Thread Environment Block (Debugging Notes)

The Thread Environment Block (TEB structure) holds context information for a thread.

In the following versions of Windows, the offset of the 32-bit TEB address within the 64-bit TEB is 0. This can be used to directly access the 32-bit TEB of a WOW64 thread. This might change in later versions of Windows

Platform	Version
Windows Vista	Windows Server 2008
Windows 7	Windows Server 2008 R2
