Using Winutil's Win11 Creator

Winutil includes a built-in Win11 Creator tool that lets you take any official Windows 11 ISO and produce a customized, debloated version — with telemetry removed, hardware requirement checks bypassed, and local account setup enabled 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 a valid Windows 11 ISO before starting. Download one from Microsoft's official site or use UUP Dump. The process uses ~10–15 GB of temporary disk space, so make sure you have room.

---

Step 1 — Select Your ISO

1. Open Winutil and go to the Win11 Creator tab.
2. Click Browse and select your Windows 11 ISO file (must be 4 GB or larger).
3. The file path and size will appear on screen once selected.

---

Step 2 — Mount & Verify

1. Click Mount & Verify ISO.
2. Winutil mounts the ISO, checks for a valid install.wim or install.esd, and reads the available editions (Home, Pro, Enterprise, etc.).
3. 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:

• Remove 40+ bloat apps — Clipchamp, Teams, Copilot, Dev Home, new Outlook, Bing apps, Solitaire, and more
• Delete OneDrive setup from the image
• Apply registry tweaks — disables telemetry, advertising ID, tailored experiences, and cloud content features
• Bypass hardware checks — removes TPM, Secure Boot, CPU, and RAM requirement enforcement so the ISO installs on unsupported hardware
• Enable local account setup — injects an autounattend.xml that skips the Microsoft account screen during OOBE
• 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
• Remove telemetry scheduled tasks — CEIP, Appraiser, WaaSMedic, and others

A live log shows progress as each step completes. This stage takes 10–30 minutes depending on your disk speed — the WIM dismount near the end is the slowest part, so don't close Winutil while it's running.

Step 4 — Export Your Result

Once modification is complete, choose how to save your image:

{{< tabs items="Save as ISO,Write to USB" defaultIndex="0" >}}

{{< tab >}}

1. Click Save as an ISO File.
2. Choose a save location (defaults to your Desktop as Win11_Modified_yyyyMMdd.iso).
3. 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) {{< /tab >}}

{{< tab >}}

1. Click Write Directly to a USB Drive.
2. Select your USB drive from the dropdown (click Refresh if it doesn't appear).
3. Click Erase & Write to USB and confirm the warning — all data on the drive will be permanently erased.
4. Winutil formats the drive as GPT with a 512 MB EFI partition and copies the modified Windows files.

Warning

Double-check you have selected the correct drive before confirming. This operation cannot be undone.

Minimum USB size: 8 GB recommended. Writing takes 10–20 minutes. {{< /tab >}}

Step 5 — Clean Up (Optional)

Click Clean & Reset to delete the temporary working directory (~10–15 GB) and reset the tool back to its initial state, ready for a new ISO. You'll 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
• Windows Update re-enabled automatically after first login (it's paused during OOBE to prevent interruption)
• BitLocker disabled, Recall disabled, desktop shortcuts removed

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.
