通过PowerShell卸载应用程序

我已经为此工作了几天,无论我如何运行和使用它,它似乎都会通过PowerShell卸载程序并返回成功代码:

__GENUS          : 2
__CLASS          : __PARAMETERS
__SUPERCLASS     :
__DYNASTY        : __PARAMETERS
__RELPATH        :
__PROPERTY_COUNT : 1
__DERIVATION     : {}
__SERVER         :
__NAMESPACE      :
__PATH           :
ReturnValue      : 0
PSComputerName   :

这种情况发生在各种众所周知的难以删除的软件上,如McAfee。

使用的命令是:

 Get-WmiObject -Class win32_product -Filter "Name like '%McAfee%'" | ForEach-Object {$_.Uninstall()}

我在这里尝试了各种脚本、解决方案以及它们的变体(如下面)。

$uninstall32 = gci "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | foreach { gp $_.PSPath } | ? { $_ -match "Yahoo Messenger" } | select UninstallString

$uninstall64 = gci "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" | foreach { gp $_.PSPath } | ? { $_ -match "Yahoo Messenger" } | select UninstallString

if ($uninstall64) {
    $uninstall64 = $uninstall64.UninstallString -Replace "msiexec.exe","" -Replace "/I","" -Replace "/X",""
    $uninstall64 = $uninstall64.Trim()
    Write "Uninstalling (x64)..."
    start-process "msiexec.exe" -arg "/X $uninstall64 /qb" -Wait
    }
if ($uninstall32) {
    $uninstall32 = $uninstall32.UninstallString -Replace "msiexec.exe","" -Replace "/I","" -Replace "/X",""
    $uninstall32 = $uninstall32.Trim()
    Write "Uninstalling (x32)..."
    start-process "msiexec.exe" -arg "/X $uninstall32 /qb" -Wait}

即使是像Yahoo Messenger这样简单的命令,当以管理员身份从Powershell窗口运行时,该命令也无法卸载应用程序,但返回成功代码和/或WMI应用程序列表中不再存在。
