ESU for Microsoft Windows 7 SP1

What is ESU for Microsoft Windows 7 SP1?

This package installs Microsoft fixes and enhancements for the Microsoft 7 Operating Systems, as well as providing other fixes and enhancements that are specific to the listed notebook models. These fixes and enhancements are required to improve the performance of these notebook models.


The most common release is 2.1.1, 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. It adds a Browser Helper Object (BHO) to Internet Explorer. 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 primary executable is named sbamui.exe. The setup package generally installs about 417 files and is usually about 3.51 MB (3,679,232 bytes). The installed file softwareupdate.dll 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.
