I'm running windows preview build 10049 , I logged on today to find some updates needed installing , so I proceeded to update the laptop , updates installed and I restarted the laptop with no issues , a little later on I logged off ,shut down and went back to windows 8.1 partition , to find windows update on there was corrupt after running the fix it tool , which was repaired , so I decided to log back on to preview to check updates on that OS , however when I tried to start it up the laptop started updating windows which produced this error fatal error c000003a update operation 4931 of 48516 ( 528f03 ) , when eventually the laptop started in stated it was unable to add the features and undid any changes , and I'm not sure I understand whats been happening during this process besides the obvious , I checked todays updates
