Win11 Creator
Using Winutil’s Win11 Creator
Winutil includes a built-in Win11 Creator tool that lets you take an official Windows 11 ISO and produce a customized, debloated version. The resulting image can remove telemetry, bypass hardware requirement checks, and enable local account setup out of the box. You can export the result as a new ISO file or write it directly to a USB drive.
Important
You need an official Windows 11 ISO from Microsoft’s website before starting. Custom, modified, or non-official ISOs are not supported. The process uses ~10–15 GB of temporary disk space, so make sure you have room.
Step 1 — Select Your Official Windows 11 ISO
- Open Winutil and go to the Win11 Creator tab.
- Click Browse and select your official Windows 11 ISO file from Microsoft (must be 4 GB or larger). Custom or modified ISOs are not supported.
- The file path and size will appear on screen once selected.
Step 2 — Mount & Verify
- Click Mount & Verify ISO.
- Winutil mounts the ISO, checks for a valid
install.wimorinstall.esd, and reads the available editions (Home, Pro, Enterprise, etc.). - Once verified, select your desired edition from the dropdown — Pro is selected by default if available.
Note
This step takes around 10–30 seconds depending on your drive speed.
Step 3 — Run the Modification
Click Run Windows ISO Modification and Creator to start the customization process. Winutil will:
App & Component Removal:
- Remove 40+ bloat apps — Clipchamp, Teams, Copilot, Dev Home, new Outlook, Bing apps, Solitaire, and more
- Delete OneDrive setup from the image
System Customization:
- Bypass hardware checks — removes TPM, Secure Boot, CPU, RAM, and storage requirement enforcement so the ISO installs on unsupported hardware
- Enable local account setup — injects an
autounattend.xmlthat skips the Microsoft account screen during OOBE - Disable BitLocker and device encryption — removes startup overhead
- Disable Chat icon — removes chat taskbar button
- Strip unused editions — keeps only your selected edition, saving 1–2 GB per removed edition
- Clean the component store — runs DISM cleanup to reclaim another 300–800 MB
Privacy & Telemetry Tweaks:
- Disable telemetry — advertising ID, tailored experiences, input personalization, speech online privacy
- Disable cloud content features — app suggestions, Microsoft Store recommendations
- Remove telemetry scheduled tasks — CEIP, Appraiser, WaaSMedic, and others
- Disable OneDrive folder backup — prevents automatic backups to cloud
- Prevent DevHome and Outlook post-setup installation
- Prevent Teams installation — blocks auto-install after OOBE
- Prevent new Outlook Mail app installation
- Disable Windows Update during OOBE — re-enabled automatically on first login
- Disable Copilot and search box suggestions
Optional: Driver Injection
- If enabled, it injects all drivers from your current system into the install.wim and boot.wim — useful for offline installations on machines with missing drivers. This is an optional checkbox in Step 3.
A live log shows progress as each step completes. This stage usually takes 10–30 minutes depending on disk speed. The WIM dismount near the end is the slowest part, so do not close Winutil while it is running.
Step 4 — Export Your Result
Once the modification is complete, choose how to save your image:
- Click Save as an ISO File.
- Choose a save location (defaults to your Desktop as
Win11_Modified_yyyyMMdd.iso). - Winutil builds a dual BIOS/UEFI bootable ISO using
oscdimg.exe.
Note
oscdimg.exe (part of the Windows ADK) is required. If it’s not found, Winutil will attempt to install it automatically via winget. If that fails, install it manually: winget install -e --id Microsoft.OSCDIMG
Typical output size: 2.5–3.5 GB (down from 5–6 GB original)
Step 5 — Clean Up (Optional)
Click Clean & Reset to delete the temporary working directory (~10–15 GB) and return the tool to its initial state, ready for a new ISO. You will be asked to confirm before anything is deleted.
What the Modified ISO Does Differently
When you install Windows 11 from your modified ISO:
- No Microsoft account required — create a local account directly during setup
- No hardware checks — installs on machines without TPM 2.0, Secure Boot, or supported CPUs
- Dark mode enabled by default
- Empty taskbar and Start Menu — no pinned apps, Chat icon removed
- Windows Update disabled during OOBE — automatically re-enabled on first login to prevent setup interruptions
- BitLocker disabled — removes startup overhead on first boot
Troubleshooting
| Problem | Fix |
|---|---|
| “install.wim not found” | Not a valid Windows 11 ISO — download a fresh one from Microsoft |
| “oscdimg.exe not found” | Run winget install -e --id Microsoft.OSCDIMG then retry |
| USB drive not showing up | Plug it in, wait a few seconds, then click Refresh |
| Modification seems stuck | The WIM dismount step is slow — wait at least 10 minutes before assuming it’s frozen |
| “Access Denied” error | Make sure Winutil is running as Administrator |

Tip
Already have a Windows 11 ISO? Skip the third-party tools and use Winutil’s built-in Win11 Creator at the top of this page.
Note
Always download Windows ISOs from official Microsoft sources or trusted tools like Rufus/UUP Dump to avoid tampered images.
Note
Newer Windows 11 ISOs may not boot correctly on older versions of Ventoy — make sure Ventoy is up to date before use. If issues persist after updating, this is a Ventoy compatibility limitation outside of Winutil’s control.
