I use a NEO Z83-4 with latest bios 1.6. When I started the windows 10 assistant to update to the windows creator update, after a while I received an error code: 0xc1900200 I've been googling it and found a resolution to it. The first reserved system partition is actually too small and prevents the win update. The idea is to enlarge it to around 500 MB instead of 100 MB. There is a free version of a partition tool to make the space: free MiniTool partition wizard: https://www.partitionwizard.com/free-partition-manager.html Install and run the tool, then move the main big disk partition to the right by reducing its size of about 0.5 GB then move it to the right. Apply and reboot. After reboot and tool execution, There will be a free partition created in between and another small reserved partition(which was already present, named MSR Partition). You can delete that second small partition (MSR Partition) and you will be able to expand the most left partition (System Reserved partition) to the right till the big main partition (that will be around 500 MBytes then). apply and reboot and now windows creator update will install properly.
