NVDA Portable - What are the differences when using it?

Where would I find out how to use the portable version of NVDA?

3. Getting and Setting Up NVDA
If you have not yet got a copy of NVDA, you can download it from
Go to the download section and you will find a link to download the
latest version of NVDA.
Running the file you have just downloaded will start a temporary copy
of NVDA. You will then be asked if you want to install NVDA, create a
portable copy or just continue using the temporary copy.
If you plan to always use NVDA on this computer, you will want to
choose to install NVDA. Installing NVDA will allow for additional
functionality such as automatic starting after logon, the ability to
read the Windows Logon and Windows security screens (which cannot be
done with portable and temporary copies) and creation of Start Menu
and desktop shortcuts. The installed copy is also able to create a
portable copy itself at any time.
If you want to take NVDA with you on a USB thumb drive or other
writable media, then you should choose to create a portable copy. The
portable copy also has the ability to install itself on any computer
at a later time. However, if you wish to copy NVDA onto read-only
media such as a CD, you should just copy the download package. Running
the portable version directly from read-only media is not supported at
this time.
Using the temporary copy of NVDA is also an option (e.g. for
demonstration purposes), though starting NVDA in this way each time
can become very time consuming.
3.1. Portable and Temporary Copy Restrictions
Apart from the inability to automatically start during and/or after
log-on, the portable and temporary copies of NVDA also have the
following restrictions:
• The inability to interact with applications running with
administrative privileges, unless of course NVDA itself has been run
also with these privileges (not recommended).
• The inability to read User Account Control (UAC) screens when trying
to start an application with administrative privileges.
• Windows 8 and later: the inability to support input from a touch screen.
• Windows 8 and later: the inability to provide features such as
browse mode and speaking of typed characters in Windows Store apps.
• Windows 8 and later: audio ducking is not supported.
3.3. Creating a Portable Copy
If creating a portable copy directly from the NVDA download package,
simply press the Create Portable Copy button. If you have already
closed this dialog or you are running an installed copy of NVDA,
choose the Create Portable copy menu item found under Tools in the
NVDA menu.
The Dialog that appears allows you to choose where the portable copy
should be created. This can be a directory on your hard drive or a
location on a USB thumb drive or other portable media. There is also
an option to choose whether NVDA should copy the logged on user's
current NVDA configuration for use with the newly created portable
copy. This option is only available when creating a portable copy from
an installed copy, not when creating from the download package.
Pressing Continue will create the portable copy. Once creation is
complete, a message will appear telling you it was successful. Press
OK to dismiss this dialog.

By God,
were I given all the seven heavens
with all they contain
in order that
I may disobey God
by depriving an ant
from the husk of a grain of barley,
I would not do it.
