Intel SBA

Intel® Small Business Advantage (Intel ® SBA) provides an out-of-the-box hardware-based security and productivity suite designed for the small business user. Intel SBA includes a customizable user interface and several bundled Intel applications.

Prerequisites

■ Supported Operating Systems

Intel SBA supports following OS:

■ Windows 7 Professional 64-bit and 32-bit
■ Windows 7 Enterprise 64-bit

■ Required User Permissions

You must run the installer and the customization wizard with a user that has local administrator permissions on the computer.

■ Windows Update Settings

In certain conditions, the Windows Update task in the PC Health Center application is disabled and cannot be enabled. This can occur if Intel SBA is installed on a computer where Windows Update was disabled during installation of the Windows operating system. The Windows Update task is shown in the GUI but is grayed out (disabled). Even if the end user enables Windows Update in the operating system, the PC Health Center task cannot be enabled. This means that the end user cannot use PC Health Center to manage Windows Update.

To prevent this, make sure that you do NOT select the Never check for updates option when installing the Windows operating system.

■ Windows Task Scheduler

Some PC Health Center tasks are applications that can also be used directly from the operating system and scheduled via the Windows Task Scheduler. When a task is set via PC Health Center, an alarm clock is set that will wake up the computer if it is turned off. Defining a scheduled time for an application/task outside of PC Health Center does not set an alarm clock. This means that the computer will not be woken up to do the task.

For this reason, it is NOT recommended to define schedules for these applications:

■ Windows Updates
■ Windows Backup and Restore
■ Disk defragmentation

Instead, let the end user set the schedule for all these tasks via PC Health Center.

Installing Intel SBA

This procedure describes how to install Intel SBA.

■ To install Intel SBA:

  1. Logon to the computer with a user that has administrator privileges.
  2. Insert the application DVD into the DVD-ROM drive. The setup screen will automatically appear.
  3. Click OTHERS tab.
  4. Select Intel SBA to start installing.
  5. Follow the on-screen instructions to install.

Software Configuration
