NvwUpd - NVIDIA Driver Updater

中文 / English

A lightweight Windows application to check and update NVIDIA GPU drivers without installing NVIDIA App.

Features

• Automatic GPU Detection - Detects your NVIDIA GPU via WMI
• Official NVIDIA API - Uses the same API as nvidia.com/Download
• Driver Type Selection - Choose between Game Ready Driver and Studio Driver
• Windows Notifications - Get notified when updates are available
• Periodic Update Checks - Automatic background checking
• Modern UI - Built with WinUI 3 and Fluent Design

Requirements

• Windows 10 version 1809 or later / Windows 11
• NVIDIA GeForce GPU
• .NET 8.0 Runtime

Installation

From Release

1. Download the latest release from Releases
2. Download setup file
3. Run setup(or use portable version)

Build from Source

# Clone the repository
git clone https://github.com/zlicdt/nvwupd.git
cd nvwupd

# Build the project
dotnet build NvwUpd.csproj -c Release -p:Platform=x64

Usage

1. Launch NvwUpd
2. The app will automatically detect your GPU and current driver version
3. Click "Check for Updates" to check for the latest driver
4. Select your preferred driver type (Game Ready or Studio)
5. Click "Download & Install" to update your driver

How It Works

NvwUpd uses NVIDIA's official download API to fetch driver information:

1. GPU Detection - Uses WMI to detect installed NVIDIA GPU
2. Product Lookup - Queries NVIDIA API to get product series ID (psid) and product ID (pfid)
3. Driver Fetch - Requests driver list from processFind.aspx endpoint
4. Download - Downloads driver from NVIDIA's CDN
5. Installation - Runs silent installation with -s -noreboot flags

For technical details, see Fetch API Documentation.
