Microsoft confirms Windows 11 upgrade for faster boot and 8GB RAM PCs, but shares no numbers

Microsoft announced at the IFA 2026 conference that Windows 11 will boot faster and improve performance on PCs with 8GB of RAM. The upcoming major update will enhance features like Windows Hello and include a movable taskbar, a resizable Start menu, and the option to remove Bing from Windows Search. The September 2026 Patch Tuesday update is expected to roll out these improvements. Mark Linton, Corporate Vice President of Windows & Devices at Microsoft, emphasized the company's goal of optimizing Windows 11 for 8GB RAM PCs due to rising memory costs. While 16GB of RAM has been historically recommended for optimal performance, Microsoft's focus on improving efficiency for 8GB systems aims to make technology more accessible.

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 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.

Windows 11’s August update broke Teams and Outlook on Arm PCs

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 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 is finally making it easier to mute Teams without hiding from your boss

Microsoft Teams will introduce a feature allowing users to temporarily pause notifications for a designated period, aimed at reducing notification overload and enhancing focus. The rollout is expected to start this month, with full availability by early October, and will be accessible through the profile menu in the application. This feature responds to user feedback for better notification management and differs from existing mute functions and the Do Not Disturb mode by allowing users to maintain their current status. There are questions about whether the pause feature will sync across devices or operate on a per-instance basis.

Windows 11 is getting faster, but its apps aren’t keeping up

Microsoft is enhancing Windows 11 by rolling out new context menus and refreshing the AutoPlay dialog box. Discussions are ongoing about branding the next major update as Windows 12, but improving the quality of applications is crucial for the overall user experience. Microsoft is working on enhancing its suite of applications, with developer Rudy Huyn assembling a team focused on improving Windows applications. Despite previous rebuilds, core issues with applications like Microsoft Teams persist, and there are concerns about whether the team will focus on native applications or continue to rely on sluggish web apps. Additionally, flagship applications like Photos and OneDrive may not be addressed by Huyn's team, potentially impacting user experience if Teams remains slow. Microsoft 365 is currently available at a discount when bundled with NordVPN.

A faster OS and UI fixes won’t save Windows 11 if Microsoft’s apps remain laggy web wrappers

Microsoft is testing new context menus and updating the AutoPlay dialog box in Windows 11. The Windows K2 initiative is prompting discussions about a potential Windows 12 update. Concerns remain about the performance of key applications like Microsoft Teams, which has been criticized for slow loading times. The upcoming Windows 11 update will include a refreshed Start menu, Taskbar enhancements, and quality fixes. A study by Signal65 found that the Snapdragon X2 Elite Extreme outperforms Intel and AMD chips. Rudy Huyn is leading a team to improve Windows applications, but it is uncertain how many apps will benefit from these efforts. Many major applications operate independently from Huyn's team, raising concerns about user experience. Microsoft 365 is currently available at a discount when bundled with NordVPN.

Windows 11 KB5121003 update breaks Teams and Outlook on ARM devices

Following the KB5121003 Patch Tuesday update, users on ARM64 devices like Surface Laptop 7 and Surface Pro 11 are facing startup failures with Microsoft Teams and New Outlook, while traditional Win32 applications remain unaffected. Reverting to the previous update restores functionality, but recovery options have not resolved the issue. The root cause appears to be broken AppModel Runtime package states, leading to dependency issues and 0x80073CFC errors. This problem is similar to one caused by update KB5094126 earlier this year. Creating new Windows profiles offers only temporary relief, and administrators are advised to pause the deployment of KB5121003 on ARM devices until the issue is addressed.
