Jump to Update 3 for a quick view of problem details and cleared list.
Issues found so far
Apache(httpd) won't start, a crash happens always with "stackhash_0a9e" error
Closing Notepad++ throws an exception notification, and the process isn't closed at background
Both programs are running when crash happened.
About the windows crash
It's normal to my laptop, though I never knew the cause (I tried to find out once before, but no luck after wasting a lot of time searching, reading and playing with some debug softwares), but it works for me forcing it to shut down on blue screen and then restart, every time. In short, I believe whatever the cause of the windows crash is, it shall not be the cause of the issues in question.
Any changes to windows before it crashed?
No, I was coding and testing on my local website as usual, and no actions happened at the exact time it crashed because I was thinking on a problem. It just crashed as before, and I was ready to press the power button.
What I've done
At first I searched for the error message of starting apache and tried to figure out what's that, but then I realized it shouldn't be apache when there's no file or configuration changes.
Worried of bad disk sectors, I ran a disk check on driver of apache resides, no bad files, no bad sectors found
Guess the cause
As Issue 2 appears, I began to think it's something wrong on my windows, and if there's a difference between this crash and past crashes, I was in a hurry to back to my work and pressed down the power button too fast, I'm afraid my windows shut down before the blue screen throwing out its last line, and I suppose there's some work in the background interrupted by the shut down? What is that and how to fix it if possible?
Any advice?

I don't know what's that mean
