超链接（hyperlink）第一次启动超级慢的问题

  超链接（hyperlink）第一次启动会超级慢，有多慢，用秒表测了一下，五分钟。

但第一次启动，进入对话框以后，后面都快了。为什么会这样，上次查了一下，仅有一个贴子说了一下。
https://www.cadforum.cz/en/hyper ... %20on%20the%20first,before%20the%20dialog%20appears%2C%20AutoCAD%20appears%20to%20%22hang%22.

When you invoke the HYPERLINK command (Ctrl+K) for the first time in a session, its response time may be very slow - you might wait minutes before the dialog appears, AutoCAD appears to "hang".
This command reads in (scans and caches) all files in the Documents folder, including its subfolders and any shortcuts (links) placed in it.

In case of large folders, network folders (mapped) and invalid shortcuts (non-existent), this scanning may take minutes.

You can make the response faster by cleaning the Documents folder of useless and obsolete shortcuts. AutoCAD scans the folder Documents („My Documents“), so as it is defined in the Registry key:

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal

this key usually points to:

%USERPROFILE%\Documents

它说，第一次启动超链接（hyperlink）超级慢，是因为，它要扫描 “文档” 这个文件夹，包括它所有的文件和文件夹，如果文件夹很大，就会花费很多时间。

又说，它扫描的文件在注册表中在这个键下：
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal
键值：
%USERPROFILE%\Documents

尝试了一下，问题没有解决，还是搞不清CAD第一次启动超链接的时候到底在干什么，为什么会那么多时间，到底要怎么做才能快起来。
