Merge pull request #457 from zjoasan/experimental

- Unreliable device name matching: the PR uses SPDRP_DEVICEDESC for the “name hint” check; that’s often not the same as DXGI adapter names. Prefer SPDRP_FRIENDLYNAME (or DEVPKEY_Device_FriendlyName) and handle missing values.
- Missing error checks / initialization: the code doesn’t check the return of the device-desc query and doesn’t ensure buffers are initialized → can log garbAage and make the “safety check” flaky.
- Property type/size validation: when reading the LUID device property, it should validate propSize == sizeof(LUID) and that the property type is what you expect before accepting it.
- Dead/leftover code: there’s leftover “old crap” (location, locStr, PCI bus find) that isn’t used and should be removed to avoid confusion.
- Parsing robustness: wcstoul is used without validating conversion; malformed "name,bus" can silently become bus 0.

Will fix in update. This works. :)

+# Scripts
+
+This is a collection of Powershell scripts, written during the whole driver development. PR's are welcome for improvements or other/more functions. There haven't been a focus on keeping the scripts "up to date" all the time. Which means changes that might have occurred in the modules that these scripts depend upon, haven't been corrected either. These are more ment as a framework for "tinkers" to make use of Powershell to change settings on the fly. To use these, you should be at least be comfortable with Powershell and understand Admin privilegiets, risk/reward.
+
+Anyway here is a short description of each script:
+| Script                 | Description      |
+| ---------------------- | ---------------- |
+| [silent‑install.ps1]   | Silently fetches the latest signed Virtual Display Driver from GitHub and installs it via DevCon, then tidies up the temp workspace. |
+| [modules_install.bat]  | Opens an elevated PowerShell session that installs the DisplayConfig and MonitorConfig modules so every helper script has its prerequisites. |
+| [set‑dependencies.ps1] | Verifies the exact module versions required, installs or imports them on demand, and aborts downstream execution if anything is missing. |
+| [get_disp_num.ps1]     | Returns the numeric adapter ID of the VDD screen by scanning WMI for your custom “MTT1337” monitor identifier. |
+| [changeres‑VDD.ps1]    | Hot‑swaps the virtual panel’s resolution to the width and height you pass on the command line. |
+| [refreshrate‑VDD.ps1]  | Changes the VDD monitor’s refresh rate (30‑‑500 Hz) after validating the value against a safe list. |
+| [rotate‑VDD.ps1]       | Rotates the virtual display 90°, 180°, or 270° by calling DisplayConfig with the matching rotation token. |
+| [scale‑VDD.ps1]        | Sets or resets DPI scaling on the virtual monitor, respecting Windows’ maximum allowed scale factor. |
+| [HDRswitch‑VDD.ps1]    | Flips the virtual screen between SDR (8‑bit) and HDR (10‑bit) colour modes in one click. Unsure if it works anylonger, since changes in moduels) |
+| [primary‑VDD.ps1]      | Makes the virtual display the Windows primary so you can stream or remote‑desktop from a headless rig. |
+| [toggle‑VDD.ps1]       | A one‑click PowerShell switch that first elevates itself to admin, then enables or disables your Virtual Display Driver and immediately flips Windows between Extended and Cloned desktops, perfect for streamers who need to bring a virtual monitor online or offline on demand. |
+| [winp‑VDD.ps1]         | A lightweight companion script that leaves the driver untouched and simply yo‑yos Windows between Extend and Clone modes, giving you an instant “presentation toggle” when the virtual display should stay permanently enabled. |

+<#
+.SYNOPSIS
+A comprehensive script to manage the Virtual Display Driver.
+It can install, uninstall, enable, disable, toggle, and check the status of the driver.
+
+.DESCRIPTION
+This script handles the full lifecycle of the Virtual Display Driver.
+- If no action is specified, it interactively prompts the user to select one.
+- For install/uninstall, it automatically resolves the correct version of Microsoft's DevCon utility using a nearest-build matching algorithm for maximum compatibility.
+- For enable/disable/toggle/status, it uses fast, built-in PowerShell commands.
+- It requires Administrator privileges and will self-elevate if needed by re-launching in a new window.
+- All temporary files are automatically cleaned up unless in Verbose mode for diagnostics.
+
+.PARAMETER Action
+Specifies the operation to perform. If omitted, the script will prompt for a selection.
+
+.PARAMETER DriverVersion
+Used only with the 'install' action to specify a version of the Virtual Display Driver, otherwise defaults to 'latest'.
+
+.PARAMETER Json
+If present, all output will be in JSON format for easy parsing by other programs.
+
+.PARAMETER Silent
+If present, the script will close automatically without prompting for a key press. By default, the script will pause for review before closing.
+
+.PARAMETER Verbose
+If present, prints detailed diagnostic information and prevents the temporary folder from being deleted for inspection. Provided by [CmdletBinding()].
+
+.EXAMPLE
+# --- USAGE WITHIN A POWERSHELL CONSOLE ---
+
+# Run without an action to get an interactive menu. The window will pause when finished.
+.\virtual-driver-manager.ps1
+
+# Install the driver and pause for review afterwards (default behavior).
+.\virtual-driver-manager.ps1 -Action install
+
+# Uninstall the driver and close the window automatically.
+.\virtual-driver-manager.ps1 -Action uninstall -Silent
+
+.EXAMPLE
+# --- USAGE FROM CMD.EXE OR ANOTHER PROCESS ---
+
+# Check driver status and get JSON output for automation (no pause).
+powershell.exe -ExecutionPolicy Bypass -File .\virtual-driver-manager.ps1 -Action status -Json
+
+# Enable the driver and have the window close automatically.

-# Kernel mode display-only miniport driver (KMDOD) sample
-
-The kernel mode display-only miniport driver (KMDOD) sample implements most of the device driver interfaces (DDIs) that a display-only miniport driver should provide to the Windows Display Driver Model (WDDM). The code is useful to understand how to write a miniport driver for a display-only device, or how to develop a full WDDM driver.
-
-For more info on WDDM drivers, see [Windows Display Driver Model (WDDM) Design Guide](https://docs.microsoft.com/windows-hardware/drivers/display/windows-vista-display-driver-model-design-guide).
-
-This code can also help you to understand the use and implementation of display-related DDIs. The INF file shows how to make a display miniport driver visible to other WDDM components.
-
-The sample can be installed on top of a VESA-capable graphics adapter, or on top of a graphics device that supports access to frame buffer memory through the Unified Extensible Firmware Interface (UEFI).

-The sample driver does not support the *sleep* power state. If it is placed in the sleep state, the driver will cause a system bugcheck to occur. There is no workaround available, by design.
-
-If the current display driver is not a WDDM 1.2 compliant driver, the sample driver might fail to install, with error code 43 displayed. The KMDOD driver is actually installed, but it cannot be started. The workaround for this issue is to switch to the Microsoft Basic Display Adapter Driver before installing the KMDOD sample driver, or simply to reboot your system after installing the KMDOD sample.
-
-## Installation
-
-In Microsoft Visual Studio, press **F5** to build the sample and then deploy it to a target machine. For more info, see [Deploying a Driver to a Test Computer](https://docs.microsoft.com/windows-hardware/drivers/develop/deploying-a-driver-to-a-test-computer).
-
-In some cases you might need to install the driver manually, as follows.
-
-1. Add the following files to the directory given by ...\\[x64]\\C++\\Package:
-
-    - SampleDriver.cat
-
-    - SampleDriver.inf
-
-    - SampleDriver.sys
-
-    - SampleDriver.cer
-
-1. Unless you've provided a production certificate, you should manually install the SampleDriver.cer digital certificate with the following command:
-
-    `Certutil.exe -addstore root SampleDriver.cer`
-
-1. Then enable test signing by running the following BCDEdit command:
-
-    `Bcdedit.exe -set TESTSIGNING ON`
-
-    > [!NOTE]
-    > After you change the TESTSIGNING boot configuration option, restart the computer for the change to take effect.
-
-    For more info, see [The TESTSIGNING Boot Configuration Option](https://docs.microsoft.com/windows-hardware/drivers/install/the-testsigning-boot-configuration-option).
-
-1. Manually install the driver using Device Manager, which is available from Control Panel.
-
-### ACPI-based GPUs
-
-To install the KMDOD sample driver on a GPU that is an Advanced Configuration and Power Interface (ACPI) device, add these lines to the `[MS]`, `[MS.NTamd64]`, and `[MS.NTarm]` sections of the Sampledisplay.inf file:
-
-```inf
-Text
-" Kernel mode display only sample driver " = KDODSamp_Inst, ACPI\CLS_0003&SUBCLS_0000
-" Kernel mode display only sample driver " = KDODSamp_Inst, ACPI\CLS_0003&SUBCLS_0001
-" Kernel mode display only sample driver " = KDODSamp_Inst, ACPI\CLS_0003&SUBCLS_0003
-```
-
-This new code provides generic identifiers for ACPI hardware.
-
-You can optionally delete the original lines of code within these sections of the INF file.

-# Virtual Display Driver
-based on Microsoft Indirect Display Driver Sample. This creates a virtual display in Windows that acts and functions just like a real one. It's useful for streaming, virtual reality applications, recording, headless servers, etc. The benefit over a physical display is the ability to adjust resolutions and refresh rates beyond the physical displays capabilities. For example, this would enable the ability to stream a game from your home PC using game streaming software at 240hz at 8K while owning a 60hz 1080p monitor (unrealistic, but explains the abilities well). For servers without displays, this enabled remote desktop and screen streaming to other systems as if there were a display installed.

+This project creates a _virtual monitor_ in Windows that functions just like a physical display. It is particularly useful for applications such as **streaming, virtual reality, screen recording,** and **headless servers—systems** that operate without a physical display attached. 
 
-- [Windows 10 and 11 (no HDR)](https://github.com/itsmikethetech/Virtual-Display-Driver/releases/tag/23.10.20.2)
-- [Windows 11 22H2+ (HDR)](https://github.com/itsmikethetech/Virtual-Display-Driver/releases/tag/23.12.2HDR)
- 
-## Installation
+Unlike traditional monitors, this virtual display supports custom resolutions and refresh rates beyond hardware limitations—offering greater flexibility for advanced setups. You can also use custom EDIDs to simulate or emulate existing hardware displays.
 
-1. Download the latest version from the releases page, and extract the contents to a folder.
-2. Copy `option.txt` to `C:\IddSampleDriver\option.txt` before installing the driver **(important!)**.
-3. Right click and run the *.bat file **as an Administrator** to add the driver certificate as a trusted root certificate.
-4. Don't install the inf. Open device manager, click on any device, then click on the "Action" menu and click "Add Legacy Hardware".
-5. Select "Add hardware from a list (Advanced)" and then select Display adapters
-6. Click "Have Disk..." and click the "Browse..." button. Navigate to the extracted files and select the inf file.
-7. You are done! Go to display settings to customize the resolution of the additional displays. These displays show up in Sunshine, your Oculus or VR settings, and should be able to be streamed from.
-8. You can enable/disable the display adapter to toggle the monitors.
+## ⬇️ Download Latest Version
 
-Ps. Make sure that options.txt is accesible for the system at `C:\IddSampleDriver\option.txt` or the installation will fail.
+- [Driver Installer (Windows 10/11)](https://github.com/VirtualDrivers/Virtual-Display-Driver/releases) - Check the [Releases](https://github.com/VirtualDrivers/Virtual-Display-Driver/releases) page for the latest version and release notes.
 
-## Uninstalling
-
-1. Open device manager
-2. Locate Display Adapters
-3. Right click on IddSampleDriver, choose "Uninstall device"
-4. There is a new popup window, in there click Attempt to remove driver for this device.
-
-Next instructions are for those cases where the device is removed from the system, but driver stil remains. This happens when there is a connection to the device while trying to remove the drivers. To
-remedy this, there is a a few tricks built into windows. So here goes:
-
-5. Open up a powershell terminal and input this:
-6.  ```pnputil /enum-drivers```
-6. Locate iddsampledriver.inf, there might be multiple pages of text. Make a note of the "published name", it's often unique for your system, but might look like "oem139.inf"
-7.  ```pnputil /delete-driver oem139.inf```

+> [!IMPORTANT]
+> Before using the Virtual Display Driver, ensure the following dependencies are installed:
+> - **Microsoft Visual C++ Redistributable**  
+>   If you encounter the error `vcruntime140.dll not found`, download and install the latest version from the [Microsoft Visual C++ Redistributable page](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170).
 
 
-## Background reading ##
+## 🛠️ Installation
 
-Start at the [Indirect Display Driver Model Overview](https://msdn.microsoft.com/en-us/library/windows/hardware/mt761968(v=vs.85).aspx) on MSDN.
+- Step 1: Download the Virtual Driver Control app.
+   - You can download the installer directly from the [Releases](https://github.com/VirtualDrivers/Virtual-Display-Driver/releases) page.
 
-### Code structure ###
+- Step 2: Extract to a folder and run the app
+   - Launch the VDC.
+   - Click the Install button.
 
-The sample driver code is very simplistic and does nothing more than enumerate a single monitor when its device enters the D0/started power state. The IDD runs in Session 0 without any components running in the user session, so any driver instability will not affect the stability of the system as a whole. The IDD is a user-mode only model with no support for kernel-mode components. As such, the driver is able to use any DirectX APIs in order to process the desktop image. In fact, the IddCx provides the desktop image to encode in a DirectX surface.
+- Step 3: Verify the Installation (Optional)
+   - Check if the Virtual Display Driver is correctly installed by running the following:
+   - **Device Manager:** Check "Device Manager" under "Display Adapters."
+   - **Settings:** Check display settings under system settings and see if the virtual displays show.
 
-* `Direct3DDevice` class
-    * Contains logic for enumerating the correct render GPU from DXGI and creating a D3D device.
-    * Manages the lifetime of a DXGI factory and a D3D device created for the render GPU the system is using to render frames for your indirect display device's swap-chain.
-* `SwapChainProcessor` class
-    * Processes frames for a swap-chain assigned to the monitor object on a dedicated thread.
-    * The sample code does nothing with the frames, but demonstrates a correct processing loop with error handling and notifying the OS of frame completion.
-* `IndirectDeviceContext` class
-    * Processes device callbacks from IddCx.
-    * Manages the creation and arrival of the sample monitor.
-    * Handles swap-chain arrival and departure by creating a `Direct3DDevice` and handing it off to a `SwapChainProcessor`.
+While VDC is a good and friendly way to work with VDD, you can also do a a lot manually. Like adding or removing resolutions or enable/disable 
+functions, which is done by editing vdd_settings.xml. You should be able to locate the file at the default location: 
+```C:\VirtualDisplayDriver\vdd_settings.xml ```

+# Virtual Audio Driver by MikeTheTech
+
+Welcome to the **Virtual Audio Driver by MikeTheTech**! This project provides two key drivers based on the Windows Driver Kit (WDK):
+
+- **Virtual Audio Driver** – Creates a virtual speaker output device and a virtual microphone input device.
+
+Both features in the driver are suitable for remote desktop sessions, headless configurations, streaming setups, and more. They support Windows 10 and Windows 11, including advanced audio features like Windows Sonic (Spatial Sound), Exclusive Mode, Application Priority, and volume control.

+
+## Overview
+
+A virtual audio driver set consists of:
+
+- **Virtual Audio** ("fake" speaker output)  
+  - Essential for headless servers, remote desktop streaming, testing audio in environments without physical speakers, etc.
+
+- **Virtual Microphone** ("fake" mic input)  
+  - Ideal for streaming setups, voice chat tests, combining or routing audio internally, or feeding software-generated audio to apps expecting a microphone input.
+
+By installing these drivers, you can process or forward audio without physical hardware present, making them incredibly useful for various development, testing, and media production scenarios.

+//    advanced processing or higher-fidelity capture.
+//
+// 2. If you have multiple signal processing modes (like RAW, Speech, etc.),
+//    you may add new MODE_AND_DEFAULT_FORMAT entries pointing to different
+//    subsets of the MicArrayPinSupportedDeviceFormats array.
+//
+// 3. Make sure the size of KSDATAFORMAT_WAVEFORMATEXTENSIBLE (DataFormat.FormatSize)
+//    matches the actual structure size, and that WAVEFORMATEXTENSIBLE is
+//    used properly (e.g., wValidBitsPerSample must align with wBitsPerSample).
+//
+// 4. The GUID for KSDATAFORMAT_SUBTYPE_PCM or KSDATAFORMAT_SUBTYPE_IEEE_FLOAT
+//    must be used correctly if you are advertising PCM or float formats.
+//
+// 5. KSAUDIO_SPEAKER_STEREO is a standard channel mask for 2 channels.
+//    If you have more channels (e.g., 4, 5.1, 7.1), use the appropriate
+//    speaker channel masks (e.g. KSAUDIO_SPEAKER_5POINT1).
