The Vista DVD considered to be a security threat

The Windows Vista DVD is to be considered a security threat! By starting a computer from the Vista installation DVD and choose to Repair the computer instead of installing Vista, the user gets to a number of choices amongst them a command line (cmd.exe). By starting the command line tool you will have full access to all files on the computer and might easily copy them to a removable device of your choice. This is a big difference from Windows XP where you at least had to login to the Recovery Console with an administrator account, in Vista you just get full access to all the user and system files on the computer, no questions asked.

I however live by the principle that if anyone has physical access to a computer it might be compromised anyway, but still it is good to know about this potential security hole. Laptop computers might contain sensitive data and can easily be accessed by anyone who gain access to it if it should be stolen for example. The only way to my knowledge to protect from this “attack” is to use BitLocker (or possibly other encryption software). By using BitLocker the system partition is encrypted and you cannot access it using the method I describe above. If you install Service Pack 1 for Vista you will also be able to encrypt all partitions and disks on your computer, protecting your files and data further, not just the system partition. The BitLocker encryption function is only available with Windows Vista Enterprise and Ultimate Edition

Dell’s audio beta drivers necessary for deploying Vista

Anyone that has tried to integrate the SigmaTel audio driver that Dell provides for Vista in an install.wim has learned that the sound does not work after deploying that image. The effect is that the device seems to be installed correctly in the Device Manager but looking at the speaker’s icon in the notification area or from the Sound control panel just say ”No audio output device is installed”. This is a known bug in the SigmaTel drivers for all Latitude computers utilizing the SigmaTel audio chip, meaning all laptops from Latitude D610, D620 to D630 and all D4xx and D8xx versions as well are affected by the problem . Dell has given me a beta driver dated late July this year but they seem unwilling to give this to the public or to release a new stable driver. I suggest that anyone that experience this problem contact Dell and demand they release a new audio driver for SigmaTel audio cards as soon as possible. The driver  package number is R164710.

Service Pack 1 beats the record in restarts!

Service Pack 1 beats all previous records of the number of restarts a Service Pack requires. Normally the number of restarts to install a Service Pack is limited to just one (1) restart but with Vista this number is up to almost ten (10) restarts. First, you have to install a number of hot fixes one at a time just to be able to install SP1 as it requires certain fixes to make sure that nothing breaks during SP1. Installing SP1 itself also requires some five restarts or something like that before the installation is finished. As the SP1 is still in beta one could always hope that this number of required restarts would decrease as we reach the final version of SP1 but Microsoft has declined this. But prior to releasing SP1 Microsoft will start shipping the pre-requisite updates via Automatic Updates so that they are installed well in time before SP1 start shipping.
