My latest "fix" (which didn't work) was running the Windows Readiness Tool , then I had a downloaded copy of SP1 on disc , ran the setup , same error.Once you have the details you can search the manufacturers website for your drivers and, if available, download and install these drivers.If you are unsure of whether or not you need to update your Drivers, or indeed which Drivers may need to be updated, you can run a Drivers scan using a driver update tool (you will need to pay to register this tool but usually the Drivers scan is free).As for someone who has a lot of applications and drives as does not have the time to manually update them, I strongly recommend Driver Booster, it will help to update the driver quickly and easily.""This is one of the best driver updater programs around. Microsoft has even led me astray by suggesting updates that wouldn’t work with my machine. I do not want to format this machine and start fresh.
