Because the Battle.net uninstall string does not support silent parameters, we created a PowerShell script that removes the application completely, including any leftover files and registry entries.
1. Save the removal script as a .ps1 file, for example remove-battlenet.ps1
$processNames = @("Agent", "Battle.net")
$pathsToRemove = @(
"$env:LocalAppData\Battle.net",
"$env:LocalAppData\Blizzard Entertainment",
"$env:AppData\Battle.net",
"$env:ProgramData\Battle.net",
"${env:ProgramFiles(x86)}\Battle.net",
"$env:ALLUSERSPROFILE\Microsoft\Windows\Start Menu\Programs\Battle.net*",
"$env:PUBLIC\Desktop\Battle.net.lnk"
)
$registryPaths = @(
"HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Battle.net"
)
function Test-BattleNetPresent {
foreach ($proc in $processNames) {
if (Get-Process -Name $proc -ErrorAction SilentlyContinue) {
return $true
}
}
foreach ($path in $pathsToRemove) {
if (Test-Path $path) {
return $true
}
}
foreach ($regPath in $registryPaths) {
if (Test-Path $regPath) {
return $true
}
}
return $false
}
function Remove-PathIfExists {
param (
[string]$Path
)
if (Test-Path $Path) {
Remove-Item $Path -Recurse -Force -ErrorAction SilentlyContinue
Write-Host "Removed: $Path"
}
else {
Write-Host "Not found: $Path"
}
}
function Remove-RegistryIfExists {
param (
[string]$RegistryPath
)
if (Test-Path $RegistryPath) {
Remove-Item $RegistryPath -Recurse -Force -ErrorAction SilentlyContinue
Write-Host "Removed registry key: $RegistryPath"
}
else {
Write-Host "Registry key not found: $RegistryPath"
}
}
if (-not (Test-BattleNetPresent)) {
Write-Host "Battle.net is not installed or no related files were found. Nothing to do."
exit 0
}
Write-Host "Battle.net detected. Starting cleanup..."
foreach ($proc in $processNames) {
$running = Get-Process -Name $proc -ErrorAction SilentlyContinue
if ($running) {
Stop-Process -Name $proc -Force -ErrorAction SilentlyContinue
Write-Host "Stopped process: $proc"
}
else {
Write-Host "Process not running: $proc"
}
}
foreach ($path in $pathsToRemove) {
Remove-PathIfExists -Path $path
}
foreach ($regPath in $registryPaths) {
Remove-RegistryIfExists -RegistryPath $regPath
}
Write-Host "Cleanup complete."
exit 0
This PowerShell script:
- stops Battle.net-related processes if they are running
- checks whether Battle.net or related leftovers exist
- removes known Battle.net folders
- removes Start Menu and Desktop shortcuts
- removes the uninstall registry key
- exits cleanly if nothing is found
2. Create a tag for Battle.net hosts
For easier targeting, you can create a dedicated tag for hosts with Battle.net installed
https://corporate.vulndetect.com/#/tags
3. Filter hosts from the Applications page
From the Applications page, filter the hosts with Battle.net installed and assign the tag to them.
https://corporate.vulndetect.com/#/applications
4. Create the Custom Software deployment
Create the custom configuration and upload the removal script as a .ps1 file
https://corporate.vulndetect.com/#/deployment/custom-create-job
5. Deploy the Custom Deployment Job to the target tag
Run a manual inspection after deployment if you want the results to appear immediately.
