I have to Validate Registry Value entry and need if entry is there, need to return the Registry Value Data.
So i have made an external Text file with Registry Path to be Validated.
Following is the Code to verify the Registry entry availability, but it does not work as expected.

Need Assistance in Validating and if Return the Value Data if Registry entry is available.

Code:
-------
function get
{
$RQ = Get-Content C:\Testing\PS\Reg.txt
foreach($RD in $RQ)
{
if(!(Test-Path -Path $rd))
{
Write-Host "RegValue Not Exists!"
}
else
{
Write-Host "RegValue Exists!"
}
}
}
get
