I really thought the names of user accounts would be seen in the Users folder, but aside from the recognized "user accounts" of my own, Public, and Administrator, I have the following:

.NET v4.5
.NET v4.5 Classic
All Users
Default
Default User
Default.migrated
DefaultAppPool
TEMP
UpdatusUser

Yes, I am showing hidden folders here, but can I / should I blow away any of these? If I could at least justify a folder as being some form of system account such as maybe "All Users", but items such as the .NET accounts strike me as just plain weird.
