Windows 7: Laptop shutdown during windows 7 update. Won't boot up now.

03 Mar 2016   #1

Windows 7 Home Premium 64bit
Laptop shutdown during windows 7 update. Won't boot up now.

During a windows update, my laptop shutdown unexpectedly and now shortly whenever it gets to the black screen with the windows logo, a blue screen pops up reading "session3_initialization_failed". It then restarts, giving me a choice to launch startup repair or start windows normally, the latter leading my to the same blue screen. I don't have any restore points for a system restore, and booting in safe mode does not help either. I would like to avoid reinstalling windows 7, just repair the system files, as I have important large files saved and did not make any backups. I have windows 7 Home Premium 64bit.

Also, before the shutdown, the screen read that it was at 15% configuring windows update.

Any help to a fix would be appreciated.
