Microsoft has acknowledged issues with the August security update KB5121003 for Windows 11, affecting versions 24H2 and 25H2. Users reported problems such as game freezing, unexpected closures, and system restarts after installing the update. The issues are linked to drivers and software for specific RGB-enabled peripherals or components, particularly involving the inpoutx64.sys driver. Games mentioned include ARC Raiders, MARVEL Tōkon: Fighting Souls, and THE FINALS. Embark Studios has released a support guide suggesting users stop and remove the inpoutx64.sys service as a temporary workaround. Microsoft is investigating the issue but has not provided a definitive fix or patch timeline.

Windows 11 will reintroduce the “Preview anyway” button for downloaded files in File Explorer, enhancing functionality and convenience. This update is expected to roll out in the coming weeks. The Preview pane in File Explorer stopped displaying previews for downloaded files on October 14, 2025, due to a security measure implemented by Microsoft to protect users from potential threats associated with previewing unsafe files. Users received warnings when attempting to preview downloaded files, advising them to trust the source. The restriction affects files marked with the Mark of the Web, including various downloads from browsers and email attachments. Previously, users could unblock files manually or through PowerShell scripts. The new “Preview anyway” button will allow users to override the warning for trusted files while still receiving a cautionary message.

WMIC, a utility for IT administrators introduced in Windows XP in 2001, will be removed from Windows 11 after August 2026.

A recent update has been released, addressing security vulnerabilities and improving system functionality. Key improvements include a fix for the Backup feature, resolving an "invalid credentials" error that caused automatic backups to fail when using Server Message Block (SMB).

This update addresses outdated Secure Boot certificates for Windows 11 and Windows 10 users. The update, identified as KB5120249, is under 1 GB and is available only to PCs enrolled in the Extended Security Updates (ESU) program, which ensures Windows 10 PCs receive security updates until at least October 2027. Non-enrolled PCs lost security update support in October 2025.
