description

Create safe, privacy-preserving Windows 11 C-drive cleanup, storage migration, cache relocation, package-manager policy, and maintenance plans. Use when the user asks about Win11 C盘清理, disk bloat, AppData, Windows Installer, WinSxS, WindowsApps/UWP, winget, Scoop, dev caches, browser profiles, NVIDIA shader cache, package caches, or recurring cleanup automation across one or many Windows 11 devices.

Win11 Storage Governance

Workflow

Clarify scope: template-only, audit-only, or execute-on-this-device. Default to template-only unless the user explicitly asks to inspect or change the local machine.
Load references/safety-model.md before recommending deletion, junctions, package-manager changes, or environment-variable changes.
Load references/runbook.md when producing a full plan, checklist, migration guide, or remediation sequence.
Load references/device-profile-template.md when the user wants a reusable template for another Windows 11 device.
Produce a staged plan: observe, classify, clean, migrate, automate, verify, rollback.

Privacy Rules

Do not read %USERPROFILE%, AppData, registry hives, package-manager state, shell history, environment variables, or local project folders unless the user explicitly requests a local audit/execution.
Do not copy personal paths, usernames, machine names, package lists, logs, or environment values into reusable templates.
When examples need paths, use neutral placeholders such as <User>, <DownloadDrive>, <DevCacheRoot>, and <ModelDrive>.
Treat this repository's example device layout as a model pattern, not as a user's private configuration.

Safety Gates

Never recommend manually deleting or junctioning C:\Windows\Installer, C:\Windows\WinSxS, C:\Program Files\WindowsApps, the whole AppData, the whole user profile, or the whole ProgramData.
Prefer official tools for Windows Update, WinSxS, Store/UWP apps, Visual Studio, drivers, and MSI repair.
Use junctions only for clearly regenerable caches, with backup, testing, and rollback steps.
For chat apps, browsers, password stores, databases, and device-bound app state, separate cache from user data before suggesting cleanup.
For destructive commands, present a dry-run or staged quarantine approach unless the user explicitly asks to execute and the target is already classified.

Output Contract

For a cleanup or migration plan, include:

Risk classification: safe clean, official-tool clean, migrate/configure, investigate, do-not-touch.
Concrete paths using placeholders unless doing an explicit local audit.
Commands only where they are safe and scoped; otherwise give GUI/offical-tool instructions.
Verification steps and rollback steps.
A recurrence plan that uses allowlists and age thresholds instead of broad deletion.

For local execution, include:

What will be inspected before running commands.
What will be changed, quarantined, or left untouched.
A summary of actions taken and remaining risks.
