OS: Microsoft Windows 10 Home - 64 bit
Version: 10.0.15063 Build 15063
Model: HP Spectre x360 Convertible 13-ac0XX
Type: x64-based PC
When Windows update attempts to install KB4038788, it downloads the patch, says to reboot to install. I reboot. The update appears to install after a reboot. Once the system performs a final reboot, Windows detects there was an issue with the patch and rolls it back. Since updates are automatic, this process repeats ad infinitum.
Downloading the patch from Microsoft directly and installing is a disaster. The patch appears to install, then upon reboot, the system cannot find the boot drive. Recovering to a system restore point will rescue the system, but the patch is then no longer installed.
sfc /scannow finds there is some corruption that cannot be repaired, but it is isolated to .wav files. The wav files do not match a particular hash, nor do the replacement files. It seems likely there is an error in the hash itself, not the files, since sounds work as designed.
Has anyone else had issues with this Cumulative Update?
