Here’s a piece of information we came accross, Microsoft have confirmed that the Vista service pack 1 won’t be available for download until march.
During beta testing for Vista service pack 1, Microsoft found that some device drivers were causing problems on some systems with service pack 1 installed.
Although the issues can be fixed by uninstalling and reinstalling the drivers, Microsoft decided this would be too complicated for most users.
So Microsoft are spending from now until March fixing drivers that are causing problems, and we have also learned that Microsoft have given OEM’s the disk images based on Vista service pack 1, so they can build their machines on the new service pack 1 format.
Microsoft have also started producing Vista service pack 1 on DVD for volume licensing.
Vista should be more stable after the service pack is installed. Wait and see
