UPDATE: Willl's friend noticed that "execution" is spelled "exectuion". Either this is a hoax, or they haven't spellchecked Longhorn. Can anyone out there confirm this RSOD?
UPDATE 2: It appears that Michael is an employee of Microsoft. He also informs us that the RSOD is not an "upgrade". Longhorn still has BSOD. RSOD is for really bad errors.
