I have compiled the Windows console of Povray 3.8.0 beta 2 (povconsole64.exe)
but it seems that is not using all the cores of the CPU, but the Windows graphic
mode of Povray 3.8.0 beta 2 (pvengine64.exe) uses all the cores of the CPU, Wat
have to change in the source code of Povray 3.8.0 beta 2 to make the windows
console of Povray use all the CPU cores?

I don't know, but, maybe there is an option or directive of the compiler 
to enable multi-threading.

I truly wish I could help, but I am not a source-code programmer and have never
compiled a Windows app of any kind. But if you can get this to work correctly--
with the possible help of other users here who are more technically astute than
me-- it opens up the (later) possibility of fixing some of the code flaws that
currently exist in the 'official' v3.8.0 beta 1 and 2 compiled binaries.

The current 'official' Windows binaries by 'clipka' (Christoph Lipka) are the
latest ones we have, but they are several years old, with some code that was
'backtracked' to earlier versions for one reason or another...which reverted
some of the features to earlier flawed operation.

It would be great to have another Windows binary developer who could incorporate
some of the suggestions/fixes that have been mentioned in the newsgroups over
the past year, by myself and others (especially William Pokorny with his 'povr'
branch). Then 3.8 for Windows could finally be brought 'up to speed'!

Good luck with your efforts!

Also have been able to compile Povray v3.8.0 beta 2 for Windows XP, I have
tested it (Windows XP Service Pack 3) and works well

Solved, use option +WT4 (using a CPU with 2 cores) at the end of pvconsole64.exe
It seems pvengine64.exe uses all the cores by default, but pvconsole64.exe needs
+WTn parameter to use all the cores
