Windows 10: How to eliminate the many redundant entries in Win Explorer 10?

Please provide me some guidance to eliminate the redundancies in my Win Explorer left pane. I work mainly out of Libraries but there's so much clutter that it's just not quick and easy to get to my important stuff. For example:My drives are listed both under This PC and for two of them also under Desktop. How can I group them all under Desktop and eliminate the separate entries under This PC?For that matter, This PC is entirely useless because everything under that major entry is more logically shown somewhere else in the tree. How do I remove This PC?OneDrive shows up in three places:

Eliminate One Drive

Ran the CMD file (As Administrator). Restarted Win 10. Still listed in File Explorer.

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Eliminate One Drive

Update. I clicked on the One Drive entry in the File Explorer and get an invalid. So one drive must be gone just the listing of it in the File Manager was not removed.
