StumbleUpon

What is StumbleUpon?

StumbleUpon is a mobile app that can run on the BlueStacks App Player. The BlueStacks App Player lets you run apps from your phone fast and fullscreen on Windows.

Overview

The most common release is 2.1.7.5658, with over 98% of all installations currently using this version. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The setup package generally installs about 65 files and is usually about 21.22 MB (22,252,850 bytes).
