Glad it's working! Thanks @lxp as I didn't think of doing it that way.
@bssmith : It might be worth re-blocking the shell extension and checking if things still work without it. If they don't, un-block it again, of course!
(It's blocked by default as it probably isn't needed anymore and sometimes causes a delay when opening folders. Bit more detail just before the 2nd heading (at time of writing) in Shell extensions which are blocked by default )
