The versions of Windows called PE, aren't supported by Microsoft. Nevertheless, they aren't difficult to find, and what's more, they are very useful to have our own Windows perfectly configured, with the possibility to boot it on any PC. And now, with PeToUSB we will be able to start Windows PE from a pendrive, which will be a lot quicker than any optical reader.
Thanks to PeToUSB we'll be able to work, load and store any program and file in a Windows PE distribution, in a way that is much quicker and more stable than any CD.
It's important to remember that for any computer to boot from the USB port, it's necessary for this option to be supported and configured in the computer's BIOS.
