Here's another possible fix that seems to be working for a few users:Run CMD as administator (Go to start screen, all apps, search CMD, right-click and select run as administrator)
Enter: dism /online /remove-package /packagename:Package_for_KB2919355~31bf3856ad364e35~amd64~~188.8.131.52
When step 2 has completed, enter: dism /online /cleanup-image /startcomponentcleanup
Retry the update!
