Auto Backup Pro is a portable app installed by default to the C:\AutoBackup6Pro -- the GOTD setup.exe just opens a WinRAR window that expands the files into that folder. This file backup app is intended to transfer user profiles & files to a new Windows device or a new Windows installation, though you don't have to use it for that. The developer's included a PDF User's Guide.
There is no built-in way to create a bootable USB stick or CD/DVD. Auto Backup Pro comes with a Command Line Builder, which is a separate app that lets you select what you want to happen when you run Auto Backup Pro from a command line interface [CLI], then save the results as a .cmd file you can run. So you should be able to run Auto Backup Pro itself, or using those .cmd files, from bootable USB sticks or CDs/DVDs you can create following DIY instructions online, e.g. using WinPE. Using .cmd files you've created you could also automate whatever, using anything from batch or script files to Windows Task Scheduler.
The developer offers another option on the Auto Backup web site: DIY instructions to create a bootable USB stick or disc using WinBuilder...
Mainly for techs doing on-site IT-related work [at least initially I think], there are several projects at reboot[.]pro to create portable mini versions of Windows, complete with a desktop. One of the 1st tools available [back when XP was current] is called WinBuilder -- it uses your copy of the Windows setup disc, uses universal driver packs [so Windows isn't tied to a single device like it normally is], and it includes some basic apps, along with ways to add more. This sort of thing works, & works pretty well, though it's been years since I played with it. My concern is how much trouble it might give some folks booting nowadays.
Today devices [other than phones] that can run Windows have either a legacy bios, a UEFI bios, or a sort of hybrid combining the 2. You also have secure boot and different implementations of a compatibility mode, plus no bios is perfect -- they all include design compromises, & most all include at least a couple of bugs. It's one thing to install Windows or Linux, where setup looks at the system & sets up the OS's boot loader -- it's another to try to create a USB stick or CD/DVD that will work, let alone work on more than one device.
I *think* that anyone going the WinBuilder route **might** be best off creating an ISO, setting up a Windows 10 WinPE USB stick, or a CD/DVD ISO, then using EasyBCD to add the WinBuilder created ISO to the boot menu. The Windows 10 version of WinPE is generally pretty compatible, working with all 3 kinds of bios, though some devices will *only* work with the 32 or 64 bit versions.
