Between cloud storage, messaging apps, and decent internet connections, I can go weeks without copying a document onto one.

I still keep several around, though, because writing them off as tiny storage devices sells them short. With the right setup, that cheap stick at the bottom of your drawer can take on jobs that are far more useful than shuttling files between computers, including a few I wouldn’t want to be without when a PC starts misbehaving.

e first jobs I give a spare USB drive. Microsoft’s Media Creation Tool can turn an 8GB or larger drive into bootable Windows installation media, giving you a way to reinstall Windows or get into the recovery tools when your installed copy refuses to boot. The process wipes the drive, so I’d dedicate one to the job rather than sacrifice whatever happens to be rattling around in your desk drawer.

Windows also has a separate Recovery Drive tool, and it serves a somewhat different purpose. Installation media gives you a general Windows installer you can use on compatible PCs, while a Recovery Drive is created from a specific computer and can include system files, updates, and manufacturer customizations from that machine. It won’t preserve your personal files, and Microsoft recommends recreating the drive periodically so it doesn’t drift too far behind the Windows setup you’re actually running.

Whichever route you choose, make the drive while your PC is behaving itself. Trying to assemble your emergency kit after Windows has already decided not to boot is spectacularly bad timing.

I like keeping a Linux live USB around for Windows emergencies because it gives me another way into a computer when Windows is having one of its catastrophic little episodes. Ubuntu, for example, can run straight from the USB, letting you explore the desktop, check hardware compatibility, troubleshoot a damaged system, or use a computer without relying on its installed OS.

Some distributions also support persistent live USBs, which can retain files, settings, and certain system changes between sessions. Persistence usually has to be configured while creating the drive, though, rather than being enabled automatically when you write the ISO.

You end up with a remarkably capable temporary PC environment that fits on a flash drive, all without repartitioning your SSD or installing another operating system.
