在极少数情况下，我的程序在完成安装更新后会崩溃。它只是给了我一个：“ProgramName 已停止响应”错误并崩溃。我知道它一定是我的 Windows 更新安装的安装方法中的某个地方，但我无法弄清楚错误是什么或在哪里。
也许对 WUAPI.dll 有更多了解的人可以帮助我？
该程序是从 U 盘运行的，有时我可以通过将程序移动到桌面，然后从那里运行它来“解决”问题，但我想避免这样做。而且 AFAIK，我的代码实际上都没有访问 USB 棒或在更新安装过程中需要访问 USB 棒上的程序。当然，我可能只是缺少一些非常基本的东西..
#Region "Installation method"
Public Sub iInstallation()
Progression = "UpdateInstall"
iUpdateInstaller = TryCast(UpdateSession.CreateUpdateInstaller(), IUpdateInstaller)
iUpdateInstaller.Updates = NewUpdatesCollection
iInstallationJob = iUpdateInstaller.BeginInstall(New iUpdateInstaller_onProgressChanged(Me), New iUpdateInstaller_onCompleted(Me), New iUpdateInstaller_state(Me))
End Sub
Public Sub iInstallationComplete()
Try
Progression = "InstallComplete"
iDownloadJob.CleanUp()
iInstallationResult = iUpdateInstaller.EndInstall(iInstallationJob)

可能还值得注意的是，我在表格关闭和表格关闭事件期间有以下内容
Private Sub WUAPIProgress_FormClosing(sender As Object, e As FormClosingEventArgs) Handles MyBase.FormClosing
Try
Dim AutoUpdate = My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\", True)
AutoUpdate.SetValue("AUOptions", 4)
If Progression = "UpdateSearch" Or Progression = "SearchComplete" Then
iSearchJob.RequestAbort()
ElseIf Progression = "UpdateDownload" Or Progression = "UpdateComplete" Then
iDownloadJob.RequestAbort()
ElseIf Progression = "UpdateInstall" Or Progression = "InstallComplete" Then
iInstallationJob.RequestAbort()
End If
Catch err As Exception
MsgBox(err.Message)
End Try
End Sub
和：
Private Sub WUAPIProgress_FormClosed(sender As Object, e As FormClosedEventArgs) Handles MyBase.FormClosed
Me.Dispose()
End Sub
以为我有一些错误输出，不幸的是毕竟不是。它与别的东西有关。

我已经追踪了可能是主要问题。
该程序是从 U 盘运行的，如果该 U 盘在程序完成之前被移除，无论出于何种原因，它都会尝试到达应用程序启动的位置（U 盘），然后它会失败，和崩溃。
所以看来我必须让程序自行复制，然后从计算机上的某个位置运行。然而，奇怪的是，它并不总是一个问题。但是在运行 Windows 8.1 的虚拟机上，我几乎每次都观察到它。
我想我会多玩一点，因为我非常希望在程序启动并运行后能够移除 USB 记忆棒。让我困惑为什么它必须能够访问 .exe 才能完成向上？
