The header and category menu and header buttons like language and currency are the same in all views
It is just the CSS file which changes the layout.

Depending on what theme you are using - if the theme is DefaultClean the css file is
nopCommerce_4.10\Presentation\Nop.Web\Themes\DefaultClean\Content\css\styles.css

If you want to change the view files they are in
nopCommerce_4.10\Presentation\Nop.Web\Views\Shared\Components\HeaderLinks\Default.cshtml
nopCommerce_4.10\Presentation\Nop.Web\Views\Shared\Components\LanguageSelector\Default.cshtml
nopCommerce_4.10\Presentation\Nop.Web\Views\Shared\Components\CurrencySelector\Default.cshtml
etc
