Quick Answer
The Windows 11 Media Creation Tool is Microsoft's free official app for downloading Windows 11 and building a bootable USB installer or ISO file. You need a USB drive with at least 8GB (16GB recommended) and a stable internet connection. Download it only from Microsoft's official site.
Whether you're doing a clean install on a new build, recovering a broken system, or upgrading from Windows 10, the Media Creation Tool (MCT) is Microsoft's own answer to getting Windows 11 onto a drive. It's free and official — but the tool refreshes almost every month to bundle the latest Patch Tuesday build, so behavior can shift slightly from what an older guide describes. This covers the current 2026 behavior, the errors people are actually hitting right now, and when you're better off reaching for a third-party alternative like Rufus instead.

How to Download the Windows 11 Media Creation Tool
- Go to Microsoft's official Download Windows 11 page — never download the tool from a third-party mirror or forum link, since a tampered MCT executable is a real (if rare) attack vector.
- Under "Create Windows 11 Installation Media," click Download Now.
- Run the downloaded file, named MediaCreationTool.exe. You'll need administrator permissions on the PC you're using to create the media.
Step-by-Step: Building Your Bootable USB
- Accept the license terms when the tool launches.
- On the next screen, choose "Create installation media (USB flash drive, DVD, or ISO file) for another PC." If you're upgrading the PC you're currently using in-place, choose the other option instead.
- Select your language, edition, and architecture — or leave "Use the recommended options for this PC" checked if you're building media for the same machine you're on.
- Choose USB flash drive (for a physical installer) or ISO file (if you plan to burn a DVD, mount it in a VM, or use a tool like Rufus to write the USB yourself).
- If you selected USB, plug in your drive now and select it from the list. Double-check you've picked the right drive — the tool erases it completely with only a single warning screen.
- Click Next and let the tool download and write the files. This typically takes 15–30 minutes depending on your connection speed.
- Once complete, safely eject the drive and boot the target PC from it.
Warning: Every file currently on the selected USB drive will be permanently deleted during this process. Back up anything important before you click Next.
Booting From Your New Installation Media
- Restart the target PC with the USB drive inserted.
- Enter the boot menu during startup — usually F12, F10, Esc, or Delete depending on your motherboard manufacturer.
- Select the USB drive from the boot device list. If it doesn't appear, see the USB troubleshooting section below.
- Follow the on-screen Windows Setup prompts to install or repair Windows 11.
System Requirements: USB Creation vs. the Target PC
These are two separate sets of requirements, and mixing them up is where most confusion starts.
Minimum requirements for the USB creation process itself:
- •USB drive: 8GB minimum, 16GB+ recommended (leaves headroom for drivers or recovery tools)
- •Internet connection: stable, ideally 10 Mbps or faster
- •Free disk space on the creating PC: at least 8GB, since the ISO downloads locally before being written to USB
Minimum requirements for the PC you're actually installing Windows 11 on:
- •64-bit, 1 GHz+ processor on Microsoft's supported CPU list
- •4GB RAM minimum
- •64GB storage minimum
- •TPM version 2.0
- •UEFI, Secure Boot capable
Not sure if your PC qualifies? Run Microsoft's free <strong>PC Health Check</strong> app first — it's the official Windows 11 hardware check tool and tells you exactly which requirement is blocking you, rather than leaving you to guess.
Does the Media Creation Tool Support a TPM 2.0 Bypass?
Not natively — this is the single biggest functional gap between the official tool and third-party alternatives. Unlike Rufus, the Media Creation Tool has no built-in checkbox to skip TPM, Secure Boot, or RAM checks. If your hardware doesn't meet Microsoft's requirements, MCT-created media will still show the "This PC doesn't currently meet Windows 11 system requirements" block.
That said, if you're doing a clean install from MCT-created media, you can still bypass the check manually during setup:
- Boot from your MCT-created USB and reach the Windows Setup screen.
- Press Shift + F10 to open a command prompt.
- Type regedit and press Enter.
- Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup.
- Right-click Setup, create a new key named LabConfig.
- Inside LabConfig, create DWORD (32-bit) values named BypassTPMCheck, BypassSecureBootCheck, and BypassRAMCheck, each set to 1.
- Close the command prompt and continue setup normally.
Note: This method works for a clean install only and does not bypass the minimum CPU requirement. As of 2026, this remains a widely used and functioning workaround, though it's unsupported by Microsoft and may affect future update eligibility.
For an in-place upgrade from Windows 10 (keeping your files and apps), a different registry key applies — AllowUpgradesWithUnsupportedTPMOrCPU, set under HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup. Microsoft originally published this method itself before quietly removing the official documentation page; the registry key itself continues to function as of this writing.
Does the Media Creation Tool Work for Upgrades?
Yes — when you launch MCT on the PC you want to upgrade and choose "Upgrade this PC now" instead of creating separate media, it performs an in-place upgrade that preserves your files, apps, and settings, provided your hardware passes Microsoft's checks (or you've applied the registry bypass above).
Troubleshooting Common Errors
- •Media Creation Tool not working / won't launch: Usually a corrupted download. Delete the .exe and re-download it directly from Microsoft rather than retrying the same file.
- •Stuck at 0%: Almost always a firewall, antivirus, or VPN blocking the connection to Microsoft's servers. Temporarily disable third-party security software and retry. If it's still stuck after 10+ minutes, cancel and restart the tool.
- •USB drive not recognized: Try a different USB port — ideally a rear/motherboard USB 2.0 port rather than a front-panel or USB-C hub. Reformatting the drive as FAT32 or exFAT beforehand can also resolve detection issues.
- •USB boot loop after installation: Usually a corrupted write during USB creation, or a BIOS boot-mode mismatch (UEFI vs. Legacy). Re-create the USB from scratch and confirm your BIOS boot mode matches how the USB was written.
- •Error 0x80070070: Not enough disk space on the creating PC or target drive; free up space and retry.
- •Error 0x8007025D: Corrupted or damaged installation media; re-create the USB from a fresh download.
- •Error 0xC1900101: A driver conflict during setup, usually resolved by disconnecting non-essential peripherals before booting the installer.
- •Error 0x800F0983: Has been reported alongside certain 2026 cumulative updates; check for a newer MCT build before troubleshooting further, since Microsoft has patched several instances of it at the source.
Warning: If you're seeing repeated errors after multiple attempts, don't keep reusing the same USB drive. A drive that failed once may have a partially corrupted boot sector even after reformatting — switch to a different physical drive before assuming the problem is software-side.
Rufus vs. Official Media Creation Tool
For most everyday users doing a straightforward install on supported hardware, Microsoft's own tool is genuinely the easier, safer choice. But there's one common scenario where Rufus is simply the better tool: installing Windows 11 on hardware that doesn't officially meet Microsoft's requirements.
| Category | Microsoft Media Creation Tool | Rufus |
|---|---|---|
| Speed | Moderate — downloads and writes sequentially | Fast — can write from a pre-downloaded ISO immediately, no forced re-download |
| Customization | Minimal — language, edition, USB vs. ISO only | Extensive — partition scheme, file system, persistent options, unattended install answer files |
| TPM Bypass | Not built-in; requires manual registry edit during setup | Built-in checkbox: automatically strips TPM 2.0, Secure Boot, and RAM checks at write-time |
| Ease of Use | Very simple, linear wizard, ideal for beginners | More options on screen; still straightforward but assumes slightly more technical comfort |
When to use the official Media Creation Tool:
- •You're installing on hardware that already meets Windows 11's requirements
- •You want the simplest possible path with zero extra configuration
- •You're not comfortable with registry edits or third-party tools
When to use Rufus instead:
- •Your hardware fails the TPM 2.0, Secure Boot, or RAM check and you want the bypass applied automatically rather than manually via registry edit
- •You already have a Windows 11 ISO downloaded and don't want to re-download it through MCT
- •You want to skip the Microsoft account requirement during setup, or need more granular control over partitioning
Note: Bottom line: use Microsoft's Media Creation Tool if your hardware is fully supported and you want the simplest official path. Reach for Rufus specifically when working around unsupported hardware or when you need finer control.
Windows 10 vs. Windows 11 Media Tools
The Windows 10 and Windows 11 versions of the Media Creation Tool work almost identically — same wizard, same USB-vs-ISO choice — with one meaningful difference: the Windows 11 version enforces the TPM/Secure Boot/CPU hardware check partway through, which the Windows 10 tool never did. If you want to create a Windows 11 ISO without using either tool at all, Microsoft also offers a direct ISO download page — useful for VM setups or when you just want the raw file for a tool like Rufus.
Frequently Asked Questions
Is the Windows 11 Media Creation Tool free?
Yes. It's a free official utility from Microsoft, and there's no cost to download Windows 11 through it — you'll only need a valid product key to activate the installed OS.
What's the minimum USB size for the Windows 11 Media Creation Tool?
Microsoft's official minimum is 8GB, though 16GB or larger is recommended to leave headroom for drivers, recovery tools, or unattended-install answer files.
Can I use the Media Creation Tool if my PC doesn't have TPM 2.0?
Not automatically — the tool itself doesn't offer a bypass option. You can still install by applying a manual registry edit during setup, or use Rufus, which applies the same bypass automatically when writing the USB.
Why is my Media Creation Tool stuck at 0% or not downloading?
This is almost always a firewall, antivirus, or VPN blocking the connection to Microsoft's download servers. Temporarily disable third-party security software and retry before assuming the tool itself is broken.
Does the Media Creation Tool work for upgrading from Windows 10, or only clean installs?
Both. Choosing "Upgrade this PC now" performs an in-place upgrade that keeps your files and apps, while "Create installation media for another PC" builds a clean-install USB or ISO.
