Does it mean this happened to everybody who has removed Internet Explorer, which IECore is part of it? How much disk space will be needed if IE is added back? (I won't do it, just want to know a little more.) Thx What I_Broke_My_MHZ is saying is that, since you don't have IE any more (eg IECore) the Standard User Accounts window won't work properly, so instead with the reg hack stated above, you'll use the other User Accounts manager within windows Without needing to install IE.
