There was a power outage during windows update (Windows 7). My computer will not boot now. It has the "starting windows" screen, but then goes to the blue screen and it keeps giving me the error: "A process or thread crucial to system operation has unexpectedly exited or been terminated". See attached for screenshot. Then it asks to either "launch startup repair" or "start windows normally". When I try the startup repair, I try all of the items, but nothing works. I can get to setup and boot menu. Locked Question. This question was migrated from the Microsoft Support Community.

Sorry for the late reply, but I was trying all of the steps in the link. Following the steps in the link: 1. Start the computer in safe mode - It crashes to a blue screen. I have attached that screen shot. Later on it gives me the choice of either "Launch startup repair" or "Start Windows normally" 1a. Launch startup repair - It runs startup repair, but it can not fix the problem. "Startup repair can not repair this computer automatically". I can "view advanced options for system recovery and support" (see attachment and below 2-4). 1b. Start Windows normally - Does not work. It runs for a few minutes and then just takes me back to the choice of either "Launch startup repair" or "Start Windows normally". 2. Use startup repair to fix windows startup files - Program ran, but did not fix the problem. 3. Undo recent changes using system restore - Program ran, but did not fix the problem. 4. Restore your computer using a system image backup - I did not have a prior system image backup. 5. I am able to get to the command prompt. I have backed up the data from the hard drive using MS Dos commands. Can something else be done since I can get to the command prompt? Or am I at the stage of reinstalling Windows 7? Thanks! 0 comments No comments Ok. Sorry for the late reply, but I was trying all of the steps in the link. Following the steps in the link: 1.
