Remove OneDrive from File Explorer Side Panel in Windows 10

On my work PC, I use OneDrive for Business instead of OneDrive. By default Windows 10 includes an OneDrive shortcut in File Explorer side panel.

Change the following registry key to remove it.

• {HKEY_CLASSES_ROOT\CLSID\{018D5C66-4533-4307-9B53-224DE2ED1FE6}
• In the subkey System.IsPinnedToNameSpaceTree change the DWORD from 1 to 0
• No reboot required.
