Windows 10 Removing things that appear after right-clicking a file

This appears when we right-click on a file. However, this right-click often takes too much time.

I googled and found out Fix for Very Slow or Hang When Right Click On a File or Folder • Raymond.CC. It says I need to use ShellExView, which would allow me to delete some things that appear here.

This is what appears if I open ShellExView. But I can't figure out which one is which. I want to remove that "Import to Grammarly" , "Share with Skype" , and I don't even know what "Cast to Device" and "CRC SHA" means. How can I tell?
