Troubleshooting software problems
Problem: You are unable to exit a running program normally.
Troubleshooting and problem resolution:
1. Press the Ctrl, Alt and Delete keys at the same time, then select the Task Manager
option from the Windows logon screen.
2. Select the problem program, then click the End Task button.
Problem: You need to install or uninstall a program.
Problem resolution:
During installation never abort the install process by powering the system off or
through other drastic means. This can cause system program problems or even failure
during system initialization.
During the uninstall process, never directly delete the files or folders. This is harmful
to the operating system, and might cause a system-wide malfunction. Use the following
procedure to properly uninstall programs:
1. Back up all documents and system settings related to the program before removing
it.
2. If the program has its own uninstaller, run it directly to uninstall the program.
3. If the program does not have its own uninstaller, use the search box on the taskbar
to open the Control Panel.
4. From the Control Panel, choose Programs → Programs and Features.
5. Find the program in the Programs and Features dialog box and then select
Uninstall/Change.
6. Follow the prompts displayed to uninstall the software.

Otherwise, continue with the next step of this procedure.
