Yes, @StuVPS, you are right. Intel HD Graphics 2500 and 4000 use drivers from same line of drivers packages thus having the same driver version.
Check these 2 links. Both redirect to same driver package:

I made some research since you mentioned Intel HD Graphics 4600 as well. It appears that Intel HD Graphics 4600 which is bundled with 4th generation Intel Core processors use drivers from a different line of drivers packages. See: https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=3720
This further complicates the situation because we are not talking about just 1 driver release being affected but at least 2.
So don't hope for it to be fixed soon.
It may worth trying this on Intel HD Graphics 4200 and 4400 because both use same driver package as Intel HD Graphics 4600.
