Hi everyone ,
I'm happy to report that after a lot of trail and error I have managed to successfully track down the culprit of this issue.
It turns out those machines that have a USB dock use DisplayLink software - this causes a fault in conjunction with Windows 10 - went ahead and uninstalled the software and BINGO - everything is back to normal
Now just have to wait on the folks from DisplayLink to release different software/drivers or a patch to fix this if they haven't already done so :)
Really appreciate the follow up information on this, Eduard. I have and use a DisplayLink adapter with my XPS so this will have to get fixed with a driver update for it since uninstalling is not an option for my particular use case.
I guess now I can go hound the DisplayLink folks for a fix. Again, really appreciate your helping to narrow down the source of this frustration.
