Test-RegistryValue check value

The Toolkit General Discussion

Hi
How can I use the “Test-RegistryValue” to check the version of value data?

HKEY_LOCAL_MACHINE\SOFTWARE\XXXX
values = version
value data= 1.2

I need to compare the value date.

Try this:
Test-RegistryValue -Key 'HKEY_LOCAL_MACHINE\SOFTWARE\XXXX' -Value 'value data'

If not, then try this:

Test-RegistryValue -Key 'HKLM:SOFTWARE\XXXX' -Value 'value data'

I wouldn’t use PSADT’s Test-RegistryPath for this. I’d use PowerShell’s built-in cmdlets. Something like the following. Obviously, you’d need to edit the variables to suit your scenario. The Path and Name below are from a script I recently wrote to disable missing PCs.

$RegPath = 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\'
$RegName = 'CachedLogonsCount'
$RegValue = $null

If (Test-Path -Path $RegPath)
{
   $RegValue = (Get-ItemProperty -Path $RegPath).$RegName
}
Else
{
   Write-Log 'The Registry path does not exist.'
}

Now that $RegValue contains the current value, you’d use an If or Switch to process the result.

If ($RegValue -eq 0)
{
   Set-Fire -To "$Computer"
}
Else
{
   Send-Flowers -To $User
}

-OR-

Switch ($RegValue)
{ 
  "0"
  {Set-Fire -To "$Computer"}
  "1"
  {Send-Flowers -To "$User"}
}
