Thank you for contacting the Intel Communities.
You already have the latest driver for Intel® HD Graphics 4000.
The first digits change depending on the windows you have and the DirectX* it supports, for version you would only require to check the last four digits.
This behavior from the Intel Driver Update Utility has been seen before, but no need to worry about this, since the latest is already installed.
Additionally, I would like you to check this article that has some additional information about the numbering of versions for the drivers: http://www.intel.my/content/www/my/en/support/graphics-drivers/000005654.html
If you require any further information or support, do not hesitate to contact us back.
