5.4 Software Problems 5.4.1 End Program You may end a program from task manager if you cannot exit the running program normally. You may invoke Task Manager window by pressing Ctrl, Alt and Delete at the same time. To end a program, select it in the Application tab, then click End Task button. 5.4.2 Install and Uninstall Program Appropriately Install Program Appropriately If possible, never stop the process illegally during installation (for example, cut off the power supply). This might lead to system program chaos, and even failure to enter the system normally. Uninstall Program Appropriately If you need to remove certain applications, never directly delete the files or folders. This is harmful to the system, and might lead to system crash. Follow the procedure below to uninstall program appropriately (backup all documents and system settings related with the program before removing the program): Step 1 If the program has its own uninstaller, run it directly to uninstall the program. Step 2 If not, click Start in the lower left corner of the desktop, and then click Control Panel in the popup menu. 76 Lenovo 3000Q User Guide
