Please check and make sure you still have your Makefile.windows is still with correct encoding. I attached here my Makefile.windows. Also please change the path to remove any space. avoid "37. Nordic", do "37_Nordic" instead.

I don't see that complain of Makefile.windows missing in your first screenshot earlier. Please try on a fresh copy of the SDK.

Please check folder C:\Program Files (x86)\GNU Tools ARM Embedded to see which version of gcc you have there.

And update the file in \SDKv15.3\components\toolchain\gcc\Makefile.windows to match with your gcc version and path.

Please follow this to install pip:

Securely Download get-pip.py [1]

Run python get-pip.py. [2] This will install or upgrade pip. Additionally, it will install setuptoolsand wheel if they’re not installed already.

Do you have both Python running ? Please make sure pip was used for python 2.7 and when you execute the nrfutil, it was python 2.7
Please send a full screenshot/log of your command lines.
