I applied the latest 4.7 .Net framework update which again
broke the IIS web front end. I did manage to look in the
event view and found a number of Event 2268 errors:
Could not load ISAPI FILTERS FOR SITE DEFAULT WEB SITE.
This issue occurs when I try and patch with window updated the application falls over so then
I revert and it works then.
help would be appreciated.

I think maybe the .net framework update replace the aspnet filter with a new one and it also set the wrong physical path with double slash. You could check whether the path has
been changed to C:\Windows\Microsoft.NET\Framework64\v4.0.30319\\aspnet_filter.dll. If the path has been changed, you could just remove one slash from the path.
In addition, you could try to turn on or off the enable 32-bit application in application pool advanced setting.
This link also provide the document about how to fix 2268 issue:
