Checking if registry value is equal to 1 is not working correctly
提问by user2593163
I have slopped together bits of PowerShell to remote query a list of machines, stored in a .csv file, for a registry value. If the registry key's value is equal to '1', the script should then create a text file using the machine's name as the name of the text file.
我已经将 PowerShell 的各个部分放在一起，以远程查询存储在 .csv 文件中的机器列表以获取注册表值。如果注册表项的值等于“1”，则脚本应使用机器的名称作为文本文件的名称创建一个文本文件。
Everything works great. The script runs happily without any errors. The problem is that when I go back and remotely check a targeted registry value, I find that the value isn't 1. The script is simply creating a file for every line in the .csv.
一切都很好。脚本运行愉快，没有任何错误。问题是，当我返回并远程检查目标注册表值时，我发现该值不是 1。脚本只是为 .csv 中的每一行创建一个文件。
What am I doing wrong?
我究竟做错了什么？
EDIT*** I found aproblem I had a typo in the $key variable for the registry path. 7/17/2013 2:21p
编辑*** 我发现了一个问题，我在注册表路径的 $key 变量中有一个错字。2013/7/17 2:21p
$File = Import-Csv 'c:\temp\machines.csv'
foreach ($line in $file)
{
$machinename = $line.machinename
trap [Exception] {continue}
$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey("LocalMachine",$MachineName)
$key = "SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon"
$regkey = ""
$regkey = $reg.opensubkey($key)
$keyValue = ""
$keyValue = $regKey.GetValue('AutoAdminLogon')
if ($keyValue = "1")
{
try
{
$textFile = New-Item -Path "c:\temp\autologin" -Name $MachineName -ItemType "File"
}
catch
{
$msg = $_
$msg
}
}
$Results = $MachineName , $keyValue
Write-host $Results
#Output Below Here:
}

In PowerShell =is an assignment operator, not a comparison operator. Change this line:
在 PowerShell 中=是赋值运算符，而不是比较运算符。改变这一行：
if ($keyValue = "1")
into this:
进入这个：
if ($keyValue -eq "1")

You're making this way too complicated, BTW. Something like this should suffice:
你让这种方式太复杂了，顺便说一句。这样的事情应该足够了：
$keyname = 'SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon'
Import-Csv 'C:\temp\machines.csv' | % {
$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey("LocalMachine",
$_.machinename)
$key = $reg.OpenSubkey($keyname)
$value = $key.GetValue('AutoAdminLogon')
if ($value -eq "1") {
$filename = Join-Path "c:\temp\autologin" $_.machinename
try {
touch $filename
$textFile = Get-Item $filename
} catch {
$_
}
}
Write-Host ($_.machinename , $value)
}
