Does a "windows keyboard" on bootcamp installed windows work as if on a normal PC (hotkeys etc.)?
You can choose the keyboard from within Windows 10. You should be able to choose a standard Windows keyboard when installing Windows. The rest of this answer assumes Windows 10 is already installed.

This answer was tested using Windows 10 Pro version 1909.

To add a new keyboard layout on Windows 10, use these steps:


Open Settings.
Click on Time &amp; Language.
Click on Language.
Under the "Preferred languages" section, select the current default language. In my case, this is English (United States) - US.
Click the Options button.
Under the "Keyboards" section, click the Add a keyboard button. ...
Select the new keyboard layout. In my case this is US QWERTY.


The result should appear as shown below.



Note: You may encounter the opposite, where the Windows keyboard is installed and the Apple keyboard is not.

How to choose the Windows keyboard as default.


Open Settings.
Click on Time &amp; Language.
Click on Language.
Under the "Preferred languages" section, select the Choose an input method to always use as default.
In the pulldown under "Override the default input method" section, choose English (United States) - US.


The result should appear as shown below.
