The Windows Update application Blocker, can help you turn off automatic updates on Windows computers, and version 1.2 has just been released.
The program was originally able to disable only the Windows Update service, but the new version seems to support others services, which can be set manually by one archive called wub.ini.
So Windows Update Blocker can now be used to block other Microsoft services, though it's not that simple since the wub.ini file needs to be manually edited.
But if you want to block only Windows Update it's extremely easy and this in itself blocks the automatic ones updates of Windows.
