When a user logs on, their registry profile at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\ contains a State Value Name, a REG_DWORD data type, that is a bit mask whose value indicates the state of the local profile cache.

NOTE: See tip 5346 ยป How do I retrieve a user's ProfileImagePath in batch?

The mask bits and their meaning are:

Hex Mask    Description
 0001       Profile is mandatory.
 0002       Update the locally cached profile.
 0004       New local profile.

 0020       Delete the cached profile.
