背景
这阵子想把「微软电脑管家」（Microsoft PC Manager）从机器上清掉。常规卸载走完流程，任务栏图标没了，但重启后它又"自己回来了"。期间还踩了两个坑：PowerShell 执行策略阻止脚本运行 、中文输出导致脚本乱码报语法错。下面是完整解决方案和一键脚本，亲测可复现。
先说结论
- 正确流程是：结束后台进程 → 卸载（含 Store/传统安装）→ 清残留文件 → 清理启动项/计划任务 →（可选）关闭自动回装来源。
- 一键脚本能把整套动作做完；考虑到编码问题，我给出英文输出版脚本，避免中文乱码导致的语法错误。
- 临时绕过 PowerShell 执行策略再运行脚本，不用永久降低安全性。
快速上手（一步到位）
-
把下面的脚本内容保存为
Remove-PCManager.ps1（建议用 VS Code 保存为 UTF-8；英文版脚本不要求 BOM）。 -
以管理员 打开 PowerShell，先执行（只对当前窗口生效）：
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass -
运行脚本：
.\Remove-PCManager.ps1 -
完成后重启一次电脑。
一键卸载脚本（英文输出版，避免中文编码坑）
<#
Remove-PCManager.ps1
What it does:
1) Kill PC Manager related processes/services
2) Uninstall via winget / registry (MSI/EXE) / Microsoft Store (Appx)
3) Clean leftover files, shortcuts, startup entries, scheduled tasks
4) (Optional) Set policies to reduce auto-reinstall
Usage:
- Run PowerShell as Administrator
- (Temporary) bypass policy for this session:
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
- Execute:
.\Remove-PCManager.ps1

-
脚本报"在此系统上禁止运行脚本"
解决：临时放行当前会话即可（安全、用完恢复）
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass-
中文乱码导致脚本语法错误
如果你用了中文输出版脚本，请用 VS Code「保存为编码 → UTF-8 with BOM」。
避坑法：直接用上面英文输出版，不依赖 BOM 也不会乱码。
-
卸载后又装回来了
多半来自 Microsoft Store 自动更新或"消费者体验"推送。把脚本最后一行的：
Optional-Block-Reinstall -EnableBlock:$false改成：
*
Optional-Block-Reinstall -EnableBlock:$true运行一次，再重启。
-
找不到 winget
没关系，脚本会自动走注册表卸载 + Appx 移除，不影响结果。
需要恢复设置时怎么做？
若你启用了"防回装"（脚本会写入两条策略），想恢复默认：
- 打开 Microsoft Store ，重新开启 自动更新应用；
- 或删除这两个策略键值（需要管理员）：
HKLM\SOFTWARE\Policies\Microsoft\WindowsStore\AutoDownloadHKLM\SOFTWARE\Policies\Microsoft\Windows\CloudContent\DisableConsumerFeatures
小结
这次折腾的关键经验有三点：
- 卸载要成体系，别只点"卸载"。
- PowerShell 脚本先临时绕过执行策略，跑完就关窗口。
- 避免中文编码坑------脚本用英文输出最省心，或者 UTF-8 with BOM 保存。
