I have never heard of this ASPNET until yesterday....Found that it was in my "USERS" 'Local System Accounts' along with>>'Help Assistant' & 'SUPPORT_388945a0'<<<<WTF Are they n How did they get there.....The only Microsoft Rubbish I download n install is/WAS Critickal Updates.DISSABLED Updates Over a Month ago...Has MicroRubbish Taken us all for a Wild Ride and Installed these with their so called SP2/3 without our knowledge!!?
I'm a Duffer!< >what is ASPNET< >What Does it DO<>What is it For.....
If ya Knows, Please tell me in PLAIN English...Either British or Yank will do..

Only Two things should be in my User Accounts n thats "My NAME" and "ADMINISTRATOR"...

Are those above what is giveing me problems!! Could this ASPNET or SUPPORT_388945a0 be the ones that is causeing my "Windows Explorer" to Stop Working and Close Down every so Often!!!!!
I have Dissabled them, Can I DELETE them, if so, HOW do I do It......
THANKS ALL.......

ASP .NET is installed along with the .NET Framework (which you most likely downloaded from Windows Update). You don't need it unless you are into web development and want to test ASP pages written with Visual Studio .NET. You can either disable it or delete it altogether if you wish, though it will do no harm at all if you just leave it there, it is highly unlikely to be the cause of your Explorer problems.

THANKS SuperSparks...Appreciated M8.
Do you know anything about that "SUPPORT_388945a0" thats in my USERS...

OK--I did a Google search on that last un....Still non the wiser on how or why its in my USERS.....But learnt a bit more----So much for SP2/3 updates that put what you don't need or want into our PCs....
