After the installation is complete, you might be prompted to restart your computer.
Even if you are not prompted to restart your computer, it is always advisable to do so because the driver update process requires some changes to be made in the Windows registry, which are implemented only after your PC restarts.
There’s no reason to obsess about having the latest hardware drivers for every component in your computer. In particular, gamers will want to keep their graphics drivers as up-to-date as possible to ensure the best graphics performance and least bugs with modern games.
On Windows 7, 8, and 8.1, hardware drivers appear in the Windows Update interface as an optional update. Get your driver updates from Windows Update or your device manufacturer’s website.
