Microsoft says some users can’t open the Teams desktop client

Microsoft is addressing an issue (TM1466820) causing delays or preventing some users from accessing the Microsoft Teams desktop client on Windows systems, acknowledged on Thursday at 16:45 EDT. Affected users may experience loading failures or delays of up to two minutes and are advised to use the web or mobile versions of Teams as a temporary workaround.

Microsoft Teams, Outlook fail to launch on ARM-based Windows PCs

Microsoft is addressing an issue affecting users of Microsoft Teams and the new Outlook on ARM-based Windows devices, specifically the Surface Laptop 7 and Surface Pro 11, following updates released since the August 2026 Patch Tuesday. Users may experience crashes and launch failures after installing security updates from August 11, 2026, particularly update KB5121003. This issue primarily affects newly set up or freshly imaged PCs that lack the latest Microsoft Store updates, while classic Outlook, Word, Excel, and other applications remain unaffected. Microsoft recommends updating the Auto Super Resolution Package as a temporary workaround. A permanent fix is being developed and will be included in a future Windows update. Additionally, Microsoft has acknowledged other issues stemming from the August updates, including problems with printing and PDF exports in certain applications, and has been rolling out fixes for system crashes and gaming problems linked to peripherals with built-in RGB lighting. Customers are also advised to disregard alerts about Microsoft Defender Antivirus being disabled after the latest updates.

Microsoft rolls out fix for Windows 11 crashes, gaming issues

Microsoft has begun rolling out a permanent solution to a system stability and gaming performance issue on Windows 11 devices, which has caused crashes, game launch failures, and freezing, often with the "EXCEPTIONACCESSVIOLATION" error message. The problem was linked to updates from August 2026 and was identified as being related to peripherals with RGB lighting features that installed disruptive drivers. Specifically, the inpoutx64.sys driver was found to be responsible for these disruptions. Microsoft is deploying a fix that disables this driver on affected systems, starting from August 26, 2026. This driver block will also be included in the September 2026 Windows security updates. For enterprise-managed devices, a temporary workaround involves manually disabling the inpoutx64 driver via the Windows Registry. Microsoft has assured users that this action should not cause unintended behavior and can be reversed.

Microsoft rolls out fix for Windows 11 crashes, gaming issues

Microsoft has begun rolling out a permanent solution to a problem causing system crashes and gaming disruptions on Windows 11 devices, specifically related to game launch failures and freezing with "EXCEPTIONACCESSVIOLATION" errors. The issue affects various games, including ARC Raiders, MARVEL Tōkon: Fighting Souls, and The Finals, particularly on Windows 11 versions 24H2 and 25H2, and is linked to peripherals with built-in RGB lighting. The inpoutx64.sys driver has been identified as the cause of these complications. Microsoft is deploying a fix that disables this driver on affected devices, starting on August 26, 2026, and it may take up to 24 hours to reach all impacted devices. This driver block will also be included in the September 2026 Windows security updates. For enterprise-managed devices that do not automatically receive the fix, a temporary workaround involves disabling the inpoutx64 driver via the Windows Registry. Microsoft has stated that disabling this registry key should not lead to unintended behavior.

Microsoft is blocking the problem to fix Windows 11 KB5121003 restarts, crashes

Microsoft addressed printing issues and gaming-related complications linked to recent .NET Patch Tuesday updates. The problems were associated with RGB applications and the inpoutx64 system driver, which caused compatibility issues when certain games were launched. Microsoft has implemented a block to prevent the inpoutx64 driver from loading on affected devices, specifically targeting systems with the driver enabled and ARC Raiders installed. Users will receive a notification after the block is implemented, and the game should launch without further issues. The block is also being extended to systems running MARVEL Tōkon: Fighting Souls, while the issue with THE FINALS has been resolved. The resolution is being distributed automatically, and users need to restart their devices after the fix is applied. For enterprise-managed devices, IT administrators must manually apply the fix. Microsoft provided a temporary workaround by suggesting users disable the inpoutx64 driver through the Windows Registry. Users can change the Start value in the Registry Editor to 4 to disable the driver and may need to restart their devices for changes to take effect. Users are advised to back up the Registry before making modifications, and they can restore the driver by reverting the Start value back to its original setting.

Microsoft Now Says Your RGB Lighting Is Why Windows Keeps Crashing Your Games, and There Is a Registry Fix

Microsoft has identified RGB peripherals and components as the source of game crashes following the August 11 Patch Tuesday rollup for Windows 11. The issue stems from drivers or code components resembling inpoutx64, which are triggered when certain games are launched. Embark Studios linked the problem to update KB5121003, and Microsoft confirmed the connection to inpoutx64.sys, although the root cause involves changes to the Windows kernel driver. A temporary workaround involves editing the registry to disable the inpoutx64 driver, though this may affect RGB functionality. Affected games include ARC Raiders, MARVEL Tokon: Fighting Souls, and The Finals on Windows 11 versions 24H2 and 25H2, with symptoms like game freezing and unexpected closures. Rolling back the update is not recommended due to security vulnerabilities it addressed. The inpoutx64.sys driver has been included with various RGB and monitoring software, and Microsoft is investigating the issue further, asking users for feedback. No timeline for a permanent fix has been provided.

Microsoft: August updates break printing, PDF export in WPF apps

Microsoft has acknowledged a significant issue with the .NET Framework updates from August 2026, causing disruptions in printing and PDF export functionalities in certain applications, particularly those using the Windows Presentation Foundation (WPF) UI framework. After installing the update, some WPF applications may encounter a System.IO.FileFormatException when printing or generating PDF/XPS content with specific fonts, including Calibri. This issue affects various platforms, including Windows 10, Windows 11, and Windows Server editions from 2012 to 2025. Microsoft has provided a temporary workaround involving the Switch.MS.Internal.TtfDelta.DisableCmapAndSbitOverflowProtection AppContext switch, but cautions that it may expose systems to vulnerabilities. This situation is reminiscent of a similar incident in February 2021, where WPF applications and Visual Studio experienced crashes after Windows 10 cumulative updates. Additionally, on the same day, Microsoft offered a workaround for another issue caused by Windows 11 updates that led to crashes in certain games.
