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.
