v2.0.1

Version 2.0.1 — Rendering and API Modernization

This release includes a major update of the application's graphics stack, transitioning to modern DirectX and DirectWrite APIs. The primary focus is performance, stability, correct DPI handling, and long-term code maintainability.

---

✨ New Features and Improvements

1. Rendering Pipeline Modernization (Direct2D / Direct3D)

• Fully removed the legacy ID2D1HwndRenderTarget.
• Implemented modern rendering through:
  • ID3D11Device
  • DXGI Flip Model (IDXGISwapChain1, DXGI_SWAP_EFFECT_FLIP_DISCARD)
• Rendering is performed via ID2D1DeviceContext6, unlocking the latest Direct2D capabilities.
• Updated Direct2D factory to ID2D1Factory7.

Flip Model provides:

• Lower frame latency
• Improved performance
• Reduced power consumption
• Better behavior on high-DPI systems

2. DirectWrite API Update

• Replaced the legacy <dwrite.h> header with the modern <dwrite_3.h>.
• Updated interfaces:
  • IDWriteFactory → IDWriteFactory7
  • IDWriteTextFormat → IDWriteTextFormat3
• Laid the groundwork for modern typography support, including:
  • Variable fonts
  • Advanced font metadata handling
  • Improved compatibility with Windows 10 / 11

---

🔧 Bug Fixes and Code Quality

1. Compiler Warning Resolution

• Refactored COM code:
  • Switched to IID_PPV_ARGS
  • Type-safe and idiomatic handling of COM interfaces
  • Compliance with modern Microsoft and LLVM recommendations

---

🛠️ Build System

1. Build Script Updates

• Updated linker library set:
  • Added d3d11 and dxgi to support the new D3D11/DXGI pipeline.
• Completed transition to a pure LLVM toolchain (UCRT):
  • Dropped llvm-mingw
  • Using clang++, lld, llvm-rc, llvm-strip
  • Better compliance with modern C++ standards and Windows SDK

Enabled:

• C++23
• LTO (ThinLTO)
• Static linking
• Linker optimizations (/OPT:REF, /OPT:ICF)

2. Build Tools

• Ninja: 1.13.2
• CMake: 4.2.3
• LLVM: 22.1.0-rc2

v1.4.1

📝 Changelog — Windows Update Pauser

v1.4.0 → v1.4.1

---

✅ New Features

• Added restart requirement after pausing or resuming updates.
  The app now clearly indicates:
  ⚠️ Restart required to apply pause / ⚠️ Restart required to resume updates.
• Introduced a dedicated restart button (🔄 Restart Now) that performs an immediate system reboot with proper privileges.
• Implemented accurate OS version detection:
  • IsWindows10Only()
  • IsWindows11()
    Enables future OS-specific configuration logic.

---

🔒 Enhanced Security & Update Blocking

• Expanded list of disabled Windows services via registry:
  • WaaSMedicSvc (fully disabled with Start = 4 and zeroed FailureActions)
  • uhssvc (Windows 10 only)
  • Additional services (wuauserv, DoSvc, UsoSvc) are prepared but commented out for safety.
• Added extra group policies under HKLM\SOFTWARE\Policies:
  • AllowAutoWindowsUpdateDownloadOverMeteredNetwork = 0 — blocks updates on metered connections.
  • NoAutoRebootWithLoggedOnUsers = 1 — prevents automatic reboots when users are logged in.
  • AllowMUUpdateService = 0 — disables Microsoft Update.
  • PreventDeviceMetadataFromNetwork = 1 — blocks device metadata downloads.
• On resume, original FailureActions are restored for WaaSMedicSvc to ensure service stability.

---

🖥️ UI & UX Improvements

• Window is now more compact:
  • Old: 455 × 245 → New: 445 × 210
  • All UI elements slightly reduced for better visual balance.
• Improved button press animation:
  Replaced downward shift with a 98% scale-down effect ("press-in" feel).
• Added a subtle vertical gradient background for depth and modern aesthetics.
• Shadows and corner radii now scale with DPI, ensuring crisp visuals on high-resolution displays.

---

📏 High-DPI (Per-Monitor V2) Support

• Introduced global g_app.dpiScale for consistent scaling.
• Uses AdjustWindowRectExForDpi() to accurately compute window size including non-client area (borders, title bar).
• Removed legacy ApplyDpiTransform() — scaling is now handled at layout level, not render transform.
• Window is automatically centered on the active monitor with correct DPI scaling.

---

🛠 Other Improvements

• Single-instance logic: Improved detection of existing window via EnumWindows for greater reliability.
• Status panel behavior:
  • In "Restart required" mode, hover no longer changes the message (previously showed GitHub link).
  • GitHub link is only shown when no restart is pending.
• Codebase is now more modular and maintainable, with dedicated functions for OS version, DPI, and color logic.

---

💡 Note: These changes make the application more reliable, clearer about system requirements, and visually polished, especially on high-DPI and Windows 11 systems.

• Added the single-instance restriction (now you can open only single windows simultaneously).

Complete visual overhaul: Added animated diagonal gradients, glassmorphism effects, and a subtle animated "orb" background.
Introduced a glowing (glow) effect around the button on hover for a premium feel.

v1.3.17

🚀 Release v1.3.17 — "ARM64 & UCRT Era"
First native ARM64 support + Full UCRT compatibility. Built with LLVM-MinGW 20250910 (LLVM 21.1.1).

✅ Added
ARM64 Support: First-ever native build for Windows on ARM devices (Snapdragon X Elite, Surface Pro X, etc.).
UCRT Runtime Builds: All architectures (x86, x64, ARM64) now ship with both msvcrt and ucrt runtime variants.
One-Click Build Script: New build-release.bat automates compilation of all 9 binaries with proper folder structure.

🐛 Fixed
C2102 "lvalue required" Error: Fixed button hit-testing by storing GetButtonRect() result in a local variable before taking its address. (No more fighting the compiler over temporary objects!)
Missing Icons in x86/ARM64: Icons now embed correctly in all architectures by recompiling resources with --target=... for each platform. (No architecture left behind — even ARM64 gets its shiny icon now.)
Linker Error "undefined symbol: WinMain": Switched from wWinMain to WinMain(LPSTR) for MinGW compatibility.
Sure, we could’ve forced wWinMain with linker flags… but why fight the toolchain when a tiny change brings peace? 🕊️ (Also: aesthetic consistency.)

🔒 Enhanced Windows Update Lockdown
Added new registry keys to fully disable Windows Update:
SYSTEM\CurrentControlSet\Services\uhssvc → Start=4 (Disable Update Health Service)
SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate → DisableWindowsUpdateAccess=1
SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU → NoAutoUpdate=1, UseWUServer=1
SOFTWARE\Microsoft\Windows\CurrentVersion\DriverSearching → SearchOrderConfig=0

v1.0.5

2025-07-26 – v1.0.5

Important :
Update pauser switched from 4750 to 100 years bcoz that more stable :D

New features :
Added inset and height parameters for every panel
– DrawCard, DrawButton and DrawStatusPanel now accept:
• inset – inner padding (px) on all sides;
• height – exact element height (px).
Example: DrawCard(hdc, rect, 20, 50);
UI improvements
All elements share the same 8 px corner-radius and shadow.
Border color unified under BORDER_COLOR.
Button hover effect: smooth 6 px grow on mouse-over.
Technical changes
Removed GetButtonRect(); coordinates now hard-coded in PaintWindow.
Raised WINDOW_HEIGHT to 250 px for better layout.
All drawing functions refactored to use HRGN + FillRgn/FrameRgn.

v1.0.1

Fixed :

Correct window scaling on high-DPI monitors.
Previously the UI elements scaled properly, but the window’s physical size remained fixed at 465 × 240 px, causing the content to look oversized.
The window now calculates its size via MulDiv(base_size, DPI, 96) before creation, ensuring the correct physical pixel dimensions on any DPI setting.

v1.0.0
