Sharing is caring!

Microsoft has finally decided to push out some firmware updates for its Surface Pro 4 and Surface Book devices, although some users have complained that they were installing the patches, the installer crashed and a blue screen appeared saying “PAGE_FAULT_IN_NONPAGED_AREA (iacamera64.sys).” After the automated countdown ended, devices rebooted and the installer started running, but in short time, users saw another update notification listing “Intel Corporation driver update for Intel(R) Control Logic,” while other Intel driver updates failed to install, showing these errors: 800f0203 or 80248007.
