Get-ChildItem and registry key access not allowed
提问by rfgamaral
I'm trying to do a simple PowerShell script to access the registry and I'm doing it like this:
我正在尝试执行一个简单的 PowerShell 脚本来访问注册表，我正在这样做：
Foreach ($key in Get-Childitem HKLM:\SYSTEM\CurrentControlSet\Control\Class\"{4D36E972-E325-11CE-BFC1-08002BE10318}") {
$key.name
}
There's a bunch of keys that are just digits (the ones I want) but then there's one named "Properties" which I don't have access (I don't need to) and that key is giving me the following error executing the Foreach command:
有一堆只是数字的键（我想要的键），但是有一个名为“属性”的键，我无权访问（我不需要），并且该键在执行 Foreach 时给了我以下错误命令：
Foreach ($key in Get-Childitem HKLM:\SYSTEM\CurrentControlSet\Control\Class\"{4D36E972-E325-11CE-BFC1-08002BE10318}") {
$key.name
}

How can I exclude the "Properties" key and get rid of that error?
如何排除“属性”键并消除该错误？
回答by Keith Hill
If you just don't want to "see" the error then use the -ErrorActionon Get-ChildItem e.g.:
如果您只是不想“看到”错误，请使用-ErrorActionon Get-ChildItem 例如：
The SilentlyContinuevalue tells PowerShell not to display this non-terminating error. If you want to have PowerShell actually display the value for this key, you'll have to adjust the perms on the registry key.
该SilentlyContinue值告诉 PowerShell 不要显示此非终止错误。如果您想让 PowerShell 实际显示此键的值，则必须调整注册表项上的权限。
