赢得11用PowerShell切换UAC

Question

I had disabled UAC with the command Set-ItemProperty -Path REGISTRY::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System -Name ConsentPromptBehaviorAdmin -Value 0

and reenabled UAC with Set- ItemProperty -Path Registry :: HKEY_LOCAL_MACHINE \ SOFTWORD \ MICROSOFT \ WINDOWS \ CurrentVersion \ Policies \ Policies \ System -Name ConsentPromptPromptBehaviorAdmin -Value -Value 1。

我的问题现在是UAC窗口看起来与切换UAC之前的外观不同。现在，它显示了用于输入管理员密码的字段。

知道如何将UAC设置为“正常”出现窗口？我无法提供UAC的屏幕截图，它总是显示一个空图像。

谢谢您的帮助！

Answer 1

一种方式：

REG ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v ConsentPromptBehaviorAdmin /t REG_DWORD /d 5 /f

另一种方式：

Set-ItemProperty -Path REGISTRY::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System -Name ConsentPromptBehaviorAdmin -Value 5

基本相同。这可以使用原始UAC窗口启用UAC，这意味着没有提示密码的提示。如果您想要该密码提示，将值从5更改为1。

function Set-UAC ([Parameter(Position = 0)][ValidateSet("AlwaysNotify", "NotifyChanges", "NotifyChangesNoDim","NeverNotify")][string]$Level = "NeverNotify") {
    $uacValues = @{
        "AlwaysNotify" = @{
            "PromptOnSecureDesktop"      = 1
            "EnableLUA"                  = 1
            "ConsentPromptBehaviorAdmin" = 2
        }

        $value = $values[$keyName]
        if ($keyExists) {
            Set-ItemProperty -Path $regPath  -Name $keyName -Value $value
