Question

我使用NSIS创建了一个安装程序。现在我面临一个问题，比如我的应用程序可以创建一个计划任务，但是当我卸载它时，它不会删除/删除我从我的应用程序创建的任务，它们仍然可以在Schedule Tasks中看到。我每次都安排一个自动运行任务。

如何在卸载时从Schedule Tasks中删除自动运行任务？

最好的选择可能只是让你的应用程序这样做; ExecWait '"$instdir\myapp.exe" /uninstalltask'

您还可以使用nsExec plugin执行at.exe / schtasks.exe。

直接调用任务调度程序API很复杂，需要处理两个版本：

!include LogicLib.nsh
;V1:
!define CLSID_CTaskScheduler {148BD52A-A2AB-11CE-B11F-00AA00530503}
!define IID_ITaskScheduler {148BD527-A2AB-11CE-B11F-00AA00530503}
;V2:
!define CLSID_TaskScheduler {0F87369F-A4E5-4CFC-BD3E-73E6154572DD}
!define IID_ITaskService {2FABA4C7-4DA9-4013-9697-20CC3FD40F85}
