Hi Myrtle Folston,
For apps you do not recognize, I recommend checking the app name and publisher before removing it. Some entries may be components installed by your PC manufacturer, hardware drivers, or other software and may still be required even if you do not open them directly.
If an app is unfamiliar, please share its exact name here and we can help determine whether it is generally safe to remove.
I hope this helps you clean things up without accidentally removing something your system needs.
