I am having trouble completing another update download on my x-64 based Surface Book with Windows 10. The previous update took a lot of special effort but 2018-3 KB4088785 did install and complete on restart. On ~3/21/18 I attempted to install a later update: Windows 10 update 2018-3 KB4089848. I was able to download and it did install, but on restart the update still says it is awaiting a restart. I continued to check for updates every day for the next 3 days and the Surface Book says there are no updates to install and the device is up to date. I have run the Windows update Troubleshooter and that software says that it could not detect a problem.
