# PowerShell Script to remove Intel Killer Performance Suite (KPS)

#
# *** MUST BE RUN FROM WINDOWS POWERSHELL AS ADMINISTRATOR ***
#
# 1. Click Start
# 2. Type "PowerShell" and choose "Open as administrator"
# 3. To run this, enter: .\killer-killer.ps1
# 
# KPS adversely affects networking performance and is not necessary
# for proper operation under Windows. It is difficult to remove, 
# but it can be disabled, hence this script.
#
# The KPS driver is an optional update that can be installed via: 
#
# Settings > Windows Update > Advanced options > Optional updates
#
# It appears as a generic "SoftwareComponent" entry, like this:
#
#      "Intel Corporation - SoftwareComponent - 3.1523.1205.1"
#
# KPS has that version number or a later one that is similar.
# You can avoid it coming back by omitting this particular
# SoftwareComponent when installing optional updates.
#

# Get all services related to Intel Killer Performance Suite
$services = Get-Service | Where-Object { $_.DisplayName -like "Killer *" }

# Check if any services were found
if ($services.Count -eq 0) {
	Write-Host "No Killer Performance Suite services are currently running."
} else {
	# Stop each service, disable it, and remove it
	foreach ($service in $services) {
		Write-Host "Working on service '$($service.DisplayName)' ..."

		Write-Host "     ... Stopping '$($service.Name)'"
		Stop-Service -Name $service.Name -Force

		Write-Host "     ... Disabling '$($service.Name)'"
		Set-Service -Name $service.Name -StartupType Disabled

		Write-Host "     ... Removing '$($service.ServiceName)'"
		C:\Windows\System32\sc.exe delete "$($service.ServiceName)"
	}

	Write-Host "All Killer Performance Suite services stopped and disabled."
}

#
# OPTIONAL: Remove the RivetNetworks directory (contains Killer subdirectory)
#
# *** REMOVE THE # BEFORE Remove-Item BELOW TO ENABLE THIS! ***

# Edit this path if different on your system
$driver = "C:\Windows\System32\drivers\RivetNetworks"

# Check if the directory exists before attempting to remove it
if (Test-Path $driver) {
	Write-Host "Removing $($driver) directory..."
	#Remove-Item -Path $driver -Recurse -Force

	# Check if the directory still exists after removal
	if (Test-Path $driver) {
		Write-Host "Directory $($driver) still exists."
		Write-Host "If failed due to open files, restart and run this again, or delete it manually."
	} else {
		Write-Host "Directory $($driver) successfully removed."
	}
} else {
	Write-Host "The directory $($driver) does not exist. Skipping removal."
}
