The best way to uninstall programs and save memory on your PC is to use the built-in program uninstaller, which can be found in the Control Panel. To open the Control Panel, press Win+X (Windows 8/10) or hit Start and search for “Control Panel.” Once you have opened it, select Programs and Uninstall a Program. You can then find and uninstall any programs that you don’t need. Furthermore, you can use a third-party software like CCleaner to clean up unnecessary files and optimize your PC’s performance.
