I am running ZASS version on Vista and the Windows Automatic update appears to be blocked by ZASS.

The Windows download icon appears, however the download does not progress beyond 0%.
The Windows Download box freezes and remains blank.
It can only be stopped from downloading ( nothing ) by doing a Control-Alt-Delete.
I stopped ZASS from loading at Start-up, re-booted, and the Windows Update immediately commenced and successfully downloaded, and then installed, today's important Microsoft update.
Can any one please help me to understand what are the correct ZASS settings to allow Windows Update to correctly function?
Any help will be much appreciated.

Operating System:Windows Vista Home Premium
