(OK… after rethinking my wise-guy answer: Have you tried IOCTL_STORAGE_QUERY_PROPERTY?)
It’s practically right but slightly imperfect.
In some cases (i can said - in MANY cases) you will have not the exact serial number but its decoration in form of hexadecimal representation.
P.S. If we need this number just for some unique persistent value it’s good idea to concatenate it with Vendor and Product…
Hello tried this code and works ok on windows 8 vmware but on windows 10 vmware had to modify it a bit to work because of bsod. But on real windows 10 got bsod - page fault in non paged area. Tested it on vmware is ok but on real host this bsod do you have an idea why it is very hard to debug on real pc.

A bit difficult to see your screen from over here, but it appears to have blown up in a print. Looking at the code, this one seems most likely:
KdPrint((“SerialNumber: %s.\n”, originSerialNumber));
Well, actually, the most likely detonation site is the part where you “had to modify it a bit”.
In any case, you should load your driver symbols (.reload -f gethwid.sys) and then open the call stack window, double click on this function, open the locals and see what’s what…
If you used the debug build, windbg would be happy to show you the line of code that failed.
Yes it was the debug string indeed. When removed the first debug string : KdPrint(("Open PhysicalDrive0 success and the \n it was ok. But can you tell me why this happens with dbgprint?
