Here is a solution for updating KB2770917 that workes.
Here are the steps to follow:
Hit windows key + R to open Run command.
Type in msconfig.exe and hit enter
go to the Services tab on the top
Check the box on the bottom that says hide all microsoft services
Click Disable all
Restart the computer
After installation follow the same instructions but click enable all instead of disable all and restart again and everything should be good. Hopefully it works.
