To put Windows 11 on a USB drive, use Microsoft’s Media Creation Tool. Download it from the Download Windows 11 page, run it, accept the terms, choose USB flash drive, select your drive, and click Next. The tool downloads Windows 11 and makes the drive bootable. You need a USB drive of at least 8 GB, and everything on it will be erased.
The USB drive is used to install or reinstall Windows 11 on a PC. You’ll still need a valid Windows license to activate it.

- A USB flash drive with at least 8 GB of space. Back up anything on it first.
- A Windows PC with an internet connection to run the tool.
- The target PC should meet Windows 11’s requirements, including TPM 2.0 and a supported processor.

Questions about Windows 11 USB installers
Can I run Windows 11 directly from a USB drive?
Not in a supported way for home users. The USB drive is an installer; Windows runs from the PC’s internal drive after installation.
How long does it take?
Usually 20 minutes to an hour, depending on your internet speed and USB drive.
Do I need a product key?
Not to create the USB. A PC that had Windows 10 or 11 activated usually reactivates automatically.
Newer Intel PCs sometimes need an extra storage driver before Setup can see the disk, and this walkthrough on adding drivers to the USB shows how to supply it.
