SOLVED! Microsoft OneDrive Stops Working after upgrading from Windows 7 to Windows 10

After upgrading my Windows from version 7 to 10, I noticed that Microsoft OneDrive stopped functioning. Status as "OneDrive not sign in". Nothing in settings can be adjusted, all options greyed (disabled). The sign in screen of OneDrive failed to load, with a message, "Loading..." and stayed forever...

To solve the problem, this is what I've done:

1. Start Task Manager (Windows Key+K), find "Microsoft OneDrive". (Press "More details" if you cannot find the app)
2. Right click on "Microsoft OneDrive" and select "Properties"
3. In the "Properties" of "Microsoft OneDrive", go to the "Compatibility" tab.
4. Check the box "Run this program in compatibility mode for", and select "Windows 7" from the list.
5. Restart your Microsoft OneDrive or restart your computer.

Similar approach to set "Compatibility" mode for other apps like Dropbox also works well.
