原来的问题：
目前：
regedit /e "X:\Users\Default\Desktop\1.reg" HKEY_CLASSES_ROOT\Imagine.PNG\shell\抓滚动
导出的注册表1.reg：
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Imagine.PNG\shell\抓滚动]
@="抓滚动"
[HKEY_CLASSES_ROOT\Imagine.PNG\shell\抓滚动\command]
@=hex(2):44,00,3a,00,5c,00,31,00,ff,7e,72,82,6f,8f,f6,4e,5c,00,1a,59,92,5a,53,\
4f,5c,00,93,62,fe,56,93,62,da,6e,a8,52,5c,00,93,62,da,6e,a8,52,46,00,53,00,\
43,00,61,00,70,00,74,00,75,00,72,00,65,00,39,00,37,00,5c,00,46,00,53,00,43,\

从这里看不到程序路径
—————————————————————————————————————————————
希望运行一个命令，导出的注册表中看到程序路径，形如：
Windows Registry Editor Version 5.00
