How to reinstall Windows 10 from usb without losing files?

Reinstalling Windows 10 from a USB while keeping your files safe can be a bit nerve-wracking, but it’s totally doable! I've been through this process myself. During the installation process, you’ll be asked whether you want to keep your files and apps or do a clean install. Make sure you select the option that says “Keep personal files and apps.” If you accidentally click on “Remove everything,” it’s game over for your files.

Make sure the USB drive you’re using is at least 8 GB and formatted properly (NTFS or FAT32). Also, ensure it’s not filled to the brim. A cluttered USB might fail during installation. I once tried using an old drive that was barely working, and surprise, surprise—it didn’t help. When you reinstall, it’s important to check for updates after the installation completes. If you skip this, you might miss crucial security patches or features that improve performance. Go to Settings > Update & Security > Windows Update and make sure everything’s up to date.

Depending on your hardware, you might need certain drivers after reinstalling. It’s a good idea to download those from your manufacturer’s website ahead of time and have them ready. Otherwise, you might find yourself with a device that isn’t working right after the install. If you’ve got software that requires activation (like Microsoft Office), make sure you write down your license keys before you start. Reinstalling Windows 10 from USB might cause you to lose activation, and you’ll want that key handy to get things running again.
