Please run this PS script as an automated task from the Pulseway WebApp, but note, that this script will not work if the Pulseway agent is installed only for one user:
$result = gwmi win32_product -filter "Name LIKE 'Pulseway'" | select IdentifyingNumber;
[string] $a = $result.identifyingNumber;
msiexec.exe /X $a /qn
Remove-Item -Path "HKLM:\SOFTWARE\MMSOFT Design" -Recurse
Write-Host "Uninstallation completed successfully"
Or you can uninstall the Pulseway agent using the Pulseway mobile app -> Applications -> Pulseway -> tap on the name Pulseway and select option 'Uninstall'. Note, this will not delete the configuration for the Pulseway agent from the system.
