• [nitpick] The plaintext fence removes syntax highlighting. For better readability of mixed output and errors, consider using a more appropriate tag like console or bash.

```plaintext

• [nitpick] Using an HTML <strong> tag here creates inconsistency with the rest of the document. Consider reverting to standard markdown **对于小白…** and addressing the parser issue (e.g., by escaping the leading hyphen) for uniform formatting.

<strong>对于小白，我建议你永远不要动这个东西。</strong>如果一个教程说要修改`HKLM`项目，如可能，请试着寻找其他替代手段。
