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 is analyzing service logs and telemetry data to identify the root cause and has contacted some affected users for more information. Additionally, there is a separate issue (TM1466659) affecting Mac users, preventing them from joining Teams calls and meetings, confirmed on Sunday at 08:32 EDT. Microsoft is reassessing the cause of this disruption. Earlier this year, Microsoft resolved an issue blocking some Teams Free users from chats and calls. The company also confirmed a bug causing crashes and launch failures for Teams and New Outlook users after recent Windows security updates. Furthermore, there is an ongoing Exchange Online issue affecting multiple mailboxes, resulting in "Server busy" errors and delays in email communications with external domains.

Microsoft has identified an issue affecting Microsoft Teams and the new Outlook for Windows on Arm-based devices, such as the Surface Pro 11 and Surface Laptop 7, following the installation of Windows security updates released on or after August 11, 2026, specifically the KB5121003 update. The affected Windows 11 versions include 24H2, 25H2, and 26H1, causing these applications to fail to launch or close unexpectedly, while classic applications like Outlook, Word, and Excel remain unaffected. The issue is more prevalent on new or freshly imaged PCs that have not received updates from the Microsoft Store. Microsoft is working on a solution to be included in a future Windows update. In the meantime, users can mitigate the issue by updating to the latest version of the Auto Super Resolution Package (version 1.0.19.0 or later) via the Microsoft Store.

Microsoft is expanding the memory integrity protection feature in Windows 11, starting in October. This enhancement aims to strengthen security at the kernel level against sophisticated attacks. Memory integrity protection operates in the background with minimal user configuration. It utilizes Virtualization-based Security (VBS) to create isolated virtual environments for added protection. The system can install security hotpatches without requiring a hard restart, beneficial for critical environments. Large organizations will automatically benefit from this enhancement, while devices with memory integrity disabled will not have it activated automatically. The rollout will enable VBS by default for users, who can choose to disable it but should do so with caution.

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.

Home Wi-Fi connects various devices and presents security risks, making firewalls important for network protection. A router firewall is built into the home router and protects all connected devices, while a software firewall operates on individual devices for additional security. Inbound traffic is data coming to a device, while outbound traffic is data leaving it; firewalls analyze this traffic to manage connections. Network security is critical as sensitive information is often accessed on devices used for leisure, and remote work increases data overlap. Firewalls can control network connections and filter unwanted traffic but cannot replace weak passwords or antivirus protection. To enhance home network security, users should secure router settings, keep routers updated, strengthen Wi-Fi access, check connected devices, and replace outdated routers. A comprehensive security strategy includes keeping software updated, using multifactor authentication, being cautious with links, and strengthening firewalls with antivirus protection. Protecting valuable data is essential, and understanding ransomware risks is crucial. The 3-2-1 backup strategy involves maintaining three copies of data on two different storage types, with one copy offsite. Regularly testing backups and knowing how to respond to ransomware incidents are also important.

Nvidia will stop releasing performance updates and new features for its Game Ready Drivers and Nvidia Studio Drivers on Windows 10. Users with GeForce graphics cards will only receive quarterly security updates from October 2026 until October 2029, after which no updates will be provided. Existing games will continue to work, but new bugs will not be addressed, and gamers will miss out on optimizations for new titles. This situation may lead many users to consider transitioning to Windows 11 for continued support and features.

Cybercriminals are targeting Android users with deceptive advertisements for malicious applications disguised as pornographic content on platforms like Facebook and Instagram. The National Cybercrime Threat Analytics Unit (NCTAU) has reported that these ads lead users to phishing traps or malware downloads that can compromise banking credentials. Malicious applications linked to this threat include “Night Play,” “Reloop,” “Kyss,” “Vimo,” “Rivo,” “Nexo,” and “Vixa.” The scam involves promoting these apps through enticing ads, redirecting users to websites offering pornographic content, and prompting them to download APK files directly from these sites, often using “.live” domains. The initial app may request users to download a second package disguised as an update, which can exploit permissions granted to the first app. This malware can gain extensive control over the device, potentially installing a VPN that routes internet traffic through attackers' servers. To protect against this threat, users should download apps only from trusted sources, avoid installing APK files from ads or suspicious links, refrain from granting Accessibility access to unknown apps, regularly review installed apps, keep Google Play Protect enabled, and monitor bank accounts for unusual activity. If a suspicious app cannot be uninstalled, users can try Safe Mode, remove special permissions, or perform a factory reset as a last resort.

Windows 10 will receive support until October 2027 under the Extended Security Updates (ESU) program, with approximately 30% of PCs still operating on this system. Nvidia will stop releasing Game Ready Drivers for Windows 10 in October 2026, and from November 2026, users will not receive game-related fixes or optimizations. Security updates will remain available until at least October 2029, but the lack of patches for new bugs may affect gaming experiences. HP reports that around 30% of PCs are still running Windows 10, and the company expects these users to transition to Windows 11 or invest in new hardware. Microsoft acknowledges that the growth of Windows 11 has slowed and is focusing on enhancing its features.

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.
