ARM‑Based Windows PCs

Overview

Microsoft has acknowledged a known issue affecting ARM‑based Windows devices such as the Surface Laptop 7 and Surface Pro 11, where Microsoft Teams and the new Outlook fail to launch or crash unexpectedly after installing updates released since the August 2026 Patch Tuesday.

Impacted Systems

• ARM‑based devices: Surface Laptop 7, Surface Pro 11.
• Affected OS versions: Windows 11 24H2 or later.
• Applications impacted: Teams and New Outlook.
• Applications not affected: Classic Outlook, Word, Excel, and other Office apps remain unaffected.

Root Cause & Workaround

Microsoft has not yet disclosed the root cause but provided a temporary workaround:

• Update Auto Super Resolution Package:
  • Open Microsoft Store → Downloads → Check for updates.
  • Install Auto Super Resolution Package version 1.0.19.0 or later.
• This package, designed for Copilot+ PCs, uses AI to enhance gaming visuals but currently serves as a fix for Teams and Outlook launch failures.

Broader Context

This issue is part of a series of August 2026 update problems:

• Printing and PDF export failures caused by .NET Framework updates.
• RGB peripheral crashes leading to EXCEPTION_ACCESS_VIOLATION errors.
• Defender false alerts incorrectly warning users that antivirus protection was disabled.

Defensive Guidance

Users and IT admins should:

• Apply Microsoft Store updates immediately to mitigate the issue.
• Monitor Windows release health dashboard for official fixes.
• Delay non‑critical updates on ARM devices until stability patches are confirmed.
• Enable logging to capture crash data for troubleshooting.

Expert in the Cloud Insight

This incident highlights the fragility of update cycles on ARM‑based PCs, where compatibility issues can ripple across productivity apps. The lesson is clear: enterprise IT teams must validate updates in controlled environments before broad deployment, especially on newer architectures like ARM.
