[Powershell] Removing the NXLOG-agent without the Nagios management interface.

I made this script at the request of a colleague, who needed a quick way to remove the NXLOG-agent without having to resort to the management interface (which was unavailable).

##		Define the path where the key should be located and start a recursive search
##		The script only looks for a registry key containing the right display name and publisher, and selects the LocalPackage property.

$inst = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\* -Recurse | Get-ItemProperty | 
		Where-Object {$_.DisplayName -like 'NXLOG-CE' -and $_.Publisher -like 'nxsec.com' -and $_.Publisher -ne '' } |
		Select-Object LocalPackage -ExpandProperty LocalPackage

## 	Silent install of the package, required for the next step

Start-Process $inst -arg '/q' -Wait

##	 Silent uninstall of the agent

Start-Process "msiexec.exe" -arg "/X $inst /qn" -Wait

This script could also be modified quite easily to run on a remote computer by adding the following at the beginning of the script:

$PC='SRV-NAME-01'

Invoke-Command -ComputerName $PC -ScriptBlock {

In this case, don’t forget to add a } in line 21.
