📋 Step-by-Step Guide (6 Steps)
Insert and Verify the Target USB Flash Drive
Plug your blank USB 3.0 flash drive into a direct USB-A or USB-C port on the computer motherboard or chassis. Open File Explorer to check that the drive mounts with a readable drive letter and at least 8 GB of capacity. Back up any leftover files immediately before proceeding.

- • Drive properties window indicates capacity equal to or greater than 8 GB
- • Plugging into a loose front-panel port or unpowered hub that may disconnect during writing
- • Leaving important personal files on the drive prior to creation
Download the Official Media Creation Tool
Open a web browser and navigate directly to the official Microsoft Windows download page. Click 'Download tool now' under the 'Create Windows installation media' section and save the executable to your desktop or Downloads folder. Do not run third-party installers from unverified sources.
- • Web browser shows completed download of 'MediaCreationTool.exe'
- • The executable icon appears clearly in the Downloads folder without file size mismatch
- • Downloading from third-party advertising links instead of official domains
- • Closing the browser before the installer download reaches 100%
Launch Setup and Accept License Terms
Right-click the downloaded setup file and select 'Run as administrator'. Click 'Yes' on the User Account Control prompt, then wait for the tool to initialize. Read and accept the software license terms when presented on screen.
- • Windows Media Creation Tool setup window displays centered on screen
- • The 'Applicable notices and license terms' screen shows active 'Accept' and 'Decline' buttons
- • Clicking 'Decline', which immediately terminates the setup wizard
- • Running the tool without administrator rights, causing permission blocks
Select Installation Media Mode
When prompted with 'What do you want to do?', select the radio button for 'Create installation media (USB flash drive, DVD, or ISO file) for another PC'. Click 'Next' to move past the initial upgrade prompt. Check the language, edition, and 64-bit architecture settings on the following screen.
- • Radio button for 'Create installation media...' is actively highlighted
- • Language, Edition (Windows 11/10), and Architecture (64-bit) show selected with 'Use recommended options' checked
- • Selecting 'Upgrade this PC now' instead of creating external installation media
- • Selecting 32-bit architecture for modern 64-bit hardware
Select the Target USB Drive and Begin Writing
Select 'USB flash drive' as the media type and click 'Next'. From the list of removable drives, pick your inserted USB drive, matching the drive letter verified in Step 1. Click 'Next' to trigger the download, file verification, and flashing process.
- • Target USB drive letter is highlighted in the drive list
- • Progress bar titled 'Downloading Windows' begins incrementing percentage values
- • Selecting the wrong removable drive letter when multiple external drives are plugged in
- • Prematurely removing the USB stick while the progress counter is active
Complete Creation and Safely Eject
Wait until the screen displays 'Your USB flash drive is ready'. Click 'Finish' to close the setup wizard and allow temporary files to clear. Open the system tray, click the 'Safely Remove Hardware' icon, and safely eject the USB drive before unplugging.
- • Final setup page showing 'Your USB flash drive is ready' with green/blue confirmation
- • System tray notification confirming 'Safe To Remove Hardware'
