Windows Vista x64 & kb932596
 

Do not install this update, reason? :
Be careful of the KB932596 "update" it stops the "bcdedit -set load options
DDISABLE_INTEGRITY_CHECKS" option working, that a lot of vista x64 users
were using to load unsigned drivers, and the associated MS KB article
doesn't see fit to mention the fact that this is probably the only thing
this ""update" does.
KB932596 definitely breaks unsigned drivers.
If you use google, you will see a lot problems with this update.

Regards.

Thanks Taos for the warning but it was too late when I saw your warning, now I know what was my problem :D

Enter into Programs & characteristics (programas y caracteristicas) under control panel (panel de control) add/remove applications.Then see installed updates (ver actualizaciones instaladas). Click in kb932596 and then uninstall. This will remove this bug. ;-)
Best regards to you, zipdecode.

taos:

I have posted your warning and solution on Woodmann's Forum, with credit to you. Thanks for the "heads-up." ;)

Regards,

Triple thanks. I'll have to add it to my "garbage to never integrate" list.
