Acer Aspire netbook computers ship running the Windows operating system. In Windows, the applications that run on your computer are called "processes." If an unwanted process takes away valuable system resources and slows down your Acer Aspire, you can remove it and any other process using a native tool called the Task Manager.
Right-click on your Acer Aspire's task bar.
Select "Start Task Manager."
Select the "Processes" tab. This tab is in between the "Applications" tab and the "Services" tab. This shows you all processes that are currently running on your Acer Aspire.
Click on the name of an unwanted process and click "End Process" to remove it from your Acer Aspire.
