On Windows (and not under something like cygwin or msys, which have their own 
rules)? Anyway, it's not that important, the recommended approach is `python -m 
pip`, so whether using the non-recommended approach works or not doesn't really 
matter.

> On pip's issues tracker i was suggested to use `ensurepip --upgrade`.

Let's take that question back to the pip tracker. If you want the latest 
version of pip (as opposed to the bundled version) ensurepip isn't the right 
approach.

I don't know technical details but i can successfully use this command: `pip 
install --upgrade pip`.

On pip's issues tracker i was suggested to use `ensurepip --upgrade`. Therefore 
it deletes global system's pip when is ran without sudo or admin rights (when 
the current version of pip is lower then bundled).

No, you should follow the correct process and use `python -m pip`, and not use 
pip directly.

Thanks. Have not knew.

You are wrong. Windows lets me update pip via pip.

Also must notice that ensurepip also deletes the current pip before installing 
it's own. So in case of "Permission denied" error it just deletes pip (see 
https://github.com/pypa/pip/issues/9527). Should i create new issue for this?

Note the comment "to the bundled version". This command will not access the 
internet (also noted in the documentation) and so will not get a later version 
than the bundled one.

To get the latest version of pip, you need to use

/path/to/your/python -m pip install --upgrade pip

Note:

1. You must *not* use the pip executable, you must use `python -m pip`, as the 
command will be upgrading the pip executable and Windows won't let you upgrade 
an executable you are using.
2. You should use the full path to your Python, or ensure by other means that 
you are running the correct copy of Python. This command only upgrades the copy 
of pip associated with the Python interpreter you use to run the upgrade 
command.

New submission from baterflyrity :

Upgrading pip via ensurepip unfortunately doesn't do anything wealthy.
