The computer has rebooted from a bugcheck.  The bugcheck was: 0x000000ca (0x000000000000000b, 0xfffffa8003b2c6d0, 0×0000000000000001, 0×0000000000000000). A dump was saved in: C:WindowsMEMORY.DMP. Report Id: 050609-17612-01.

Step 3: ???

Step 4: Profit!

So far I’ve had suggestions to update my Intel Management Engine drivers, chipset drivers (which, if installed with the Setup app only updates one device – the rest need to be updated manually using Device Manager), and BIOS. All have been done with no luck. Microsoft has helpfully closed by bugs as ‘External’. Unfortunately, I can’t tell what’s going on, as the Microsoft Debug Symbol Server (http://msdl.microsoft.com/download/symbols) hasn’t been updated with RC symbols, and none are available on the Connect site yet. Oh well, life goes on.
