    Good day,

    Recently found out that CPU instruction "kmovd" from AVX512BW set is successfully executed on windows 10,(even on Sandy Bridge CPU).

    But same instruction with same arguments throws exception "Illegal instruction" on Windows 7 SP1 x64.

    I installed all updates(270+ at the moment), installed all VC packs x64 and x86 up to 2005 versions.

    But exception persists.

    Can this be solved by upgrading or installing some virtualization update for Windows?
