NOTE: WORKS ON WINDOWS 95 ONLY. DO NOT APPLY TO WINDOWS NT

This is the latest and best(?) fix for the Windows 95 OOB hole that allows anyone to crash your machine. This fix works on all releases of Windows 95 (950/950a and 950b/OSR2). This patch *does* allow Netbios to work as it usually does (e.g. LAN f/p sharing) Simply double click on the .reg file included in this zip and reboot.

You may then undo whatever temporary fix you have done. To undo it, you must use regedit to remove the BSDUrgent key entirely. Please let either one of us know of any troubles.

Here is a direct quote from my source (for win95) http://www.microsoft.com/kb/articles/q158/4/74.htm

Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP

BSDUrgent = 0 or 1

If this value is 1, specifies that Microsoft TCP/IP is to treat urgent data the way some UNIX systems do (with a maximum of 1 byte of urgent data, for example). If this value is 0, it specifies that the stack is to handle urgent data as specified by RFC 1122. The default is 1.

--Note: I do not know what else this will break. I have tried several apps on my machine and they all appear to be unaffected.
