I don't believe this is true anymore, I've successfully used pip with
3.5 installed in Program Files, and also just now in a test venv named
"test venv".  Do note that with installation in Program Files, you get
the benefits of the install directory being writable only to
administrators, but also the drawbacks: only administrators can use
pip to install to the global site-packages.  You can use either 'pip
--user', or create a venv in a directory writable to you and use it.
Also note that you can't use "pip.exe" to upgrade pip itself since it
can't overwrite "pip.exe" while it's in use; use 'python -m pip'
instead.

> 2) According to the Programs and Files section of the Windows Control Panel, installing Python also installs something called the Python Launcher. When I try to remove this (so I can reinstall Python in a better directory) is comes up with an error message:

The Python Launcher is a very handy tool called 'py.exe' which makes
it much easier to use more than one version of Python on a Windows
machine.  In an all users install, py.exe is installed to C:\Windows
and is thus always available on PATH, so you can invoke Python 3.5 by
calling 'py -3.5' without having to adjust your PATH.  The error
message is odd, though, would you mind trying to reproduce it and
opening a bug at bugs.python.org?

It shouldn't.  The launcher only installs 2 files, py.exe and pyw.exe
(counterpart to pythonw.exe), both in C:\Windows.

> 3) After uninstalling Python the installation directory is still there with a few files in it (possibly connected with the previous issue). Can I just delete it?

Yes, that should be fine.  I would guess it's still there due to pip
artifacts in Lib\ and Scripts\.

Hope this helps,
