I have just tried the WIN10 1903 update but after installation Windows reports "Your PC/Device needs to be repaired error code 0xc000000f" in a pale blue screen. The repair action checked the BOOTCAMP disk and found no errors. Other recommended key options did not work. This blue screen disappears after about 30 seconds. I managed to restore the previous version WIN10 1803 using a Winclone backup so I am running again but reluctant to keep fiddling with this upgrade so have deferred. I am running Parallels desktop V14 in MacOS Mojave on 2018 13" MacBook Pro. Has anyone had this experience? Any fixes out there? Should I perhaps run BOOTCAMP natively to perform the upgrade?
