  • Go to Programs and Features, by search "Start" for "Programs and Features".
  • Scroll to Sony PC companion and  uninstall it.
  • After uninstallation, scroll to "Sony Mobile Update Engine" and uninstall that too.
  • Optional: You can also clear out the "C:\Users\All Users\Sony\Sony PC Companion", you can delete the folder "Sony Pc Companion Folder itself".
  • Restart


Now you can redownload PC Companion from support.sonymobile.com.
