Built-in hardware driver winxp is greater than win7

A friend who has installed win7 knows that almost all the hardware can be used normally after the win7 installation is completed. However, analysts pointed out that Windows 7 has less built-in hardware drivers than Windows XP, mainly through the Internet to download drivers, but this new approach also has certain shortcomings. In order to be lightly loaded, Windows 7 has fewer built-in hardware drivers than Windows Vista and XP, and mainly relies on Windows Update to download from the Internet, but what if Windows Update cannot find a matching driver? Windows 7 Ultimate users complained that he tried to install an HP printer. After Windows 7 found no results in the local driver library, and then found through Windows Update, still did not find a matching driver. The user had to download a 40MB installation package from the HP website. Obviously, this is not a simple driver, otherwise the file size will not be so large. Therefore, Windows 7 is a key to the success of Windows 7.
