In this case the both processors in question belong to the 2nd Generation Intel® Core™ Processors with Intel® HD Graphics 3000 meaning that generations is not supported with Windows 10, here you can check the Supported Operating Systems Graphics Drivers — Supported Operating Systems.
It's possible to install Windows 10 but it comes to the drivers there won't be any driver compatible for that Graphics version.
The WiDi technology that operates with Windows 7, Windows 8 and Windows 8.1, here you can check the system requirements for Intel® WiDi Support Knowledge Base.
Intel really do not understand do they there is thousands of people who have these gen of processor and graphic's.
Right i am going to explain this in as much detail as i can.
within Windows 7,8,8.1 this where poor OS for Intel hardware and the processor maxed out in multiply operations.
Memory out of 6 GB -3 GB
This OS is a completely different matter the processor what is 2.30 GHZ use's 1.10 Ghz at a push so there is 1.20 GHZ available.
Memory out of 6 GB's 1.5 GB's.
So to me i really do not understand why Intel think this generation should not be supported i would understand anything under 1.7 GHZ not to be supported in these generation's of processor's and graphic's we are talking about.
Wireless display will surely be missed by those people who where using this feature in the other version of windows.
Can't Intel reconsider this decision even if it was only for a year.
