Using a program on a flash drive?

Question

Portable Software

Good afternoon. Is it possible to somehow use programs on a USB flash drive without installing it on the computer itself? Example: I installed the Photoshop program on a USB flash drive with the necessary settings, and so on. He took out the USB flash drive, connected it to the laptop and continued to work without losing anything (if it was saved, of course).

Answer 1

you need to install / use portable versions, if they are of course,
otherwise nothing

Answer 2

It is possible to make a portable version after completing all the settings - quite difficult for a simple user.
A clean system is installed on a virtual machine, a tool for creating portable programs is installed, the system state is scanned, a program is installed - the necessary settings are made, the system is scanned again - all changes made in it are uploaded to the protable version of the program
