• To update your Surface with the latest drivers and firmware from the Download Center, select the .msi file name that matches your Surface model and version of Windows. For example, to update a Surface Book 2 with build 15063 of Windows 10, choose SurfaceBook2_Win10_15063_1702009_2.msi. For a Surface Book 2 with build 16299 of Windows 10, choose SurfaceBook2_Win10_16299_1703009_2.msi.

If there's not an .msi file that corresponds to the build of Windows 10 you have installed, select the .msi file that's closest to (but still lower than) your build number.
