Finally some decent answer , where can I get this support please?
I think you misundertood his answer due to lack of punctuation,
If you want support for Windows [comma] install Windows on a Windows computer. (non insider)
and there was nothing indecent about my answers.
You insist on getting official help from MS for something they don't support.
Besides, Insiders don't get official support on a Windows PC let alone a Mac.
