There is no such option in the installation. Please take a look at the screenshot I enclosed. If in case the pictures get removed, I only have the following options:
RegisterExtensions
Tck/TK
Documentation
UtilityScripts
Test Suite
As for the commands:
C:\>python --version
Python 2.7
C:\>pytnon -m pip install blahblah
'pytnon' is not recognized as an internal or external command,
operable program or batch file.
C:\>python -m pip install blahblah
C:\Python27\python.exe: No module named pip
C:\>python -m ensurepip -Uv
C:\Python27\python.exe: No module named ensurepip
