I10 CWI527 Screen won't adjust brightness after Windows Reinstall

I recently did a clean install of Windows 10 and on top of having 2 unknown devices in my Device Manager, the slider to adjust the screen brightness appears but it doesn’t actually change the screen brightness.

My tablet is a dualboot Hi10 CWI527 LQ64G42170900555.

You should have made a copy of your tablet drivers before reinstalling the system.
Here is a link to download the supported drivers: https://onedrive.live.com/?authkey=!AJ_jCJ1PHwsR8mk&id=FC1F543E3FBD4AAA!8286&cid=FC1F543E3FBD4AAA
