After installing Windows 8.1 preview release, there's a
ASP.NET Machine Account at the Start screen. I don't remember seeing it before the 8.1 install. Now the question is how do I remove it from the list without removing or disabling the account?

regeditand press Enter.

Previous answer hasn't worked for me, so I disabled Fast User Switching.
Open regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Look for a value called “HideFastUserSwitching“. If it does not exist, right-click the “System” folder, select “New DWORD 32-bit value“, then type a name of “HideFastUserSwitching“. Press “Enter” to create the value.
Double-click “HideFastUserSwitching“. Change the “Value data” to “1” to disable Fast User Switching.
