The Navigation Pane, also known as the side panel in Windows 10 explorer is occupied by OneDrive folder prominently just below the Quick Access section. This is so because, OneDrive comes bundled with Windows 10 to help users store their documents and other data online in the cloud and sync it between your computers.
If you don’t use OneDrive, you can also remove this icon with a simple registry tweak. It should be noted that the setting won’t uninstall OneDrive from the system, it’ll just hide it from your File Explorer sidebar.
Remove OneDrive icon from Windows 10 Explorer
Press Win+R in combination to bring up the ‘Run’ dialog box. If prompted by UAC, click Yes and proceed further.
Then, navigate to the following key:
Searching the key can quite be a task especially, if the folder contains hundreds of entries. If you’re having trouble finding the key, Just move to Edit tab > Find in the Windows Registry menu, copy and paste the key, and then let the Registry Editor find for you take you the correct path.
Later, in the right-pane you should see a DWORD entry labeled System.IsPinnedToSpaceTree. Its value is set to 1. For removing the OneDrive folder from the side panel of Windows 10 Explorer, double-click on DWORD and set the value to 0.
Now, click OK to save your changes and then close the Registry Editor.
OneDrive will now no more appear in your File Explorer sidebar. If it does, try closing all the running programs and restart your computer. As mentioned earlier, the tweak doesn’t remove OneDrive from your system. It just removes or hides the OneDrive folder from your Windows 10 side panel of Explorer.
Here’s a screenshot of original Windows 10 File Explorer with OneDrive.
