But take heart. There are a lot of things you can do to keep your computing troubles to a minimum. Programs that came with your computer as well as programs you install make extensive changes in several Windows files. Delete a program from your computer and you will leave those changes in place, setting the stage for a wide assortment of problems. The preferred way to get rid of programs is to uninstall them.
Some programs come with uninstall utilities.
If a program does not have an uninstall option, use the Windows Remove utility. Highlight the reference to the program. These programs are more thorough than Windows Remove. Respect the Shut Down process. Never shut off your computer just by turning off the power.
