I can't 'restore' some features

I'm tryng to return to windows 10 theme, but it doesn't work perfectly

I used this
www.winclassic.net/thread/204/automatic-classic-theme-script-windows
and classic shell and remove classic shell now.

right click menu and few toolbars keep greyish color.. and cursor speed feels like became slower?
does someone have clean backup for original theme?
