And*_*dry 41 windows powershell
我在更改Windows Server 2008+操作系统中的执行策略时遇到问题.这是我第一次尝试运行我需要资源完全访问权限的脚本,并在升级模式下启动Powershell后尝试以下操作:
Set-ExecutionPolicy Unrestricted

但我明白了:
Set-ExecutionPolicy : Windows PowerShell updated your execution policy
successfully, but the setting is overridden by a policy defined at a more
specific scope. Due to the override, your shell will retain its current
effective execution policy of RemoteSigned. Type "Get-ExecutionPolicy -List"
to view your execution policy settings. For more information please see
"Get-Help Set-ExecutionPolicy".

虽然我是管理员,但我无法更改执行政策.该怎么办?

错误消息表示您尝试定义Set-ExecutionPolicy
的设置被另一个范围中的设置覆盖.用Get-ExecutionPolicy -List
看哪个范围有哪些设置.

正如您所看到的,尽管存在错误,但两个设置都已定义,但更具体的范围(Process
)中的设置仍然优先,阻止或允许脚本执行.
由于默认范围是LocalMachine
错误可能是由CurrentUser
或Process
范围中的设置引起的.但是,更常见的原因是脚本执行是通过组策略(本地或域)配置的.
本地管理员可以通过gpedit.msc
(本地组策略编辑器)修改本地组策略,如本答案中所述.
域组策略不能被本地设置/策略取代,必须由域管理员通过gpmc.msc
域控制器上的(组策略管理)进行更改.
对于本地和域策略,可以将设置定义为计算机设置:
Computer Configuration
`-Administrative Templates
`-Windows Components
`-Windows PowerShell -> Turn on Script Execution

或作为用户设置:
User Configuration
`-Administrative Templates
`-Windows Components
`-Windows PowerShell -> Turn on Script Execution

前者适用于计算机对象,后者适用于用户对象.对于本地策略,用户和计算机策略之间没有显着差异,因为用户策略会自动应用于计算机上的所有用户.
策略可以具有三种状态之一(如果计算可用于单独启用状态的3种设置,则为五种状态):
Set-ExecutionPolicy AllSigned
).Set-ExecutionPolicy RemoteSigned
).Set-ExecutionPolicy Unrestricted
).Set-ExecutionPolicy Restricted
)相同.Set-ExecutionPolicy
仅当本地和域策略设置为" 未配置"(Undefined
范围MachinePolicy
和中的执行策略UserPolicy
)时,所做的更改才会生效.

问题是Windows不允许所有脚本在Unrestricted
模式下执行.实际上,无论您的用户执行策略(即使是管理员),Local Group Policy
都将优先考虑.
默认情况下,本地组脚本执行策略是不允许执行脚本的策略.我们需要改变它!
我们通过Local Group Policy Editor
在Windows搜索栏中搜索"组策略"来实现此目的.或者这样做:
Win + r
并键入命令打开管理控制台mmc
.File -> Add Remove Snap In...
.Group Policy Object Editor
并添加它.然后在左窗格中可以展开组编辑器.展开它并导航到Computer Configuration -> Administrative Templates -> Windows Components
.
然后到Windows PowerShell
.
所以选择Turn on Script Execution
.更改配置Enabled
,并指定Allow all scripts
在Execution Policy
.
通过按下Ok
并关闭管理控制台进行确认.

现在可以安装修补程序:

即使@Ansgar Wiechers 的回答不起作用.. 那么您的 MachinePolicy 范围可能会出现问题。因此,该问题的一种解决方法是.. 编辑 ExecutionPolicy 键的注册表值在
HKEY_LOCAL_MACHINE -> 软件 -> 策略 -> Microsoft -> Windows -> Powershell
在尝试了这么多解决方案后,它对我来说执行 ps 脚本很有用。
如果域控制器通过组策略设置了PowerShell ExecutionPolicy,则每次启动后必须在注册表中将ExecutionPolicy重置为“绕过”。我创建了一对启动脚本来自动化该过程。下面,我描述我的过程。
创建一个名为%USERPROFILE%\ Documents \ StartupScripts的文件夹,然后使用以下代码在其中放置一个名为ExecutionPolicy.ps1的PowerShell脚本:
Push-Location
Set-Location HKLM:\Software\Policies\Microsoft\Windows\PowerShell
Set-ItemProperty . ExecutionPolicy "Bypass"
Pop-Location

然后创建一个名为%USERPROFILE%\ AppData \ Roaming \ Microsoft \ Windows \ Start Menu \ Programs \ Startup \ Startup.cmd的文件,并将以下代码放入其中:
PowerShell -Version 3.0 -Command "Set-ExecutionPolicy Unrestricted" >> "%TEMP%\StartupLog.txt" 2>&1
PowerShell -Version 3.0 "%USERPROFILE%\Documents\StartupScripts\ExecutionPolicy.ps1" >> "%TEMP%\StartupLog.txt" 2>&1

该脚本将在每次登录开始时运行。
将以下内容添加到名为的文件中psa.cmd
,并将其放入包含您的 PATH 的文件夹中:
POWERSHELL -Command "$enccmd=[Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes((Get-Content '%1' | Out-String)));POWERSHELL -EncodedCommand $enccmd"

现在您可以运行任何 powershell 脚本,如下所示:
