Windows 95 still doesn't work, even with your two patches applied.
The message is:
"A fatal exception 0E has occurred at 0137:FD512607. The current
application will be terminated.
* Press any key to terminate the current application.
* Press CTRL-ALT-DEL to restart your computer. You will
lose any unsaved information in all applications.
Press any key to continue."
I can provide debug log by email if required.
I also tested Windows 98. The first part setup correctly work, but doesn't work just after the reboot (for the first boot).
The message is very similar to Windows 95.
