Description

Update the Win11 Creator guide and architecture reference for the current ISO workflow.

- Offline AppX and registry changes in install.wim
+ Setup safeguards and first-logon scripts
- 40+ AppX removals; delete OneDrive setup
+ 19 AppX removals; uninstall OneDrive at first logon
- 10–30 minutes for every modification
+ A few seconds after ISO copy without drivers; 10–20 minutes with drivers
- 512 MB EFI USB partition
+ Single FAT32 partition; split large install.wim files

The guide now states the install.esd limits for driver injection and FAT32 USB output. The architecture page limits WIM metadata checks to the driver path and identifies when setup changes run.

Issue related to PR

• Complements fix: inject Setup storage into boot.wim #5102.
• Closes [Bug Report] - Win11 Creator always outputs "Preserved the original install.wim without mounting, exporting, or modifying it." #5119

Evidence

• Before: The guide gave one 10–30 minute estimate and treated WIM dismount as part of every run.
• After: The guide separates the two driver paths and states the ESD limits. The architecture page scopes WIM checks to drivers.

📝 Summary

Summary by CodeRabbit

• Documentation
  • Updated the Windows 11 Creator guide to describe app removal and OneDrive uninstall during first logon, including the revised list of 19 removable apps.
  • Clarified when driver injection is available, how it affects processing time, and what to do when installation media contains install.esd.
  • Updated USB creation guidance for GPT drives with a single FAT32 partition, including splitting large install.wim files and saving an ISO when install.esd cannot be split.
  • Expanded setup and troubleshooting guidance for edition selection, setup fallbacks, validation, cleanup, and status logging.

Walkthrough

The Win11 Creator documentation now describes staged first-logon customization instead of offline WIM editing. It documents edition pinning, setup fallbacks, driver validation, GPT/FAT32 USB creation with WIM splitting, revised cleanup, and updated app-removal behavior.

Changes

Win11 Creator documentation

Layer / File(s)	Summary
Staged customization workflow docs/src/content/docs/code-reference/architecture.mdx	The architecture reference describes ISO copying, post-install scripting, edition pinning, setup fallbacks, and optional driver injection with WIM metadata validation.
USB export and cleanup docs/src/content/docs/code-reference/architecture.mdx, docs/src/content/docs/guides/win11creator.mdx	The documentation describes a single GPT/FAT32 partition capped at 32 GB, WIM splitting above 3.8 GB, ESD size limits, and WIM mount cleanup.
App-removal and troubleshooting guidance docs/src/content/docs/guides/win11creator.mdx	The guide updates the app-removal count and OneDrive behavior. It adds driver-injection requirements and timing, and updates missing-image and injection-stall troubleshooting.

Change: Other

Merge Risk: ⚪ Minimal · up to 1fadd

This PR only updates documentation to match the current Win11 Creator implementation (staged first-logon customization, USB export limits, driver-injection behavior). The previously flagged inaccuracy about which drivers get injected into which WIM image now appears corrected. No behavioral or code risk is introduced.

Review details

Systems and components

• observed — docs (service) was modified; 2 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in docs/src/content/docs/code-reference/architecture.mdx: The component overview splits ISO export, logging, wizard navigation, edition mapping, file copying, and oscdimg.exe handling out from the main orchestrator; USB detection and writing are documented in a separate file. The script-preparation description replaces offline WIM modification, provisioned AppX removal, and offline registry/task-file edits with setup and first-logon staging, edition pinning, and optional driver servicing.
• observed — Modified behavior in docs/src/content/docs/code-reference/architecture.mdx: The modification flow no longer mounts and modifies the selected edition of install.wim, removes provisioned AppX packages, or performs offline registry and OneDrive changes. It instead copies ISO contents and stages setup/first-logon changes, edition selection, and fallback scripts. Optional driver injection now requires install.wim (not install.esd), exports drivers, excludes stale duplicates, services boot.wim index 2 and eligible install.wim drivers, and validates WIM metadata before and after injection.
• observed — Modified behavior in docs/src/content/docs/code-reference/architecture.mdx: USB export changes from creating a 512 MB EFI partition and copying modified ISO contents to creating a single GPT/FAT32 partition capped at 32 GB. It splits install.wim when larger than 3.8 GB, rejects install.esd files at least 4 GB, and copies via robocopy. Cleanup now also dismounts open WIM mounts with discard before deleting the temporary work directory.
• observed — Modified behavior in docs/src/content/docs/code-reference/architecture.mdx: The documentation adds WIM metadata checks during driver injection and states that missing or changed required metadata stops injection before export; without injection, the original installation image is preserved and those checks are skipped. It adds edition pinning and setup-script fallback details, and changes the safety description from reversible documented changes and a dedicated log file to setup safeguards, first-logon registry changes, session/UI logging, and dismount cleanup with discard on error. The registry-tweaks description no longer characterizes the tweaks as offline.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the driver-injection description.

This section says that WinUtil injects all exported drivers into both WIM images. The current workflow injects storage drivers into boot.wim index 2 and eligible drivers into the selected install.wim.

Proposed documentation update

-**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)
+**Optional Enhancement**: When enabled, exports drivers from the running system and injects:
+- Eligible drivers into the selected `install.wim` image
+- Storage drivers into `boot.wim` index 2
