Does anyone know when Microsoft will release a patch for this?

My new Toshiba Satellite came with Windows Vista Home Premium pre-installed.
I didn't had any problems until the second time I ran Windows Update

The first time I only installed critical updates, and after the reboot,
everything looked fine.

However the second time, I installed the others updates and after the reboot
Vista hanged up, eternally showing the loading message "please wait..." :( :(

I had to manually reboot, enter Safe Mode and restore the system... Now I've
disabled Windows Update until future news.

It seems that I'm not the only one with this problem.... any suggestions?

thanks!
