Microsoft’s latest Windows update breaks cursors, wallpaper, and more – what to do if you’re affected

Windows 11 users who installed the September preview update (KB5120998) are experiencing a bug that alters or erases personalized mouse cursor settings, resulting in cursors that may be too large, too small, or invisible. Microsoft has acknowledged this issue, describing it as causing "appearance regressions and intermittent animation changes." High-DPI cursors have been replaced with larger, white cursors, and attempts to revert to previous settings have failed. Additionally, users have reported issues with wallpapers reverting to a black screen and blurry fonts, although Microsoft has not formally acknowledged the font issue. Users can uninstall the update by navigating to Settings, selecting Windows Update, clicking on Update History, and finding the option to uninstall the update labeled 2026-08 Preview Update (KB5120998). Microsoft is investigating the cursor problem and plans to provide updates by September 8.

‘Force Restart’—Microsoft Changes Windows Update Next Month

Microsoft will implement changes to Windows PC updates next month, requiring mandatory restarts for specific security component fixes in September and October. The September update will necessitate a "force restart," while the October update will follow the regular quarterly routine. These changes primarily affect managed PCs, and IT administrators are advised to inform users. Additionally, users are cautioned about the Windows 11 update KB5120998 due to issues like broken cursor styling and reset wallpaper settings, with some users successfully resolving problems by uninstalling the update. Windows 11 users are also experiencing a DISM error, 0x800f0915, when repairing the system image post-update, although reports of this issue are low.

Why does Windows constantly need to update?

Windows updates are released frequently to enhance performance, improve compatibility, fix bugs, and distribute critical security patches. Microsoft issues security updates every second Tuesday of the month, known as Patch Tuesday, which are cumulative, meaning the latest updates include all previous fixes. The Cybersecurity and Infrastructure Security Agency (CISA) issues warnings about vulnerabilities, and Microsoft maintains a security portal for documentation of these issues. Users on unsupported versions, like Windows 10 without Extended Security Updates (ESU), are at increased risk. In addition to security updates, Windows receives an annual feature update and occasional optional non-security updates that introduce new features and enhancements. An example is the Windows 11 February 2026 preview update, which added new features and improvements.

Why Does Windows Constantly Need To Update?

Windows updates are issued regularly, primarily for performance enhancement and security reinforcement. They address bugs, improve compatibility, and distribute security patches to mitigate vulnerabilities. Security vulnerabilities are frequently discovered, with alerts issued by the Cybersecurity and Infrastructure Security Agency (CISA) and documented in the Common Vulnerabilities and Exposures (CVE) program. Microsoft releases security fixes on Patch Tuesday, the second Tuesday of each month, and all updates are cumulative. Users of unsupported software versions, such as Windows 10, face increased security risks. Major feature updates occur annually, with optional non-security updates released periodically. For example, the Windows 11 February 2026 preview update introduced new features, although these are not part of the stable channel.

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.

Microsoft shares workaround after Windows KB5120708, KB5120705, KB5120710 break printing

Microsoft released its monthly Patch Tuesday security updates, which included dynamic updates and new .NET Framework versions. Users of Windows 11, Windows 10, and Windows Server are experiencing printing issues after installing the August 2026 .NET Framework cumulative updates, particularly with Windows Presentation Foundation (WPF) applications that fail during printing tasks or when generating PDF or XPS documents. The problems are linked to specific fonts, notably Calibri, and may result in a System.IO.FileFormatException. Microsoft has provided a temporary workaround involving an AppContext switch, but enabling this switch disables certain security protections from the August 2026 update, potentially exposing applications to vulnerabilities. No permanent fix or timeline for one has been provided.

Microsoft shares temporary fix for Windows 11 gaming issues

Microsoft has acknowledged gaming issues related to Windows 11 updates released on August 11, 2026, affecting games like ARC Raiders, MARVEL Tōkon: Fighting Souls, and The Finals. Problems reported include game crashes, failures to launch, freezes, and unexpected system restarts, particularly on Windows 11 versions 24H2 and 25H2. Microsoft identified a link between these issues and drivers or components associated with RGB lighting devices, specifically the inpoutx64.sys driver. A temporary workaround involves disabling the inpoutx64 driver through the Windows Registry, with caution advised regarding potential unintended consequences. Users are encouraged to report issues via the Feedback Hub app as Microsoft investigates further.

Tested: Windows 11 has fully removed the legacy tool abused by cybercriminals for malware and ransomware, called WMIC

Windows 11 will remove the Windows Management Instrumentation Command-line (WMIC) tool in the upcoming September 2026 Update, marking its complete elimination after being deprecated in earlier versions. Testing of early builds shows that WMIC is no longer accessible, with attempts to use it resulting in a "command not recognized" error. Previously, WMIC was available as an optional feature, but it will no longer be included or reactivatable in the new update. Microsoft stated that this removal aims to improve the security and reliability of Windows, as WMIC has been exploited by cybercriminals for attacks. The September 2026 Update will also introduce other enhancements, including the ability to disable Bing in Windows Search and improvements in app speed.
