MSDOS crashes because it runs in real mode most of the time - no memory
protection so it crashes like hell
Windows 95 crashes because 16 bit Windows applications can corrupt each
other and even system areas so it crashes frequently
Windows NT crashes because the device drivers which run in ring 0 are
often buggy and there just are to many things running in ring 0.
So basically the first two MS OSes were designed to crash - MSDOS was
written before hardware protection mechanisms were introduced for PCs
and Win95 would just take too long to develop and use too many resources
to be a desktop OS the way Microsoft was able to write it. The WinNT was
designed to be reliable but just somehow fails to deliver that.

Tell me if I am wrong.
