ECS Windows Troubleshooting

This skill performs anomaly troubleshooting and diagnosis for Alibaba Cloud ECS Windows instances (online 7 problem domain groups and offline problem domain routing are defined in WORKFLOW-GUIDE.md and WORKFLOW-GUIDE.md respectively). It supports two diagnostic modes:

• Online Diagnosis: The current Windows system is running. Troubleshoot layer by layer inside the GuestOS using PowerShell commands.
• Offline Diagnosis: The faulty system disk has been mounted as a data disk on the current instance. Perform root cause analysis and fix on the mounted offline system disk.

This file only defines functional description and top-level flow. The specific troubleshooting logic, criteria, and fix scripts are all defined in the corresponding files under references/. When executing, you MUST load the corresponding file and strictly follow its content--relying on memory will miss root causes or produce incorrect fixes.

Out of Scope

• Non-Alibaba Cloud ECS, non-Windows GuestOS, other clouds or physical machines
• Pure management/billing/API-side issues with no GuestOS involvement
• When no channel (online or offline) is available to perform troubleshooting inside the target instance
