How to Run Windows 10 from USB Drive without Installing

run windows form usb

Have you ever thought about taking a copy of windows with you wherever you go so that you can run it on any computers. Now, this is not a difficult technique any more. A new feature called "Windows To Go" introduced in Windows 8 Enterprise Edition gives you the ability to install and run a portable version of Windows on a Microsoft-certifed flash drive. This feature aims to provide a more convenient way to carry their own PC environments with them, if a PC lacks your preferences/applications or that have a restricted OS, that would be a great help.

Unfortunately, The official "Windows To Go" creator only works for Windows 8 Enterprise Edition and require a Officially-certified flash drive, that's very too expensive. Instead, if you want an alternative with less overhead, I will recommend 3 utilities (Rufus and AnyWinGo), which can help you install and run Windows 10 from USB flash without installing.

What You'll Need

You only need prepare a few things to install Windows on USB drive.

1) A USB Drive

USB 3.0 and external hard drive are preferred over 2.0 flash drives as USB 3.0 and SSD is quite faster and more stable while running Windows OS. Don't use USB 2.0 as it's unusable for general computing/basic productivity and you can't run Windows on a computer smoothly. At least 32 GB of free space, but preferably 64GB. 

2) A Windows 10 ISO Image File

You can select any Editions of Windows OS if you're not planning to use official Windows To Go creator application as it only available for Windows 8 Enterprise edition. Here we suggest you choose Windows 10 Home, Professional, Education or Enterprise. Don't choose Windows 7 since it is not as portable and may have driver or activation issues.

3) AnyWinGo software

AnyWinGo is a simple software that allows you to install and run Windows from USB drive on any computers.

Part 1. Install Windows 10 to USB Drive with AnyWinGo

Part 2. Install Windows 10 to USB with CMD

Apart of AnyWinGo tool, there are also couple of other ways to install and run Windows from USB drive, among which command prompt an example, but you will need to download additional software like ImageX to deploy the Windows 8 image to your USB drive, this method is relatively complicated as it involves command line work.

Step 10. Now, for your Windows10 or Windows 8 ISO file, you can directly mount it and extract the install.wim file from the \sources\ directory of the SO to c:\wim\.

    As you can see, this method is very complex and error-prone, we don't suggest a computer novice to try it as it's full of risk. What's more, you have to download two additional software to configure the installation environment.


With some effort and risk, there are several methods you can try to install and run Windows 10 from USB flash drive. obviously, command prompt is not a good way to create a Windows To Go drive although it can, because installing Windows 10 to USB is a huge job that can't be complete in a few steps, and it is prone to errors and can easily lead to serious consequences. So, we suggest you using professional software like AnyWinGo tool, which is straightforward and easy to use.
