Hi everyone
Please be aware of a know problem with Surface Book and the latest update, it would cause a BSOD of your OS.
The only recommended action is to reinstall a older version (Build 1709)
See an official’s statement:
When attempting to upgrade to the Windows 10 April 2018 Update, select devices with Intel SSD 600p Series or Intel SSD Pro 6000p Series may crash and enter a UEFI screen after reboot.
Microsoft is working with OEM partners and Intel to identify and block devices with Intel SSD 600p Series or Intel SSD Pro 6000p Series from installing the April 2018 Update due to a know incompatibility that may cause performance and stability issues. If you have encountered this issue, follow the steps to reinstall the previous operating system (Windows 10, version 1709).
Microsoft is currently working on a resolution that will allow the April 2018 Update on these devices in the near future.
