how to find Active desktop Enabled\disabled?

[Manoj Chanchawat]

Hey,

I am into windows platform research. Can anybody tell me, how we can
determine "Active

desktop" settings from ShellState

(HKEY_USERS\S-1-5-XX-xxxx\Software\Microsoft\Windows\CurrentVersion\Explorer
ShellState).

i did a reverse engineering of this value data. It si Binary data. I found
that the 5th

Byte in ShellState is changing everytime i change active desktop status
(enable or

disable).
- Am i right by saying that this 5th BYTE only decides the active desktop
status?
- Also, am i right by saying that the 7th Bit of this 5th BYTE is mainly
responsible to

change Active desktop enable and disable?
- Is it applicable for all windows OS 2000 and above?

thanks in advance for your time and reply.
