🚀 使用方法

1. 复制代码到记事本
2. 保存为 CleanSystem.ps1
3. 右键文件 -> 以管理员身份运行
4. 在PowerShell中执行

💡 安全提醒

• ✅ 该脚本不会删除个人文件（文档、图片等）
• ✅ 清理范围经过测试，不会影响系统稳定性
• ⚠️ 首次运行建议先查看代码再执行
• ⏸ 想暂停按 Ctrl+C

🔧 进阶定制

如果你懂点PowerShell,可以：

# 添加自定义清理路径
Clear-JunkFiles "D:\Temp\*" "D盘临时文件"
# 修改保留天数（可选）
Get-ChildItem $path -Recurse | Where-Object {$_.LastWriteTime -lt (Get-Date).AddDays(-7)} | Remove-Item

这个脚本能帮你释放10~50GB空间（视使用情况），而且比手动清理彻底得多，试试看，你会发现系统跑得更顺畅了！
