Bug

UninstallServiceAsync uses Thread.Sleep(500) in a polling loop while waiting for a service to stop:

while (sc.Status != ServiceControllerStatus.Stopped && DateTime.Now < waitUntil)
{
    Thread.Sleep(500); // Blocks thread pool thread
    sc.Refresh();
}

Since this is an async method, Thread.Sleep blocks the thread pool thread instead of yielding it.

Impact

Under load (e.g. bulk uninstall operations), this can exhaust thread pool threads and degrade application responsiveness.

Suggested fix

Replace with await Task.Delay(500).
