【问题描述】：
我正在尝试编写一个脚本，该脚本将从用户 HKLM 中删除旧队列（最终将通过挂载 ntuser.dat 从 HKCU 中删除，但我还没有）。
我遇到的问题是我只遍历 SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider\ 下的一个 sid，我收到以下错误消息：
“else”一词未被识别为 cmdlet、函数、脚本文件或可运行程序的名称。检查名称的拼写，或者如果包含路径，请验证路径是否正确 等然后再试一次。
以前有人遇到过这个问题吗？

你有正确数量的花括号，但一个在错误的位置。很难从快速回顾中分辨出哪一个，我会稍微整理一下您的缩进，并确保它们都与您期望的位置相匹配。这是问题的一个线索是 ISE 以不同的颜色突出显示“else”，并且错误基本上是说“有一个我没想到的 else 语句”。
