The mrt.exe bug has been fixed, but as you can see, many updates are missing. I downloaded it just to see if it's as complete as you say, but it isn't.
I know, but it's the most complete version I can develop. Except for my limitations with .NET that I can't overcome. sorry
Windows Update will continuously search for and update older GDI versions; this is normal. Nothing is missing.
If you have the ability to improve the .NETFX.CAB file that the UpdatePacks, I would be happy to share the source files used to build the UpdatePacks. Because it requires modifying INF (NETFX)files, which is too difficult for me.
As I said, I always used to swapped onepiece's netfx out for harkaz's usp4 netfx when using the update pack.
OK, sorry. It seems like nobody's interested in improving it, just using it as is. So I won't type anything further.
