Like previous versions of Windows, File Explorer has a space-wasting OneDrive icon in the left sidebar.

If you dont use OneDrive, you’re able to remove this icon with a simple registry tweak.

Remember: this wont remove OneDrive from the system, itll just hide it from your File Explorer sidebar.

Double-click onSystem.IsPinnedToNameSpaceTreechange its value from1to0.

Log off or reboot your rig.

When you open File Explorer, the OneDrive entry should be gone from the list.

Enjoy your cleaner, easier-to-navigate sidebar!
