是否有人知道一个示例，或者可以提供一个示例，说明如何在Inno Setup的卸载过程开始时使用Windows内置的Restart Manager关闭explorer.exe，然后在删除文件后立即重新启动它？我有一些外壳程序项，即使取消注册后仍会分配它们，并且在explorer.exe关闭之前无法删除。
TIA！
这是一个如何做的例子：
{ Example how to use RestartManager and Offer Option to Delete App Data during Uninstall of Inno Setup }
{ Combined multiple open source ISS code found with some custom changes }
{ This could probably be cleaned up a bit, my goal was to get something to work. }
{ I also stripped it down a bit as I had multiple applications and data so hope }
{ everything removed without an issue, but I'm sure you can figure it out if so }
