Appreciate the help. Milo (again). Questions:-
- I read repeatedly that .net is 'central' to the Windows OS and that programmes will use one version or another, yet removing it has no effect? I have zero understamnding of .net frameworks!
- will sfc replace a .net version on my machine if I remove all, and if so which one (SP3)?
- does catroot hold ALL updates or just .net? BTW I have separate catroot AND catroot2 folders with different subs??
