Copy all the update exes into a folder
Copy this to the folder
Run - preferably from the powershell commandline

files.bat
cats.bat
regs.reg

I believe this should simply keep working even if you keep piling more updates in there.
Just make sure they're not major upgrades like dx9 - or test them separately and combine

I used the following ME updates for dev:

You'll have to check the output manually.
I noticed some files being copied to blank because the destination folder appears to be a custom folder number pulled from the registry based on the install path.
Quite clever, but would have to be fixed manually

Comments added into reg/bat to make it easier to see where things go wrong.
