I applied the Windows 7 x64 version 152258 HD Graphics Drivers to both Windows 8.1 and Server 2012. The drivers appear to work perfectly, supporting the video resolutions that I need. If there is an official release of the Windows 8.1 / Server 2012 HD Graphics Drivers for the I5-660, please let me know. For now, the Windows 7 x64 drivers appear to be fine. Thank you.

That is really good to hear!
I would like you check the following link Supported Operating Systems for Intel® Graphics Products, where you will be able to check the supported operating system for your graphics controller.
