+## Win11 Creator Architecture
+
+The **Win11 Creator** is a specialized subsystem within Winutil that creates customized Windows 11 ISOs. It operates independently from the main package installation and tweak system.
+
+### Win11 Creator Components
+
+**Core Functions** (`functions/private/`):
+- `Invoke-WinUtilISO.ps1`: Main orchestrator containing all Win11 Creator functions
+  - `Invoke-WinUtilISOBrowse`: ISO file selection dialog
+  - `Invoke-WinUtilISOMountAndVerify`: Validates and mounts ISO, verifies it's official Windows 11
+  - `Invoke-WinUtilISOModify`: Launches modification in background runspace
+  - `Invoke-WinUtilISOExport`: Handles ISO and USB export
+  - `Invoke-WinUtilISOCheckExistingWork`: Recovers incomplete work sessions
+  - `Invoke-WinUtilISOCleanAndReset`: Cleans up temp directories and resets UI
+
+- `Invoke-WinUtilISOScript.ps1`: Applies modifications to mounted install.wim
+  - Removes provisioned AppX packages (40+ bloatware apps)
+  - Injects drivers (optional) from current system
+  - Removes OneDrive setup files
+  - Applies offline registry tweaks (hardware bypass, privacy, telemetry, OOBE)
+  - Deletes telemetry scheduled task definitions
+  - Pre-stages setup scripts from autounattend.xml
+  - Removes unused Windows editions
+  - Cleans component store via DISM
+
+### Win11 Creator Data Flow
+
+```
+User selects official Windows 11 ISO
+    ↓
+Invoke-WinUtilISOBrowse → OpenFileDialog, validates file size
+    ↓
+Invoke-WinUtilISOMountAndVerify
+    ├─ Mount ISO via Mount-DiskImage
+    ├─ Verify install.wim or install.esd exists
+    ├─ Check for "Windows 11" in image metadata
+    ├─ Extract available editions (Home, Pro, Enterprise, etc.)
+    └─ Store ISO path, drive letter, WIM path, image info in $sync
+    ↓
+User optionally enables Driver Injection checkbox
+    ↓
+Invoke-WinUtilISOModify (runs in background runspace)
+    ├─ Create work directory: ~WinUtil_Win11ISO_[timestamp]
+    ├─ Copy ISO contents to disk (~5-6 GB)
+    ├─ Mount install.wim at selected edition/index
+    ├─ Invoke-WinUtilISOScript:
+    │   ├─ Remove 40+ bloat AppX packages
+    │   ├─ Export and inject drivers (if enabled)
+    │   ├─ Remove OneDrive setup
+    │   ├─ Load offline registry hives
+    │   ├─ Apply 50+ registry tweaks (hardware bypass, privacy, telemetry, OOBE, etc.)
+    │   ├─ Delete telemetry scheduled task files
+    │   ├─ Pre-stage setup scripts from autounattend.xml to C:\Windows\Setup\Scripts\
+    │   └─ Unload registry hives
+    ├─ DISM /Cleanup-Image /StartComponentCleanup /ResetBase (saves 300-800 MB)
+    ├─ Dismount and save modified install.wim (~10+ minutes, slowest step)
+    ├─ Export selected edition only (removes all other editions, saves 1-2 GB each)
+    ├─ Dismount source ISO
+    └─ Report completion, enable export options
+    ↓
+Invoke-WinUtilISOExport (user chooses output)
+    ├─ Option 1: Save as ISO
+    │   ├─ Build bootable ISO via oscdimg.exe (BIOS/UEFI dual-boot)
+    │   └─ Output: Win11_Modified_[date].iso (2.5-3.5 GB)
+    │
+    └─ Option 2: Write to USB
+        ├─ Format USB as GPT
+        ├─ Create 512 MB EFI partition
+        ├─ Copy modified ISO contents
+        └─ Output: Bootable USB (minimum 8 GB)
+    ↓
+Invoke-WinUtilISOCleanAndReset (optional)
+    └─ Delete temp working directory (~10-15 GB)
+    └─ Reset UI to initial state
+```
+
+### Win11 Creator Validation & Safety
+
+**ISO Validation**:
+- Only accepts official Microsoft Windows 11 ISOs
+- Validates presence of install.wim or install.esd
+- Checks image metadata for "Windows 11" string
+- Rejects custom, modified, or non-Windows 11 ISOs
+
+**Work Session Recovery**:
+- Auto-detects incomplete work from previous sessions
+- Allows resuming Step 4 (export) without re-running Steps 1-3
+- Prevents redundant modifications
+
+**Modification Safety**:
+- All registry changes are documented in script (reversible)
+- Original ISO never modified; only working copy
+- Logged to `WinUtil_Win11ISO.log` for debugging
+- DISM handles image dismount with automatic cleanup on error
+
+### Win11 Creator Registry Tweaks
+
+The `Invoke-WinUtilISOScript` function applies **50+ offline registry tweaks**:
+
+**Hardware Bypass**:
+- TPM 2.0 check bypass
+- Secure Boot requirement bypass
+- CPU compatibility bypass
+- RAM requirement bypass
+- Storage check bypass
+
+**Privacy & Telemetry**:
+- Disable advertising ID
+- Disable tailored experiences
+- Disable input personalization
+- Disable speech online privacy
+- Disable cloud content suggestions
+- Disable app suggestion subscriptions
+- Remove CEIP, Appraiser, WaaSMedic, etc.
+
+**OOBE & Setup**:
+- Enable local account setup
+- Skip Microsoft account requirement
+- Dark mode by default
+- Empty taskbar and Start Menu
+
+**Post-Setup Installations**:
+- Prevent DevHome auto-installation
+- Prevent new Outlook Mail app installation
+- Prevent Teams auto-installation
+
+**System Features**:
+- Disable BitLocker and device encryption
+- Disable Chat icon from taskbar
+- Disable OneDrive folder backup
+- Disable Copilot
+- Disable Windows Update during OOBE (re-enabled at first login)
+
+### Driver Injection Feature
+
+**Optional Enhancement**: When enabled, exports all drivers from the running system and injects them into both:
+- `install.wim` (main OS image)
+- `boot.wim` index 2 (Windows Setup PE environment)
+
+**Use Case**: Enables offline installation on systems with missing drivers.
+
+### Disk Space Requirements
+
+- **Temporary working directory**: ~10-15 GB
+- **Original ISO**: 4-6 GB
+- **Modified ISO**: 2.5-3.5 GB
+- **Total needed**: ~25 GB for safe operation
+

 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.
