Microsoft Rolls Out Fix for Windows 11 Crashes & Gaming Issues — US Users

Introduction

Microsoft has started rolling out a permanent fix for a known issue causing system crashes and gaming problems on Windows 11 devices. US users running Windows 11 24H2 and 25H2 have been experiencing EXCEPTION_ACCESS_VIOLATION errors, games failing to launch, and system freezes.

The fix, which began rolling out on August 26, 2026 at 6 PM PT, targets a problematic driver called inpoutx64.sys that was causing conflicts with certain games and RGB lighting peripherals. This is welcome news for the millions of US consumers and businesses affected by these frustrating issues.

What Is the Windows 11 Crash Issue?

US users running Windows 11 24H2 and 25H2 have reported several frustrating problems:

• System crashes — random system freezes and blue screen errors
• Games failing to launch — popular titles like ARC Raiders, MARVEL Tōkon: Fighting Souls, and The Finals were affected
• EXCEPTION_ACCESS_VIOLATION errors — a specific error code indicating memory access violations
• Performance degradation — general system slowdowns and instability

Initially, many US users believed the August 2026 Windows updates were responsible. However, Microsoft's investigation revealed a different culprit.

Root Cause: The inpoutx64.sys Driver

Microsoft's investigation pinpointed the inpoutx64.sys driver as the root cause of these issues.

What is inpoutx64.sys?

• A driver used by peripherals with built-in RGB lighting features
• Installed by various gaming keyboards, mice, and internal components with RGB lighting
• Found in systems where drivers or code components have file names similar to inpoutx64
• When present, it triggered crashes when launching certain games

Microsoft's Permanent Fix

Microsoft has resolved the issue by implementing a block that prevents the inpoutx64 driver from loading on affected devices.

Key details about the fix:

• Targets specific devices — only affects devices with the inpoutx64 driver enabled and the game ARC Raiders installed
• Disables the driver — prevents inpoutx64.sys from loading
• Displays a message — users see a message window with information about the disablement
• Normal game launch — following the message, games launch as normal
• Requires restart — a system restart is needed to apply the fix

How to Apply the Fix

For most US users, the fix will apply automatically through Windows Update. Here's what to expect:

For Consumer Devices:

1. The fix propagates automatically to Windows consumer devices
2. No manual action is required
3. A system restart is needed to apply the fix
4. The fix may take up to 24 hours to reach all devices

For Business Devices (Not Managed by IT):

1. The fix propagates to business devices that aren't managed by IT departments
2. A system restart is required
3. IT-managed devices will need manual intervention (see workaround below)

Enterprise Workaround for IT Administrators

Microsoft has provided a temporary workaround for enterprise-managed devices where the fix will not propagate automatically. US IT administrators should follow these steps:

Steps to Disable the inpoutx64 Driver:

1. Open the Windows Registry — open the Start menu and type "regedit". Select the Registry Editor from the results.
2. Navigate to the key — go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\inpoutx64. You can do this using the folders on the left side or by typing the path into the address bar.
3. Modify the Start value — on the right side, find the registry value named Start. Double-click this key and enter the number "4" under the field titled Value data.
4. Close the Registry Editor and restart your computer.

Why This Matters for US Users and Businesses

This Windows 11 fix is particularly important for US users and businesses:

• Widespread adoption — Windows 11 is used by millions of US consumers and businesses
• Gaming market — the US is one of the largest gaming markets globally, with millions of gamers affected
• Remote work — many US employees use Windows 11 for work, and system crashes disrupt productivity
• Enterprise environments — US businesses with IT-managed devices need the registry workaround
• RGB peripheral popularity — RGB gaming peripherals are extremely popular in the US market

Future Updates: September 2026 Security Updates

Microsoft has confirmed that the driver block will be included in the September 2026 Windows security updates and future releases. This means:

• Permanent fix — the driver block will be included in all future Windows updates
• No regression — the fix will prevent the issue from recurring
• Broader protection — all Windows 11 users will benefit from the permanent fix

Microsoft has a history of addressing gaming stability issues caused by Windows updates. Recent examples include:

• Removing upgrade blocks for Star Wars Outlaws, Assassin's Creed, Avatar: Frontiers of Pandora, and Asphalt 8: Airborne
• Fixing a bug in the Auto HDR Windows feature that was breaking some games on Windows 11 24H2 devices (January 2025)
