Refactor core UI rendering, search matching, and service maintenance loops - #4906
Reduce repeated allocations and pipeline overhead in UI rendering, tweak application, and installed-state detection while preserving the current job layer and startup flow.
Build UI groups with generic lists and enumerate configuration properties directly.
Match application names, descriptions, and preset keys literally, without wildcard interpretation or matching the generated "Preset key: " tooltip label.
Simplify tweak/AppX search and restore categories that filtering expanded; support ItemsControl, direct StackPanel, and ScrollViewer layouts.
Consolidate repeated Windows Update service/progress loops while preserving service order and avoiding an early abort before service restart.
Check all requested package managers when both switches are supplied, while keeping detection quiet.
Preserve current main's WinGet column detection, Chocolatey-to-WinGet fallback, live toggle/error handling, service startup protection during apply and undo, ISO wizard/mount cleanup, and transcript-safe shared session logging.
Run search regression tests with actual WPF controls in an isolated Windows PowerShell 5.1 STA process, avoiding test-double type collisions.
Optional-service detection retains main's behavior: missing optional services are neutral in normal UI detection, while strict environment-report collection marks them as mismatches.
Validation
Current published head: a7d08c633d8d1c7518ae23f1fdc9607eeefea016, synchronized with main fff1c18e199daed995a30dcaac56795b79e18d44.

Full local Script Analyzer 1.20.0 invocation with lint/PSScriptAnalyser.ps1: zero errors; existing convention/test-double warnings retained without suppressions (569 warnings, 3 information diagnostics).
git diff origin/main --check: passed; no generated script or generated reference pages in the PR diff.
Full local Codex review and independent skeptical review of the complete diff: no actionable findings. Skeptic also reviewed the isolated WPF test harness.
Current-head Windows Pester and Script Analyzer: passed. 996 tests passed, zero failed or skipped. In addition, 18 search checks passed in an isolated Windows PowerShell 5.1 STA process with actual WPF loaded and Pester 5.8.0 verified. The app-search fixtures remain lightweight objects; the tweak fixtures use real WPF controls.
CodeRabbit approved the exact current head; its check passed. All review threads are resolved. Old queue findings target an implementation absent from the current PR; the existing job layer and XAML match main.
Linux cannot execute the Windows service and registry tests: an initial broader focused run had eight environment-related failures, so no passing evidence is claimed for those cases locally. Windows CI is the target-platform gate. Full interactive GUI responsiveness and destructive Windows Update/ISO operations were not manually exercised; UI search behavior is covered by regression tests, including the Windows WPF subprocess check.
Remote Codex completed its review. Its newline-escaping finding was verified as a false positive: the actual parser regex has 5 characters and 2 backslashes total, a focused check split both CRLF and LF lists correctly, and both Windows PowerShell parser tests passed. Evidence is posted in the resolved review thread. No source change was needed for that finding. GitHub reports APPROVED / CLEAN / MERGEABLE; the PR remains open for the requested merge-readiness milestone.

📝 Summary
Summary by CodeRabbit
Bug Fixes
Search treats special characters literally and matches application and tweak content without interpreting them as patterns.
Clearing a tweak search restores category visibility and expanded or collapsed state. Categories without matches are hidden.
Package manager detection reports installed only when all requested managers are available; with no manager selected, it reports not installed.
System tweak checks more accurately identify service and registry mismatches.
Improvements
Update progress is reported more consistently during Windows Update repairs and DLL registration.
Documentation
Clarified where Win11 Creator safety logs are stored and that they remain available after cleanup.
Application and tweak searches now use case-insensitive literal matching. System checks and tweak operations use explicit loops. The changes also update WPF construction, Windows Update progress reporting, related tests, and logging documentation.
Changes: Application and tweak search
Layer / File(s)
Summary
Search matching and visibility functions/private/Find-AppsByNameOrDescription.ps1, functions/private/Find-TweaksByNameOrDescription.ps1
Application search uses case-insensitive literal substring checks. Tweak search matches item text and tooltips, updates category and item visibility, tracks categories expanded by filtering, and restores visibility when the search is cleared. Search exceptions are logged at DEBUG level.
Search tests and WPF integration pester/search-filter.Tests.ps1, pester/search-filter-wpf.Tests.ps1, pester/xaml.Tests.ps1
Tests cover literal matching, supported category containers, and collapsed-state restoration. A Windows-only test runs the search tests with real WPF controls. The sync-member validation allows TweakCategoryAutoExpanded.
The check returns not-installed when no managers are requested or any requested command is missing. Tests cover combinations of requested managers and command availability.
Installed applications and applied-tweak detection functions/private/Invoke-WinUtilCurrentSystem.ps1, pester/system-helpers.Tests.ps1, pester/sanity.Tests.ps1
Application and tweak detection use explicit loops and an all-match flag. Tests cover service detection with and without -StopOnReadError. The parser test adjusts newline splitting and parse-error message construction.
Service, registry, script, and APPX processing uses foreach loops while retaining the described filtering and operation conditions.
WPF control construction
Layer / File(s)
Summary
UI elements and dialog layout functions/public/Invoke-WPFUIElements.ps1, functions/private/Show-CustomDialog.ps1
The UI builder iterates configuration properties directly and groups entries in generic lists. Dialog layout values remain unchanged.
Windows Update progress reporting
Layer / File(s)
Summary
Service, DLL, and progress updates functions/public/Invoke-WPFFixesUpdate.ps1
Service shutdown progress uses the service index. DLL progress is reported every fifth DLL and for the final DLL. Cleanup completes progress IDs 0 through 10 with the same activity label.

Review details
Systems and components
observed — functions (service) was modified; 8 changed files map to changed impact.
observed — pester (service) was modified; 6 changed files map to changed impact.
observed — docs (service) was modified; 1 changed file maps to changed impact.
Before / after behavior
observed — Modified behavior in docs/src/content/docs/code-reference/architecture.mdx: The logging description now identifies the shared timestamped session-log path and states that the log survives cleanup; the previous text referred only to the WinUtil session log and live UI status panel.
observed — Modified behavior in functions/private/Find-AppsByNameOrDescription.ps1: Search matching replaces escaped -like wildcard checks with IndexOf using OrdinalIgnoreCase for content, description, and tag. The existing category and text match conjunction still determines whether an app control is visible or collapsed.
observed — Modified behavior in functions/private/Find-TweaksByNameOrDescription.ps1: The synopsis now describes literal matching, and $SearchString no longer has an explicit optional parameter attribute. The function stops resolving $sync from global or script scope, returns when $sync or its form is null, initializes TweakCategoryAutoExpanded when absent, and selects the AppX panel only when currentTab is "AppX"; panel lookup failures or a missing panel still return.
observed — Modified behavior in functions/private/Find-TweaksByNameOrDescription.ps1: Adds Get-ItemSearchText to extract text and tooltip from the first label in a DockPanel or the first checkbox in a StackPanel; it removes the "Preset key: " tooltip prefix.

In `@functions/private/Find-TweaksByNameOrDescription.ps1`:
- Around line 34-44: Update the reset branch in Find-TweaksByNameOrDescription
so it restores each category according to its collapsed-label prefix instead of
making every item visible. Reuse the approach from Find-AppsByNameOrDescription:
detect labels starting with "+", keep those category items collapsed, and ensure
the label prefix remains consistent with item visibility.
In `@functions/private/Invoke-WinUtilCurrentSystem.ps1`:
- Around line 104-110: Update the service validation logic in
Invoke-WinUtilCurrentSystem so a missing service returned by Get-Service is
treated as a mismatch. Clear $allMatch and exit the validation loop whenever
$Service is null or its StartType differs from $tweak.StartupType; preserve the
existing matching behavior for present services with the expected startup type.
In `@functions/private/Invoke-WinUtilISO.ps1`:
- Around line 62-67: Update the timeout handling in the ISO mount flow around
Mount-DiskImage and the $mountElapsed check to dismount the mounted ISO before
raising the timeout error. Invoke the existing dismount mechanism for the target
image, then throw the same timeout message, while preserving normal mounting
behavior when the drive letter appears.
In `@functions/private/Test-WinUtilPackageManager.ps1`:
- Around line 18-24: Update the package-manager selection and validation in
Test-WinUtilPackageManager so passing both -winget and -choco cannot silently
check only winget; either reject the mutually exclusive combination or evaluate
both requested managers and return "installed" only when all requested commands
are available, while preserving the existing single-switch results.

Find-TweaksByNameOrDescription: Reset now respects collapsed category state (mirrors Find-AppsByNameOrDescription pattern). Renamed to to avoid shadowing the PowerShell automatic variable.
Invoke-WinUtilCurrentSystem: Missing service now treated as a mismatch (-not -or) instead of silently passing.
Invoke-WinUtilISO: ISO is dismounted before throwing timeout error. Restored per-workdir log file for resume/export diagnostics.
Test-WinUtilPackageManager: Both -winget and -choco switches are now evaluated when passed together.
Invoke-WPFFixesUpdate: Restored per-service PercentComplete calculation in the Stop-Service loop. Changed -ErrorAction SilentlyContinue to -ErrorAction Stop with a try/catch that aborts the repair if a service cannot be stopped.
Could the ISO log write directly to $workDir from the start? Win11ISOWorkDir is set only after success, so early failures still have no per-workdir log. Also, the test suite produces 470 passed, 1 failed. The empty-search test needs updating for the new collapsed-category behavior. Other than that it looks good, thanks for your contributions!

Both fair, thanks. The workdir log is still gated on Win11ISOWorkDir which is only set after the modify run succeeds, so I will point Log at the workDir the runspace already receives and create the folder before the first line, and since the failure path deletes workDir I will preserve the log before cleanup. For the test, the empty search case builds the category as "+ Privacy" and still expects everything visible, so I will update it to keep collapsed categories collapsed and add a "- Privacy" case for the other branch. Pushing shortly.
The log now goes to <workDir>.log beside the working directory rather than inside it, which drops the $sync["Win11ISOWorkDir"] gate entirely — %TEMP% already exists, so the first line lands before the work directory is created, and the Remove-Item -Recurse on the failure path can't reach it. Writing inside $workDir would have needed a New-Item before the first line plus a move before cleanup, and that move sits in the catch block where a throw would replace the original ISO error.
The empty-search tweak test now covers both branches — + Privacy stays collapsed, - Explorer gets restored — mirroring the app-side test. 471/471 locally and in CI, no new PSScriptAnalyzer findings, Compile.ps1 clean. Also updated the one docs line that named the old log file.
Assert the category markers after resetting the search.
The fixture uses + Privacy and - Explorer to represent collapsed and expanded states, but the test checks only visibility. A regression that changes either marker can pass. Add content assertions for both categories.
Proposed test assertions
$collapsedCategory.Label.Visibility | Should -Be ([Windows.Visibility]::Visible)
+ $collapsedCategory.Label.Content | Should -Be "+ Privacy"
$collapsedItem.Visibility | Should -Be ([Windows.Visibility]::Collapsed)
$expandedCategory.Border.Visibility | Should -Be ([Windows.Visibility]::Visible)
$expandedCategory.Label.Visibility | Should -Be ([Windows.Visibility]::Visible)
+ $expandedCategory.Label.Content | Should -Be "- Explorer"
$expandedItem.Visibility | Should -Be ([Windows.Visibility]::Visible)
