Multiple directories are opening when starting my computer

When I start my computer, I am getting multiple directories opening up. Mostly D and one or two My PC. I have gone into settings and tried everything to stop them from opening. I asked ■■■■■■■ and tried what was recommended. Nothing seems to work. Any suggestions. Thanks

If you turn off Explorer Replacement in Opus and reboot, do the windows still open? If so, do they open in Opus or File Explorer?

(Preferences / Launching Opus / Explorer Replacement)
