microsoft OS patch is the most likely permanent fix.
