I too have had the random crash your system windoze update bug! Many thanks to Bill and the team at Microsoft.
You guys have one of the only google searchable posts with this issue and I would like to thank "Murray S" for supplying the below patches list responsible.
I encountered the issue two days ago doing a quick favour for a friend who hadn't patched her Toshiba Satellite Laptop since new! It sucked down 26 updates from the windowsupdate.com site and then reliably BSOD with 0xc0000018 every boot following the update.
XP Recovery didn’t work as the updates corrupted the windows system drivers. I booted up with a winternals ERD Reco disk and uninstalled the patches – Machine sprung back into life!
In my case these Critical Patches were the reason for the BSOD.
Uninstall KB893066, KB890923, KB890859 and KB893086.
