Subtitles of the Movie (Microsoft Windows Server 2003 (70-290) / Managing Device Drivers / Driver Rollback)
If you worked on computers for any time what so ever you have done some thing that you wish you had not done and you can't just want to roll back the clock. That is what driver rollback is all about. If we have installed a driver that we now have decided we really should not have installed, it is really not doing any better in fact it is worse than we can get back to where we were. Now we can get back to where we were by going back to last known good configuration. However if we use last good known configuration we will go back to where we were at the last successful logon. So say we have made changes to many things and we have installed multiple drivers by tweaking out of server and then we install one more thing just want to make it just a little bit better you can make the video just a little bit crisper, may be install a new Network Interface Card that may be gives us just a little bit better performance and then all of the sudden we have got very bad video or we have got no network performance or less network performance than we have before. And what we want to do is just undo that last change. Well, the way that undo that last change would be either use last good known configuration in which case we are going back to where we were at the square one when we logged on to the system. Which is probably what we do not want to do or we need to completely uninstall the drivers that we just installed which some times sounds easier than it actually is, and then we would need to re- install the original driver that we had before. Assuming that we can find the software that we had before the original software the original driver might even have been installed by the operating system. It might have been installed by the initial installation. So we really do not have the driver or do not know where. It might be in a cabinet file some where we would have to extract it. So being able to rollback to the driver that we had before is a nice feature. And it is an easy thing to do if we go into our system click on start then control panel then system and then hardware and let us go to device manager. Let us go back to our DVD CDROM and we are going to then right click on it and go to properties. So bring up the properties for our Samsung CDRW and if we wanted then to look at the drivers click on the driver tab, if we wanted to roll back to the previous driver that, that device was using we will click on roll back driver. Now I have not had problem with this so I have not updated the drivers. So let us take a look at what will happen if you click on a roll back drivers and there is nothing to roll back to. The system says no driver files have been backed up for this device so if you are having problems with these you should use troubleshooter information. But if we had updated the driver if we have used the driver updates then we would be able to roll back to previous driver, because system makes a backup of the other drivers. So it is nice to be able to roll back to the drivers when we need to. It is nice to have the signed driver files and we really need to know a little bit more about how we would identify drivers, identify signed drivers versus unsigned drivers. So in our next section take a look at file signature verification. That is next.
