The python dizzy with clean instalation, is true !?

This will refer the python 2.7 working - but it can be extrapolated to other versions.
Many users have trouble installing python modules. The problem comes from old modules outdated or those who did not support.
I will present a few examples. I hope to come and support as necessary to remedy in time or exclusion through better solutions.
This is the main question for today: The python dizzy with clean instalation, is true !?
I don't think is a unwanted hacking of my python instalation using internet.
But I search and I saw many questions and erros over pip and Scripts folders.
I will deal just for this issue:
After I make one clean python 2.7 and all my python modules works well I used my windows to deal with some ssh software.
The next step I make it with python was to try to update with pip.
The strange think is with this files from Scripts folders:
12-Aug-16 06:41 PM 98,150 pyrsa-decrypt-bigfile.exe
12-Aug-16 06:41 PM 98,134 pyrsa-decrypt.exe
12-Aug-16 06:41 PM 98,150 pyrsa-encrypt-bigfile.exe
12-Aug-16 06:41 PM 98,134 pyrsa-encrypt.exe
12-Aug-16 06:41 PM 98,132 pyrsa-keygen.exe
12-Aug-16 06:41 PM 98,155 pyrsa-priv2pub.exe
12-Aug-16 06:41 PM 98,128 pyrsa-sign.exe
12-Aug-16 06:41 PM 98,132 pyrsa-verify.exe
and this file from same Script folder:
21-Jun-16 09:09 PM 0 python.exe
When I need to use pip I got errors.Then I try to fix with this:
pip install --upgrade ndg-httpsclient
and seem to be working now.
But I need to find from where come this file and why is this python file with:
C:\Python27\Scripts>python
Access is denied.
Maybe will be fix with a clean python instalation.
But the next step is and one of my concern is how to preserve this python instalation.
For example today the
pip update issue
come with many errors and this will be fixed.
Let's see how I fixed some of this.

First download Microsoft Visual C++ Compiler for Python 2.7.
This will fix this error:
error: Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpython27
.

If you got this error: RuntimeError: Freetype library not found
C:\Python27>Scripts\pip install freetype-py
Collecting freetype-py

100% |################################| 399kB 758kB/s
Building wheels for collected packages: freetype-py
Running setup.py bdist_wheel for freetype-py ... done
You can see also this freetype-py will not working:
C:\Python27>python.exe

>>> import freetype

from freetype.raw import *
File "C:\Python27\lib\site-packages\freetype\raw.py", line 37, in
raise RuntimeError('Freetype library not found')
RuntimeError: Freetype library not found
Also some python module has into cloud dizzy stuff.
For example the pycryptodome come with many features and working great.
Also some alternative is a bad solution.
It is hard to find a solution to the problem of leaving all these modules.
Any solutions?
