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.

Caution

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.

Note

This workflow is intended for fresh Windows installs, not in-place upgrades of an existing installation.

Step 1 — Select Your Official Windows 11 ISO

1. Open WinUtil and go to the Win11 Creator tab.
2. 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.
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:

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.xml that 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
• Pin the selected edition during setup — writes setup metadata so OEM firmware keys for a different edition do not force the installer down the wrong product-key path
• 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:

Save as ISO

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

Write to USB

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.

Danger

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.

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
“Setup has failed to validate the product key”	Recreate the ISO with the latest WinUtil. The creator now removes stale PID.txt, writes sources\ei.cfg, and pins the selected image in autounattend.xml so setup does not use an embedded OEM key for a different edition

Additional Resources

• Download official Windows 11 media from Microsoft.
• If you prefer to write a finished ISO with another tool, common choices include Rufus or Ventoy.

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.
