Longhorn: Fewer BSODs, More RSODs
Jan Theofel writes "Windows Loghorn will present you less BSOD. Joi Ito reports that Windows Longorn will get additional ROSD (red screen of death) for 'really bad errors.' So you will get less BSOD but some new RSOD. You can find a ROSD screenshot in a virtual machine in his weblog entry."
Actually, it isn't in the registry, it's in system.ini. I haven't been able to verify whether this works, as the computer I'm on hasn't had a BSOD since I got it. I take good care of it.
