Using the MSI installer on Windows: Setting PATH and Setuptools

[cython]

Hello All,

I really hate Windows, and I have only intermittent access to Windows machines 
right now.

When I install Python 2.7 on Windows using the MSI installer, it definitely 
does not modify the PATH variable. So I modify the PATH variable myself as 
follows:

setx PATH %PATH%;C:\Python27\

Question 1: The command above requires a reboot in order to take effect, at 
least on Windows 8. How do I make it take effect immediately? Maybe if I repeat 
the same command again with 'set' instead of 'setx'? Does 'set' affect the 
whole machine, or only the current CMD.EXE session?

Question 2: python-guide.org suggests adding C:\Python27\Scripts\ to the PATH 
as well. When is that necessary or helpful? If I forget to do that and have 
problems later, how can I tell the cause of the problems?

Question 3: Does the Windows MSI installer from Python.org include Setuptools? 
python-guide.org implies that it does not include Setuptools, but I have never 
needed to manually install Setuptools, I am always able to use easy_install 
right away. Is my memory warped, or perhaps tainted by old Python installs on 
the same machine?

Question 4: If the Windows MSI installer indeed lacks Setuptools, what is the 
best way to install it from the command line in a future-proof manner (on 
Windows)? I am imagining something like this:

wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
python ez_setup.py

However, (1) wget is not a Windows command. What is the Windows command? And 
(2) is that URL the best possible URL? Or will that URL only download an old 
version, and there is a better URL for new versions?

Thank you,

Zak

PIP would definitely do the trick. Does the MSI include PIP? If it does not 
include PIP, then how can I easily install it from the command line? I am 
looking for something like this:

wget https://pip.org/install/install_pip.py
python install_pip.py

This is totally theoretical. wget doesn't work, the URL is made up, and 
install_pip.py is a fantasy of mine. ez_setup.py DOES exist for Setuptools, 
which is why I am trying to use it.

Thank you,

Zak
