Ed Bott covers the situation referring to an older article at How-To Geek. Everything's basically the same except here you replace sethc.exe with a renamed cmd.exe -- you then press the Shift key 5 times to get the Command Prompt.
Both this article & the prior one spend time showing you how to get to a Command Prompt when you can't log in to Windows -- both use a Windows setup USB stick to get a Command Prompt, which you then use to move, copy, & rename files. A Win2Go drive would work, using the familiar Windows you're used to, and so will several alternative ways of booting to an OS giving you a Command Line or Prompt you can use. You can use Linux Live on a bootable USB stick, WinPE on a USB stick [which you can create after installing the Windows ADK], & there are DOS alternatives you can find using Google etc. but my favorite is to use the USB stick created with Macrium Reflect -- the USB sticks for many backup apps have the same Command Prompt option, but the Macrium Reflect USB sticks seem to successfully boot many more devices than their competition.
That said, you often have several hoops to jump through to boot to a USB stick/drive nowadays. If you're lucky there's a hotkey you can press when you 1st power on the device that will bring up a boot drive menu, and it will include the USB stick/drive -- select it & away ya go. If that's not the case, your next step is to enter the BIOS setup, preferably using another hotkey when the device is powering up. You'll likely have to research to find which hotkeys to use for your particular device -- if you're really lucky the screen will tell you when it's powering up -- and there is a [somewhat slight] chance you'll have to get to the BIOS setup using the horrible process in Windows boot menus. Once in those setup menus you want to change the boot drive order so the USB stick/drive is first -- this is the order that the BIOS uses searching attached drives looking for boot files, starting the 1st set of boot files it finds. Unfortunately Windows can remove every choice other than Windows boot mgr., making it necessary to reset the BIOS defaults. Now, your device may or may not use those default settings, so you'll want to note what they are before you do the reset, maybe taking snapshots with your phone, so you can put things back as they should be. The BIOS may keep the boot drive order you set [with the USB stick/drive 1st], or you may have to re-select it every time you (re)boot -- if it hangs on to the new boot order you may need to set it to the internal boot drive once you're done.
