Yes, you can run Windows 10 from a USB drive without installing it on your computer’s internal hard drive. This allows you to test out or use Windows 10 on any computer, even ones that currently have a different operating system installed.
There are a few different ways to go about running Windows 10 from a USB drive. The main methods are:
- Using the Windows To Go feature
- Performing a full installation of Windows 10 onto the USB drive
- Creating a bootable Windows 10 installer USB
Each method has its own pros and cons, which we’ll explore in this guide. By the end, you’ll understand the differences between these options and how to set each one up properly.
Windows To Go
Windows To Go is a feature introduced in Windows 8 Enterprise that allows you to run a complete version of Windows 10 from a USB stick. With Windows To Go, you can boot and run Windows 10 on any compatible computer without having to install it locally.
How Does Windows To Go Work?
Windows To Go takes advantage of the native boot capabilities built into Windows 10. When you boot from a USB drive, Windows searches for a compatible boot configuration and loads the operating system from the external drive instead of the local hard drive.
With Windows To Go, the entire operating system is contained on the USB drive. It also saves all your settings and data back to the USB, keeping everything persistent.
This allows you to carry your personalized Windows setup with you and boot it on any compatible PC. Everything looks and feels just like it would if Windows was running locally.
Benefits of Windows To Go
There are a few notable benefits that come with using Windows To Go:
- Portability – Carry your Windows setup and files on a USB drive.
- Compatibility – Run Windows on computers with different native operating systems.
- Security – Windows To Go runs in a secure, isolated environment.
- No installation required – Windows To Go doesn’t modify local drives.
Because everything runs self-contained on the USB drive, Windows To Go leaves the host computer untouched. When you’re done, just restart and boot back into the native OS. This makes it a handy option for troubleshooting computers, running diagnostics, or accessing your preferred Windows environment anywhere.
Requirements for Windows To Go
There are some specific hardware and software requirements to use Windows To Go:
- Windows 10 Enterprise or Education edition – Home and Pro don’t support it.
- USB 3.0 drive (or USB 2.0 if booting with USB 3.0 port).
- At least 32GB capacity (64GB recommended).
- USB needs to be certified for BitLocker to enable encryption.
- Compatible computer with USB boot support enabled.
Because Windows To Go runs the entire operating system live from the drive, it needs high-performance USB sticks to maintain usability. Lower quality USB drives may have poor performance.
How to Set Up Windows To Go
Setting up Windows To Go involves a few steps:
- On a Windows 10 Enterprise computer, insert your target USB drive and open the Windows To Go startup menu.
- Choose the Drive, Edition, Language, and Keyboard options for your Windows To Go installation.
- Accept the warnings about erasing your USB drive. The process will fully format and partition the drive.
- Wait for theWindows To Go Creator tool to finish downloading Windows files and creating the bootable USB drive.
- Once complete, restart your computer and boot from the USB drive.
- The first time you boot, Windows will finish configuring itself and then take you to the desktop.
After finishing these steps, your USB drive will now have a fully portable version of Windows 10!
You can configure it just like a regular Windows installation, installing programs and changing settings as desired. All these customizations will be saved back to the USB drive.
Using Windows To Go
To use your Windows To Go drive, follow these steps whenever you want to access it:
- Insert the USB drive into a compatible computer.
- Access the boot menu (usually by pressing F12, F8, or F10 during startup).
- Select the option to boot from your USB drive.
- Windows 10 will load from the external drive.
- Log in normally once at the Windows desktop.
When shutting down, make sure to fully power down the computer. As long as the USB drive stays connected, quick restarts will boot back into Windows To Go.
Full Windows 10 USB Installation
If you don’t have access to Windows 10 Enterprise edition, you can still install Windows 10 directly onto a USB drive. This involves performing a full install of Windows rather than using the Windows To Go feature, but the end result is largely the same.
How Full USB Installation Works
During a full install, Windows gets deployed to the USB drive just like it would a local hard drive. The installer partitions, formats, and sets up the USB with a fresh copy of the operating system.
The main difference is that applications and data don’t persist across reboots. When you shutdown and unplug the USB drive, everything gets reset. Only the base operating system stays intact on the USB.
Benefits of a Full Install
Full installation has some advantages over Windows To Go:
- Works with all Windows 10 editions, including Home and Pro.
- Lets you manage drive partitions however you want.
- Allows creating multiple bootable USBs from one Windows license.
You also have full control over the install process. The tradeoff is that it doesn’t sync user settings between computers like Windows To Go. You have to reconfigure each aspect of Windows upon booting to a new machine.
Performing a Full Windows 10 Install on USB
These steps outline how to install Windows 10 directly to a USB drive:
- Use Microsoft’s Media Creation Tool to make your USB bootable.
- Boot from the USB on the computer you want to use for the install.
- When prompted, select “Custom: Install Windows Only”.
- Choose your USB drive as the destination to install Windows 10.
- Work through the rest of the installation as normal.
- Remove the USB when finished and restart your computer.
With this complete, your USB drive will now boot directly into Windows 10 whenever you connect and select it from the boot menu.
Using a USB with Full Windows 10 Installed
Since a full Windows 10 USB doesn’t save settings and data, you’ll need to configure Windows upon each boot. When using it, follow these steps:
- Boot from the USB drive on any compatible PC.
- Wait for Windows to load, then go through OOBE (the initial user setup process).
- Install any desired applications and make other configuration changes.
- Restart and select your normal boot drive when done.
The OS will reset next time you boot the USB drive. But the base Windows 10 install will remain intact on the device.
Windows 10 Installer USB
You can also create a simple Windows 10 installer USB without fully installing the operating system. This allows you to boot into the Windows setup tool for repairs or installations on other PCs.
How Installer USBs Work
The installer USB contains temporary Windows setup files rather than a complete installation. When booted, it loads a minimal Windows environment from the USB.
From there, you can access tools for troubleshooting, recovery, or deploying Windows 10 to other devices. But it doesn’t run Windows directly from the USB drive itself.
Benefits of a Windows 10 Installer USB
Installer USBs offer several notable benefits:
- Quick and easy to set up.
- Lets you boot into Windows recovery tools.
- Can reset local admin passwords.
- Enables installing Windows remotely.
You can also use an installer USB to initialize new hard drives, disk partitions, or perform fresh Windows installs. Overall, it provides a handy portable toolkit for Windows deployment, troubleshooting, and recovery.
Creating a Windows 10 Installer USB
Microsoft provides the Windows Media Creation tool to quickly turn any USB drive into a bootable installer. Just follow these steps:
- Download the Media Creation Tool from the Microsoft website.
- Run the tool, choose Create Installation Media, and select USB.
- Plug in your target USB drive with at least 5GB free space.
- Accept the prompts to download Windows and make the USB bootable.
In just a few minutes, you’ll have a handy new installer USB ready to go!
Using the Windows 10 Installer USB
To use a Windows installer USB, simply:
- Plug the USB into any compatible PC.
- Boot into the USB (typically via the boot selection menu).
- Choose your desired tool or recovery option when prompted.
- Run the selected tool, then close and restart normally.
When booted, the USB drive provides access to various Windows utilities for deployment, recovery, and troubleshooting. But it doesn’t run Windows 10 directly by itself.
Should I Install Windows 10 on a USB Drive?
Deciding whether to install Windows 10 on external storage depends on your specific needs. Consider these key factors:
- If you want a fully portable Windows environment, Windows To Go is the best choice.
- For flexible testing or installation, a full install gives you more control.
- If you just need access to Windows utilities, an installer USB is the quickest option.
- Factor in the performance limitations of USB drives compared to internal storage.
In general, Windows To Go works great for a fast, travel-ready Windows install. But it only supports Enterprise edition.
For Home or Pro users wanting to boot Windows externally, a full USB install is the way to go. Just keep in mind you’ll have to reconfigure apps and settings each time.
The installer USB works well as a utility toolkit and lets you boot into the Windows recovery environment on any PC when needed. But it doesn’t run Windows itself.
So weigh your specific needs – portability, flexibility, tools – when deciding how best to use Windows 10 from a USB drive.
