Re: "Windows update" leads to not booting

Hi polterkat,

The recent Windows update from the Microsoft has caused this concern. Please consider the following steps for issue resolution.

1. Restart by using the F8 key.
2. Select Repair your Computer.
3. Select the language, and then log on to the computer. 
           Note If you do not know the local password, you must start by using a Windows 7 DVD or USB bootable media. Then, access System Recovery Options.
4. Select System Restore from the menu: 
   
5. Restore the last restore point. This uninstalls security update 2823324.
6. Restart the computer into normal mode.

Also, you may refer to link below under section “Scenario B: Recovery steps for computers that have installed security update 2823324 and are now failing to start” for further steps if the above steps do not resolve the issue.
