UTILILAB SystemOPTIMIZER is a software program developed by UTILILAB. The most common release is 3.5.1000.15467, 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). When installed, it will add a context menu handler to the Windows shell in order to provide quick access to the program. The primary executable is named uso.exe. A majority of users end up uninstalling this less than a week of it being installed. The setup package generally installs about 45 files and is usually about 61.06 MB (64,023,280 bytes). The installed file USOCheckUpdate.exe is the auto-update component of the program which is designed to check for software updates and notify and apply them when new versions are discovered. Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows 8. While about 35% of users of UTILILAB SystemOPTIMIZER come from the United States, it is also popular in Iran and Egypt.
