How to Check If Registry Key Exists in PowerShell

To check if a registry key exists in PowerShell, you can use the Test-Path cmdlet. This command checks if an item exists at the specified path, including the registry keys.

The following example shows how to do it with syntax.

$registryPath = "HKLM:\Software\SysApp"

if(Test-Path $registryPath){
    Write-Output "Registry key exists"
} else {
    Write-Output "Registry key doesn't exists"
