BackInfo.ini: - AutoBackground=0: don't read live desktop color during deployment; Windows hasn't propagated the registry background color to the live session yet, so AutoBackground reads black - BackgroundColor=4668194: explicit COLORREF for #223B47 (was 2097152 = 0x200000 = RGB(0,0,32), near-black) 05-personalization.ps1: - Add Explorer\Accent\AccentColorMenu = 0xFF473B22 - Add Explorer\Accent\StartColorMenu = 0xFF473B22 Windows taskbar reads AccentColorMenu for its color when ColorPrevalence=1; DWM\AccentColor only controls title bars. Without these keys the taskbar shows Windows default blue (RGB 130, 232, 253 = Windows 11 "Steel" default accent). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

.SYNOPSIS
|
|
Sets system colors, wallpaper, and visual theme.
|
|
|
|
.DESCRIPTION
|
|
Applies X9.cz visual identity: dark taskbar/Start with accent color #223B47
|
|
(deep blue-gray), light app mode, no transparency. Wallpaper is set to a solid
|
|
color matching the accent. BackInfo.exe (Step 07) overwrites the wallpaper with
|
|
a live system info BMP on every logon - solid color is only the fallback.
|
|
|
|
.ITEMS
|
|
system-tema-taskbar-start-dark: SystemUsesLightTheme=0 in Themes\Personalize. Dark mode for shell (taskbar, Start menu, Action Center, notification area). Does NOT affect application windows - those stay light. Reduces eye strain in dim environments.
|
|
aplikacni-tema-light: AppsUseLightTheme=1. Application windows (File Explorer, Settings, Calculator, etc.) use white/light backgrounds. Majority of business applications (Office, browsers) also respect this and show light mode.
|
|
accent-barva-223b47-tmave-modroseda: AccentColor DWORD = 0xFF473B22 (stored as ABGR: A=FF, B=47, G=3B, R=22). The deep blue-gray #223B47 is the X9.cz brand color, also used as the solid wallpaper background.
|
|
accent-barva-na-start-a-taskbaru-ano: ColorPrevalence=1. Applies accent color to taskbar background and Start menu surface. The taskbar becomes the brand color instead of default black, creating a distinct recognizable look on X9.cz-deployed machines.
|
|
pruhlednost-vypnuta: EnableTransparency=0. Disables Aero translucency on taskbar and Start. Improves text readability on the taskbar, reduces subtle GPU usage, and looks more professional/consistent on business machines.
|
|
tapeta-jednobarevna-223b47-bez-obrazku: Wallpaper set to solid color #223B47 via SystemParametersInfo(SPI_SETDESKWALLPAPER). BackInfo.exe generates a BMP with hostname, username, OS, network info and sets it as wallpaper on every logon. Solid color = fallback only.
