+description: How Filip wants to work - Czech communication, discussion before coding, interactive reviews
+type: feedback
+---
+
+- Communicate in Czech (code/comments/logs stay English)
+- When Filip says "nekodujme, udelame diskusi" - he wants discussion first, not jumping to code
+- Prefers interactive HTML pages for reviews/decisions (not just markdown)
+- Likes phased approaches - start simple, evolve
+- Values colleague's field experience over theoretical best practices
+- When specs conflict, ask rather than assume
+- Filip appreciates out-of-the-box thinking (Go binaries, web platforms) but wants practical solutions
+- Don't over-engineer for 20 machines/month scale
+- Filip works on macOS, targets Windows - cross-compilation matters

+name: Technical findings from deep code analysis and research (2026-04-15)
+description: Detailed technical analysis results - Win11 compatibility issues, UCPD driver, code quality assessment, and modernization opportunities
+type: project
+---
+
+## Code quality assessment (all scripts in windows-deployment-new/scripts/)
+- Overall: solid, production-ready for Win10/11 22H2
+- 3-level registry fallback in 03-system-registry.ps1: direct write → ACL fix (SeTakeOwnershipPrivilege) → SYSTEM scheduled task
+- Proper hive handling: GC.Collect + WaitForPendingFinalizers + 500ms sleep before reg unload, always in finally block
+- Error handling: $ErrorActionPreference = "Continue", try/catch everywhere, WARN level for non-critical failures
+- Logging: every step to C:\Windows\Setup\Scripts\Deploy.log with color-coded console output
+
+## Critical issues found
+
+### 1. UCPD.sys (User Choice Protection Driver)
+- Kernel-mode driver since Feb 2024, v4.3 as of early 2026
+- Blocks direct registry writes to UserChoice for .pdf, .htm, .html etc.
+- Our HKCR approach works as system-wide fallback but isn't clean
+- Fix: disable UCPD service + scheduled task during deployment, set associations, re-enable
+- Or use SetUserFTA tool (~$20, kolbi.cz)
+
+### 2. System tray EnableAutoTray=0 broken on 24H2
+- Win11 23H2/24H2 ignores this registry key
+- Icon stream cache clearing is a workaround but not 100%
+- No reliable registry-only solution exists for 24H2
+
+### 3. OneDrive removal too aggressive
+- 03-system-registry.ps1 lines 244-273: uninstalls + deletes OneDriveSetup.exe
+- 04-default-profile.ps1 lines 240-261: removes RunOnce keys + Explorer namespace
+- Must remove these blocks entirely
+
+### 4. Edge policies incomplete
+- Currently only: HideFirstRunExperience, CreateDesktopShortcutDefault
+- Need to add: BrowserSignin=0, CopilotPageContext=0, NewTabPageContentEnabled=0, StandaloneHubsSidebarEnabled=0, ShowRecommendationsEnabled=0, DefaultBrowserSettingsCampaignEnabled=0, and ~10 more
+
+### 5. ConfigureStartPins applyOnce
+- New in 24H2 (KB5062660): {"pinnedList":[], "applyOnce": true}
+- Applies layout once, then users can customize
+- Better than our current approach (XML lock + UnlockStartLayout task)
+
+## Win10/Win11 compatibility matrix
+- All core registry keys work on both versions
+- Win11-specific keys (TaskbarAl, ShowCopilotButton, TaskbarDa, TaskbarMn) harmlessly create empty keys on Win10
+- Scripts handle version differences through graceful degradation
+
+## Config.json issues
+- desktopInfo settings (position, fontSize, color) are defined but ignored by 07-desktop-info.ps1
+- deployment.locale is not used anywhere
+- Software list has only 3 packages (TODO in SPEC)
+
+## Tools landscape (researched 2026-04-15)
+- Chris Titus WinUtil: PS-based, `irm christitus.com/win | iex`, has Win11 Creator tab
+- Win11Debloat (Raphire): got GUI in Feb 2026, configurable via Apps.json
+- Sophia Script: 150+ tweaks, most granular but slower
+- Go binary advantages: bypasses execution policy, single file, no dependencies, cross-compile from macOS
+- Charmbracelet stack (bubbletea/huh/lipgloss): best for TUI forms in Go

+
+## Key decisions made (2026-04-15 session)
+1. **BackInfo wins over custom DesktopInfo** - colleague prefers it (INI config, auto-update, centered text). Our 07-desktop-info.ps1 will be deleted.
+2. **OneDrive must NOT be removed** - current code aggressively deletes it, breaks M365. Must fix 03-system-registry.ps1 and 04-default-profile.ps1.
+3. **RDP must NOT be removed** - was in SPEC but never implemented (good). Remove from SPEC entirely.
+4. **Colleague's spec has priority** over our implementation when they overlap.
+5. **adminx9 account: no password** (changed from config-driven password), FullName = "X9.cz s.r.o."
+6. **Nextcloud not needed** - assets are in repo, only Atera MSI downloads from web.
+7. **Flash2 not integrated** - it's the old version of this tool, just for inspiration.
+8. **Atera Agent**: curl from `https://x9.servicedesk.atera.com/api/utils/agent-install/windows/?cid=31&aeid=50b72e7113e54a63ac76b96c54c7e337` then `msiexec /i setup.msi /qn`
+
+## Architecture direction (decided 2026-04-15)
+- **Go TUI launcher** (xetup.exe) - single binary, embeds PS scripts + assets
+- Charmbracelet stack: bubbletea, huh, lipgloss
+- Self-update from web (version.json check)
+- **Web platform** at xetup.x9.cz:
+  - Forgejo for git hosting + issues + CI
+  - Auto-generated documentation from spec.yaml
+  - Comments via Forgejo Issues API
+  - Landing page + download + changelog
+  - Deployment reporting dashboard (later)
+- **spec.yaml** as single source of truth for both exe and docs
+
+## What needs to happen next
+1. Create spec.yaml from all gathered specs + review
+2. Initialize Go project structure
+3. Fix PS scripts (OneDrive removal, admin password, BackInfo integration)
+4. Set up repo (GitHub initially, Forgejo later)
+5. First Go build with TUI form
+6. CI pipeline (GitHub Actions)
+7. Web landing page
+
+## Technical findings from deep analysis
+- UCPD kernel driver (since Feb 2024) blocks PDF default association via UserChoice - need to disable UCPD during deployment
+- System tray "show all icons" broken in Win11 24H2 - EnableAutoTray=0 ignored
+- Edge needs ~15 more policy keys than we currently set
+- ConfigureStartPins has new applyOnce property in 24H2
+- Current code quality is solid: 3-level registry fallback, proper hive handling with GC+finally
