Powershell写入注册表的麻烦 [英] Trouble with Powershell writing to registry
问题描述
我正在编写一个脚本，它将修改Windows机器上的一些注册表设置。
我正在使用if来确定密钥是否/在写它们之前存在属性。它应该失败并写一个错误，如果它。这个块正在工作：
$ currentPath ='HKLM：\Software\Microsoft \ Windows \ CurrentVersion \POLicies\Ext'
$ pathTest = Test-Path $ currentPath
Write-Host -ForegroundColor Yellow'测试：'$ currentPath
If（$ pathTest -ne'True'）
{
New-Item -Path $ currentPath -Force | Out-Null
写主机-ForegroundColor Green'创建路径：'$ currentPath
}
否则{
Write-Host -ForegroundColor Red $ currentPath'已经存在。'
}
Write-Host -ForegroundColor黄色'禁用IE加载项性能通知（DisableAddonLoadTimePerformanceNotifications）：'
If（（Get-ItemProperty $ currentPath -Name'DisableAddonLoadTimePerformanceNotifications'-ea 0 '。DisableAddonLoadTimePerformanceNotifications'）
{
Write-Host -ForegroundColor Red'AdapableAddonLoadTimePerformanceNotifications已经存在'
}
Else {
New-ItemProperty -Path $ currentPath -Name DisableAddonLoadTimePerformanceNotifications -PropertyType DWord -Value'1'| Out-Null
写入主机-ForegroundColor绿色'DisableAddonLoadTimePerformanceNotifications创建并设置为1'
}
如果键/属性它给我这个输出存在：
测试：HKLM：\软件\微软\ Windows \ CurrentVersion \POLicies\Ext
HKLM：\ Software \ Microsoft \ Windows \ CurrentVersion \POLicies \ Exxt已经存在。
禁用IE加载项性能通知（DisableAddonLoadTimePerformanceNotifications）：
DisableAddonLoadTimePerformanceNotifications已存在
但是，此块不起作用：
$ currentPath ='HKLM：\Software \POLicies\Microsoft \Internet Explorer \ Main'
$ pathTest = Test-Path $ currentPath
Write-Host -ForegroundColor Yellow'测试：'$ currentPath
If（$ pathTest -ne'True'）
{
New-Item -Path $ currentPath -Force | Out-Null
写主机-ForegroundColor Green'创建路径：'$ currentPath
}
否则{
Write-Host -ForegroundColor Red $ currentPath'已经存在。'
}
If（（Get-ItemProperty $ currentPath -Name'EnableAutoUpgrade'-ea 0）。'EnableAutoUpgrade'）
{
Write-Host -ForegroundColor Red'EnableAutoUpgrade已经存在'
}
Else {
New-ItemProperty -Path $ currentPath -Name'EnableAutoUpgrade'-PropertyType DWord -Value'0'| Out-Null
写入主机-ForegroundColor绿色'EnableAutoUpgrade已创建并设置为0'
}
如果键/属性存在，则输出：
测试：HKLM：\软件\政策\微软\互联网资源管理器\主要
HKLM：\软件\政策\微软\ Internet Explorer \已经存在。
New-ItemProperty：该属性已存在。
在C：\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo：ResourceExists：（HKEY_LOCAL_MACH ... t Explorer \ Main：字符串）[New-ItemProperty]，IOException
+ FullyQualifiedErrorId：System.IO.IOException，Microsoft.PowerShell.Commands.NewItemPropertyCommand
创建EnableAutoUpgrade并设置为0
密钥/属性的输出不存在：
测试：HKLM：\ Software \POLicies\Microsoft \\ \\ Internet Explorer \ Main
创建路径：HKLM：\软件\POLicies\Microsoft \Internet Explorer \ Main
禁用IE自动升级（EnableAutoUpgrade）：
EnableAutoUpgrade created and设置为0
所以，它会创建属性没问题，但看不出它是否已经存在。我我看起来像是If在这个失败，但我无法弄清楚为什么。它和它上面的一样。在完整脚本中，我运行了总共14个注册表项。高于
`EnableAutoUpgrade`的所有工作都可以。 "EnableAutoUpgrade"下面的那些没有，并且失败并出现同样的错误。
$
这种情况发生在运行Win8.1和PowerShell v4的多台机器上。 />
这真是令人头疼的问题。任何帮助将不胜感激。
这一行很奇怪：
If（（Get-ItemProperty
currentPath -Name'EnableAutoUpgrade'-ea 0）。'EnableAutoUpgrade'）
尝试将其替换为：
如果 （（（Get-ItemProperty -Path
currentpath -Name EnableAutoUpgrade）.EnableAutoUpgrade）-eq 0）
它更好吗？
I'm writing a script that will modify some registry settings on Windows machines.
I'm using an If to determine if the key/property exist before writing them. It should fail and write an error if it does. This chunk is working:
$currentPath = 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Policies\Ext'
$pathTest = Test-Path $currentPath
Write-Host -ForegroundColor Yellow 'Testing for: ' $currentPath
If($pathTest -ne 'True')
{
New-Item -Path $currentPath -Force | Out-Null
Write-Host -ForegroundColor Green 'Created Path: '$currentPath
}
Else{
Write-Host -ForegroundColor Red $currentPath ' already exists.'
}
Write-Host -ForegroundColor Yellow 'Disabling IE Add-On Performance Notifications (DisableAddonLoadTimePerformanceNotifications):'
If((Get-ItemProperty $currentPath -Name 'DisableAddonLoadTimePerformanceNotifications' -ea 0).'DisableAddonLoadTimePerformanceNotifications')
{
Write-Host -ForegroundColor Red 'DisableAddonLoadTimePerformanceNotifications already exists'
}
Else {
New-ItemProperty -Path $currentPath -Name DisableAddonLoadTimePerformanceNotifications -PropertyType DWord -Value '1' | Out-Null
Write-Host -ForegroundColor Green 'DisableAddonLoadTimePerformanceNotifications created and set to 1'
}It gives me this output if the key/property exists:
Testing for: HKLM:\Software\Microsoft\Windows\CurrentVersion\Policies\Ext HKLM:\Software\Microsoft\Windows\CurrentVersion\Policies\Ext already exists. Disabling IE Add-On Performance Notifications (DisableAddonLoadTimePerformanceNotifications): DisableAddonLoadTimePerformanceNotifications already exists
However, this chunk does not work:
$currentPath = 'HKLM:\Software\Policies\Microsoft\Internet Explorer\Main'
$pathTest = Test-Path $currentPath
Write-Host -ForegroundColor Yellow 'Testing for: ' $currentPath
If($pathTest -ne 'True')
{
New-Item -Path $currentPath -Force | Out-Null
Write-Host -ForegroundColor Green 'Created Path: '$currentPath
}
Else{
Write-Host -ForegroundColor Red $currentPath ' already exists.'
}
If((Get-ItemProperty $currentPath -Name 'EnableAutoUpgrade' -ea 0).'EnableAutoUpgrade')
{
Write-Host -ForegroundColor Red 'EnableAutoUpgrade already exists'
}
Else{
New-ItemProperty -Path $currentPath -Name 'EnableAutoUpgrade' -PropertyType DWord -Value '0' | Out-Null
Write-Host -ForegroundColor Green 'EnableAutoUpgrade created and set to 0'
}Output if the key/property exists:
Testing for: HKLM:\Software\Policies\Microsoft\Internet Explorer\Main HKLM:\Software\Policies\Microsoft\Internet Explorer\Main already exists. New-ItemProperty : The property already exists. At C:\ps\setup\2.ps1:42 char:10 + New-ItemProperty -Path $currentPath -Name 'EnableAutoUpgrade' -Property ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ResourceExists: (HKEY_LOCAL_MACH...t Explorer\Main:String) [New-ItemProperty], IOException + FullyQualifiedErrorId : System.IO.IOException,Microsoft.PowerShell.Commands.NewItemPropertyCommand EnableAutoUpgrade created and set to 0
Output of the key/property does not exist:
Testing for: HKLM:\Software\Policies\Microsoft\Internet Explorer\Main Created Path: HKLM:\Software\Policies\Microsoft\Internet Explorer\Main Disabling IE Auto Upgrade (EnableAutoUpgrade): EnableAutoUpgrade created and set to 0
So, it'll create the property no problem, but can't see if it already exists.It looks to me like the If is failing on this one, but I can't figure out why. It's the same as one above it. In the full script I run a total of 14 registry entries. The ones above
`EnableAutoUpgrade` all work. The ones below `EnableAutoUpgrade` do not and fail with the same error.
This is happening on multiple machines all running Win8.1 and PowerShell v4.
This is a real head scratcher. Any help would be appreciated.
Hi,
This line is weird :
If((Get-ItemProperty
currentPath -Name 'EnableAutoUpgrade' -ea 0).'EnableAutoUpgrade')Try to replace it by :
If (((Get-ItemProperty -Path
currentpath -Name EnableAutoUpgrade).EnableAutoUpgrade)-eq 0)Is it better ?
