This has not yet been reported to Microsoft.


I would imagine that this would affect any XP machine. I am not sure about other versions. The problem is when you lock down your system to Guide lines such as NIST's, you remove the Everone group from virtually all NTFS permissions on the C drive. Apparently when Microsoft tested this patch they did not test it with the recommended hardening in place that may companies are using. Where you might see this on a standalone machine is that your dialup and pptp connection will have dissappeared.
