WhoCrashed is a totally irrelevant freeware program which tells you what Windows component just crashed your computer. It’s irrelevant because, as we all know, Windows computers never crash. As don’t Apple Macs.
Anyhoo, that said…ahem…the useful thing about this prog is the fact that it should help pinpoint the actual dodgy driver or whatever that caused the blue screen/reboot of death, thus perhaps helping you to locate an update and stop any future reoccurrences. The home version is free and works with all versions of Windows from 2000 and up.
WhoCrashed shows the drivers which have been crashing your computer with a single click. In most cases it can pinpoint the offending drivers which have been causing misery on your computer system in the past. It does post-mortem crashdump analysis and presents all gathered information in a comprehensible way.
