Netbook Optimizer


Netbook Optimizer is a software program developed by Systweak Inc. During setup, the program registers itself to launch on boot through a Windows Schedule Task in order to automatically start-up. 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. The primary executable is named nbo.exe. The setup package generally installs about 42 files and is usually about 45.89 MB (48,122,359 bytes). The installed file NBOCheckUpdate.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 7. While about 53% of users of Netbook Optimizer come from the United States, it is also popular in Australia and AO.
