To remove a program from your computer, follow these steps:
- Click Start, click Control Panel, and then click Add or Remove Programs.
- In the list of programs, click the one that you want to remove, and then click Change/Remove.
- Click Yes when you are prompted with the question "Do you want to remove the program?"
If the program is not listed in the Add or Remove Programs tool, contact the manufacturer to obtain instructions for removing it.
