From e6349468a1fe088dd6b1dc88206a873a3354d832 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 29 Aug 2026 21:40:46 +0000 Subject: [PATCH 1/4] Fix deployment bugs, rework hardening, add opt-in BitLocker and WinUtil steps Audit of the deployment scripts turned up several bugs that break a zero-touch run, plus a hardening baseline that both did too much in one place and too little in another. Bugs fixed: - Docs/autounattend.xml never launched WinDeploy. The first-logon script was generated as unattend-02.cmd but contained PowerShell, which cmd.exe cannot run. Made it a .ps1 and corrected the generator URL. - Harden-Windows.ps1 set SMB2=0, which disables SMB2 *and* SMB3 and breaks all file and printer sharing. Removed; replaced with SMB signing and guest-logon hardening. - Test-IntuneEnrollment and Deploy.ps1 both crashed under StrictMode ($null.Count, and $LASTEXITCODE before it is ever set). $LASTEXITCODE also leaked between steps, marking later steps as failed. - Screen lock was written to HKCU, which during deployment is the deployment account rather than the end user, and SCRNSAVE.EXE was empty so the secure lock never triggered. Now machine-wide policy. - winget installs were missing --silent, and Office used Display Level="Full", so both could show UI mid-deployment. - Windows updates without a KB number (drivers, definitions) were silently skipped by the per-KB install loop. - Seven winget font error codes were typed -1979335xxx, not -1978335xxx. - HP detection matched "*hp*", which also matches "Sharp"; HPCMSL was installed without bootstrapping NuGet/PSGallery so it stalled. - Remove-Bloat logged to %TEMP% instead of C:\WinDeploy\Logs, used a PowerShell 6+ escape in a 5.1 script, and never implemented the "prevents reinstall" its header promised. - Exit prompts now time out instead of blocking unattended runs. BitLocker previously created only a TPM protector while telling the operator to "export your BitLocker recovery key" that never existed, leaving the drive unrecoverable after a TPM clear or mainboard swap. It now asks Y/N, creates a recovery password, saves it to the operator's Documents folder and prints it on screen with a warning to store it. Added Apply-Tweaks.ps1, an opt-in step that applies a ChrisTitusTech WinUtil preset after a Y/N confirmation, and extended the hardening baseline with LSA protection, WDigest, SMB signing, LLMNR, HVCI and Defender ASR rules. Both prompts default to No after 90s, and -NonInteractive skips them entirely for the autounattend path.

New optional deployment step that applies a [ChrisTitusTech WinUtil](https://github.com/ChrisTitusTech/winutil) preset (`Standard` by default). Asks for Y/N confirmation first, since it downloads and executes a third-party script, and lists exactly what the preset changes before you answer. Runs WinUtil in its own process so a failure there cannot take down the deployment. +- BitLocker now creates a **recovery password protector** and saves it to the operator's Documents folder, then prints it on screen with a warning to store it safely. Previously only a TPM protector was created, which meant an encrypted drive was unrecoverable after a TPM clear, mainboard swap or firmware change — while the script told the operator to "export your BitLocker recovery key" that never existed. +- BitLocker is now opt-in via a Y/N prompt (`-BitLocker Ask|Yes|No`). All other hardening still applies unconditionally. +- `-NonInteractive` switch on `Deploy.ps1` and `Start.ps1`, forwarded from `autounattend.xml`, so the USB path stays zero-touch. +- Modern hardening: LSA protection (RunAsPPL), WDigest plaintext credential caching disabled, anonymous SAM/share enumeration restricted, SMB client + server signing required, insecure SMB guest logons blocked, LLMNR disabled, memory integrity (HVCI) enabled, SMBv1 feature removed, and 9 Defender Attack Surface Reduction rules. +- `Remove-Bloat.ps1` now actually implements the "prevents reinstall" its header promised, via `DisableWindowsConsumerFeatures` and related CloudContent/Store policies. + +### Fixed +- **`Docs/autounattend.xml` never launched WinDeploy.** The first-logon script was generated as `unattend-02.cmd` but contained PowerShell (`iex (irm ...)`), which `cmd.exe` cannot run. It is now a `.ps1`, and the generator URL in the header comment was corrected to `FirstLogonScriptType1=Ps1` so regenerating reproduces the fix. +- **`Harden-Windows.ps1` disabled SMB2 *and* SMB3.** The `SMB2 = 0` value under `LanmanServer\Parameters` turns off every remaining SMB version, breaking file and printer sharing. Microsoft explicitly advises against it. Removed, and replaced with SMB signing and guest-logon hardening. +- **`Test-IntuneEnrollment` crashed under `Set-StrictMode`** when the `Enrollments` key was absent: `Get-ChildItem -ErrorAction SilentlyContinue` returns `$null`, and `$null.Count` throws. +- **`Deploy.ps1` crashed under `Set-StrictMode`** on the first step, because `$LASTEXITCODE` is undefined until something sets it. It also never reset between steps, so one failing step marked every later step as failed. Now reset to `0` before each step. +- **Screen lock settings were written to the wrong profile.** `ScreenSaveActive` / `ScreenSaverIsSecure` were set under `HKCU`, which during deployment belongs to the deployment account, not the end user. Now written to the machine-wide policy hive. `SCRNSAVE.EXE` was also set to an empty string, which means Windows never starts a screen saver and the secure lock never triggers — it now points at `scrnsave.scr`. +- **Applications could show installer UI during a zero-touch deployment.** `winget install` was missing `--silent`; it now also passes `--exact` and `--disable-interactivity`. +- **Office installed interactively.** The ODT configuration used ``; now `None`. +- **Windows Updates without a KB number were skipped.** `Install-WindowsUpdate -KB $update.KB` cannot install driver and definition updates, which have no KB. Replaced with a single `Get-WindowsUpdate -Install` pass, which is also considerably faster. +- Seven WinGet font error codes were typed as `-1979335xxx` instead of `-1978335xxx`, so they could never match a real exit code. +- `Install-Drivers.ps1` matched HP with `-like "*hp*"`, which also matches manufacturers such as "Sharp". Now matched as a whole token. +- `Install-Drivers.ps1` installed `HPCMSL` without bootstrapping the NuGet provider or trusting PSGallery, so it prompted (and stalled) or failed outright. It now does the same bootstrap `Install-WindowsUpdates.ps1` already did. +- `Install-WindowsUpdates.ps1` threw under `Set-StrictMode` if `wuauserv` could not be found, instead of reporting it. +- `Remove-Bloat.ps1` logged to `%TEMP%\WinDeploy\Logs` while every other script and the README use `C:\WinDeploy\Logs`. +- `Remove-Bloat.ps1` used the `` `e `` escape (PowerShell 6+) in a script that declares `#requires -Version 5.1`, where it prints as literal garbage. +- The RMM step no longer wraps the installer in a background job that `Remove-Job -Force` could kill. `Install-RMMAgent.ps1` already launches the agent detached, so it runs inline like every other step. +- "Press Enter to exit" prompts now time out after 120 seconds instead of blocking an unattended deployment forever. + +### Changed +- Deployment scripts log failures with `Write-Warning` instead of `Write-Error`. `Write-Error` printed a full error record with category and stack trace for every non-fatal skip, which is the console noise that made a normal run look broken. `Deploy.ps1` already did this. +- `Remove-Bloat.ps1` bloatware list extended with Windows 11 24H2/25H2 in-box apps: Dev Home, the new Outlook, Edge Game Assist, Cross Device (Phone Link), Start Experiences, Meet Now and the Copilot AI provider. + +--- + ## [0.7.3] - 2026-05-01 ### Fixed diff --git a/Docs/autounattend.xml b/Docs/autounattend.xml index 68b7f9a..59cbbb5 100644 --- a/Docs/autounattend.xml +++ b/Docs/autounattend.xml @@ -1,6 +1,6 @@ - + @@ -567,8 +567,8 @@ Set-WallpaperImage -LiteralPath 'C:\Windows\Setup\Scripts\Wallpaper'; Install-Script winget-install -Force winget-install -Force - -iex (irm "https://raw.githubusercontent.com/Stensel8/WinDeploy/$((irm https://api.github.com/repos/Stensel8/WinDeploy/releases/latest).tag_name)/Scripts/Start.ps1") + +& ([scriptblock]::Create((irm "https://raw.githubusercontent.com/Stensel8/WinDeploy/$((irm https://api.github.com/repos/Stensel8/WinDeploy/releases/latest).tag_name)/Scripts/Start.ps1"))) -NonInteractive $scripts = @( @@ -814,7 +814,7 @@ $scripts = @( & 'C:\Windows\Setup\Scripts\unattend-01.ps1'; }; { - C:\Windows\Setup\Scripts\unattend-02.cmd; + & 'C:\Windows\Setup\Scripts\unattend-02.ps1'; }; { Remove-Item -LiteralPath @( diff --git a/README.md b/README.md index e1649df..c6e97ef 100644 --- a/README.md +++ b/README.md @@ -74,9 +74,17 @@ graph TD H --> I[Install RMM Agent] I --> J[Update Drivers] J --> K[Windows Hardening] - K --> L[Install Applications] + K --> K2{Enable BitLocker?} + K2 -->|Y| K3[Encrypt C: + save recovery key] + K2 -->|N / timeout| L + K3 --> L + L[Install Applications] L --> M[Remove Bloatware] - M --> N[Apply Theme] + M --> M2{Run WinUtil tweaks?} + M2 -->|Y| M3[Apply WinUtil preset] + M2 -->|N / timeout| N + M3 --> N + N[Apply Theme] N --> O[Set Hostname] O --> P[Install Windows Updates] P --> Q[Complete] @@ -84,6 +92,29 @@ graph TD `Start.ps1` ensures PowerShell 7 and WinGet are available, handles elevation, and downloads `Deploy.ps1`. `Deploy.ps1` orchestrates the deployment by downloading and executing each script in sequence. +### Interactive steps + +Two steps ask for confirmation before they run.

Read-YesNoWithTimeout used Write-Output for its "no console" message. Write-Output goes to the same stream as the return value, so the caller got @("...message...", $false) instead of $false. A 2-element array is truthy, so `if (-not $enableBitLocker)` took the wrong branch and answering No would have ENABLED BitLocker. Switched to Write-Host, which does not touch the output stream, and added a test asserting the return value is a clean [bool]. The non-interactive short-circuit also never fired. [Environment]:: UserInteractive is $true for any process in a user session, including one with redirected stdin, so the helper fell through to the polling loop and sat there for the full 90-second timeout instead of returning the default immediately. Now also checks [Console]::IsInputRedirected, and Deploy.ps1's Wait-ForExit got the same guard. While there: the countdown repainted once a second, which fills the Start.ps1 transcript with 90 redraw lines per prompt. It now repaints every 5 seconds.

Fetched the check-run annotations rather than guessing: all three are the literal prose string "XTS-AES-256" in a console message, a summary label and a docs-link key. DS187371 word-matches XTS from a list of cipher modes. The hyphens in "XTS-AES-256" form word boundaries, which is why the prose matches while the actual code (-EncryptionMethod XtsAes256) does not. The finding is wrong on the merits: XTS is the mode Microsoft recommends for BitLocker, and it is what this script configures. Rewording cannot fix it either, since any text naming the mode matches, and dropping the name would hide information the operator wants. Suppressed inline with a justification, which is DevSkim's own mechanism for this.
