**Major Issue Hits Microsoft Teams and Outlook Users on ARM-Based Windows PCs**
A significant problem has emerged for users of Microsoft Teams and New Outlook on ARM-based Windows devices, including popular models like the Surface Laptop 7 and Surface Pro 11. Since installing updates released since August’s Patch Tuesday, many users have reported that these applications fail to launch or close unexpectedly.
The issue affects only ARM-based Windows devices running Windows 11 24H2 or later, specifically impacting those who haven’t installed Microsoft Store updates yet. This means that users of other types of Windows PCs are not affected by this problem. According to Microsoft, classic Outlook, Word, Excel, and other applications remain unaffected.
The cause of the issue remains unknown, but Microsoft has identified a temporary workaround for affected customers. Users must update the Auto Super Resolution Package, which enables Copilot+ PCs to use AI to enhance gameplay. To do this, users need to open the Microsoft Store, go to Downloads > Check for updates, and install version 1.0.19.0 or later of the package.
This is not an isolated problem – it’s part of a series of known issues caused by Windows updates released in August. In recent days, Microsoft has confirmed that August .NET Framework updates can cause printing and PDF export problems in some applications, and has rolled out fixes for system crashes and gaming issues triggered by peripherals with built-in RGB lighting on Windows 11 devices.
The fact that multiple issues have emerged from recent Windows updates raises concerns about the quality control process. It’s essential for users to stay informed about potential problems caused by software updates and take necessary steps to mitigate them.
As a user, it’s crucial to be aware of these issues and take proactive measures to minimize disruptions. Updating the Auto Super Resolution Package is a straightforward step that can help resolve this specific problem. In addition, users should regularly check for Microsoft Store updates and apply any available patches to stay protected against known vulnerabilities. By being informed and taking preventive actions, you can ensure smoother operation of your applications and avoid potential headaches caused by software issues.
