Its finally done - ran from WU without any errors, etc. just took a very long time and for all the update it largely just meant resetting a few silly settings changes by MS and removed more **** like the silly people thing, etc. and reverting 1-2 other things.
EDIT: Is it me or is there some kind of built in mouse acceleration with this update? both my tablets used to have the same input feel and tweaked with MarkC's fix, etc. now since this update the pointer is all "swingy" and redoing the fixes doesn't change it though the registry stuff still seems valid and even undoing the fixes on my other tablet doesn't feel as bad
glad I don't have Windows 10 on my gaming PC.
EDIT2: Seems to be a known issue with enhanced pointer precision getting forced on or something
since the creators update that randomly affects people yay. How are MS this bad?
