I have just purchased WB10 and all works well except that the Taskbar won't skin at all. I also have Start 10 installed. Previously, way back to the Technical Preview of Windows 10, and before the notices went up in this forum about WB not being compatible, I installed WB8, and used the compatibility mode, as someone here suggested.  It has worked fine in this way, other than that the Taskbar wouldn't skin - which I put up with. Before installing the newly purchased WB10 a couple of days ago I uninstalled WB8, rebooted, cleaned up the files that were still on the system, and did a thorough registry clean to try and eliminate all signs of the previous version.  But, as I say, the Taskbar still remains unskinned.  Is anyone else having this problem - and has anyone got suggestions as to how to proceed?
