how to install windows 10 to android tablet?

if sombady instaled windows 10 on android tablet?please i wil windows 10 on my tablet i this posible...

This is not currently possible. Windows 10 requires an x86/x64 processor. I don't know of any Android tablets that use an x86/x64 processor, most use ARM processors which Windows 10 does not support directly.

Windows 10 for Mobile may eventually support android devices... There has been some talk of Microsoft releasing ROM's for existing android phones and tablets, but so far there has been no official announcements.
