Display Driver Uninstaller (DDU)

中文

Display Driver Uninstaller（DDU）是 Windows 显卡驱动清理工具，可在升级显卡或排查安装冲突前移除残留。官网列出版本 18.1.6.1 与 .NET 4.8 要求；本文说明安全模式、备份与清理选项，帮助你从官方页面下载并谨慎使用。请先确认显卡厂商和设备情况，并阅读官网操作建议。

DDU 适合什么场景：清理驱动残留而非日常提速

DDU 用于 Windows 显示驱动的卸载与清理。厂商说明，它可以在标准卸载失败，或需要为更换/重装驱动做干净准备时，尝试清理驱动包、驱动存储区和相关文件；这类操作可能移除厂商设置或扩展，因此应当有明确的驱动问题或硬件更换计划。它不是常驻优化器，也不能保证解决所有黑屏、卡顿或安装错误。Wagnardsoft 还明确表示该工具与 NVIDIA、AMD、Intel 等硬件厂商无隶属关系。下面的资源卡片和配图是 RJ.tools 编辑制作的说明图，不是 DDU 官方图标或软件界面截图。

使用前的检查：还原点、驱动包和 BitLocker 密钥

DDU 会清理驱动残留，先保存正在处理的工作，并按 Wagnardsoft 建议创建系统还原点或备份。准备好与显卡型号、Windows 版本相符的新驱动安装包，但暂时不要启动安装程序；如果电脑启用了 BitLocker，按官方教程建议确认能够取得恢复密钥。DDU 当前页面列出 .NET Framework 4.8 和 Windows 7、8、8.1、10、11（32/64 位）要求；实际兼容情况还要结合 OEM 笔记本定制驱动和设备提示判断。不要把未知来源的清理包当成官方版本。

DDU 安装步骤：从官方页面下载并解压到本地磁盘

从 Wagnardsoft 官方 DDU 页面查看当前版本和下载说明。官方页上的下载/支持入口会跳到论坛；本次浏览遇到安全验证，因此没有下载、核验或托管安装包。下载时确认网址仍属于 Wagnardsoft，并查看页面当前版本；不要根据榜单中的旧版本号选择镜像包。

1. 打开官方发布页，确认当前显示的 DDU 版本和兼容说明。
2. 取得官方页面所指向的发布包后，先阅读随包 README；按官方教程将自解压包解到本地磁盘文件夹，不使用网络共享目录。
3. 确认 Windows 版本和 .NET Framework 4.8 要求符合设备状态，再启动解压目录中的 DDU 程序。
4. 首次启动时查看提示；厂商推荐安全模式以提高稳定性。若不熟悉安全模式，先确认如何恢复正常启动，再执行清理。

安全模式与清理选项：按显卡变更场景选择

Wagnardsoft 建议优先在安全模式运行 DDU；官方教程也允许普通模式，但建议减少后台程序并按说明处理。进入清理前，在程序中选择要处理的 GPU 厂商，核对机型和目标驱动，不要只凭旧设备名称猜测。常规清理后准备重新安装驱动时，教程把“清理并重启”作为常见选项；准备更换显卡时，可参考“清理并关机”；需要分步处理曾安装过的多个厂商驱动时，教程介绍“不重启清理”。具体按钮和选项可能随版本改变，以当前程序界面及官方教程为准。

DDU 18.1.6.1 更新说明：Windows on Arm 与扩展管理

本次核对的 Wagnardsoft 发布页标题列出 DDU 18.1.6.1。更新条目提到 Windows on Arm 下增加移除 Qualcomm Hexagon NPU 驱动的选项，并处理 Qualcomm 驱动安装器记录，以便 Snapdragon 控制面板重新安装而非只显示修复；扩展移除入口移到“专家选项”，并说明如何恢复扩展。发布说明还写明不会移除屏幕自身的扩展（例如色彩配置或 MyASUS Splendid），保留扩展所声明的组件会继续保留相应驱动。此外还包括 Lisuan 标识、统一处理厂商“添加/删除程序”记录、避免 NVIDIA 清理影响无关程序、更新笔记本/Snapdragon 帮助文本、使用后隐藏 Windows Update 按钮，以及俄语文本更新。页面日期只显示“27 Sep”，没有年份，因此不补写发布日期。

清理后的恢复思路：确认重启、驱动来源和设备厂商

清理完成后按所选操作重启或关机，再运行此前准备的显卡厂商或电脑 OEM 官方驱动安装程序。笔记本和品牌整机可能使用定制硬件 ID，应优先核对制造商页面；不要把通用显卡驱动强装到不匹配的设备。遇到启动问题时先停止重复清理，阅读 Windows 恢复提示，并按已有的还原点、备份和 BitLocker 恢复密钥处理。DDU 的作者不隶属于 GPU 厂商；使用前请评估该工具对系统驱动的影响，本页面不代表独立安全审计或对故障修复结果的保证。

常见问题（FAQ）

DDU 当前版本是多少？ 本次查看的 Wagnardsoft 页面标题列出 18.1.6.1。页面时间戳只显示 27 Sep，未写年份；安装前应再次查看官方页是否更新。

DDU 支持哪些 Windows 版本？ 当前发布页列出 Windows 7、8、8.1、10、11（32/64 位）和 .NET Framework 4.8。具体设备与 OEM 驱动的支持情况仍需核对厂商说明。

DDU clears Windows graphics-driver leftovers. This guide covers v18.1.6.1, .NET 4.8, Safe Mode, restore points and official download steps before updates.

What DDU is for: driver cleanup, not routine speed tuning

Display Driver Uninstaller removes display-driver packages and related leftovers on Windows. Wagnardsoft positions it for cases where a normal uninstall fails or a clean driver change is needed. That work can remove vendor settings or extensions, so use DDU for a defined driver issue or hardware change, not as a background optimizer. It cannot guarantee a fix for every black screen, slowdown or installer error. Wagnardsoft also says it is not affiliated with NVIDIA, AMD, Intel or other hardware vendors. The resource tile and illustrations in this guide are original RJ editorial artwork, not the DDU app icon or product screenshots.

Prepare first: restore point, driver package and BitLocker key

Save current work and follow Wagnardsoft’s advice to create a restore point or backup before removing drivers. Have the replacement package for the exact GPU and Windows version ready, but do not run its installer yet. If BitLocker is enabled, make sure you can retrieve the recovery key, as the official guide advises. The current product page lists .NET Framework 4.8 and Windows 7, 8, 8.1, 10 and 11 (32/64-bit); compatibility also depends on OEM laptop drivers and device prompts. Do not treat an unknown mirror as an official DDU package.

Install DDU: use the official page and extract to a local drive

Check the current version and download instructions on the Wagnardsoft DDU release page. Its download/support link leads to a forum; the browser session encountered a security-verification page, so no installer was downloaded, hosted or checked. Confirm that the current address remains on Wagnardsoft and verify the version shown there instead of choosing a mirror by an old ranking-sheet version.

1. Open the official release page and confirm the current DDU version and compatibility notes.
2. After obtaining the package linked by the official page, read its README and follow the official guide to extract the self-extracting archive to a local folder, not a network share.
3. Check the Windows version and .NET Framework 4.8 requirement, then launch DDU from the extracted folder.
4. Review the first-run prompt. The publisher recommends Safe Mode for stability; if you are unfamiliar with it, learn how to return to normal startup before cleaning drivers.

Safe Mode and cleanup choices: match the action to the hardware change

Wagnardsoft recommends running DDU in Safe Mode; its guide also discusses Normal Mode with additional precautions. Before cleanup, select the GPU vendor in the program and verify the device and target driver rather than relying on an old device name. For a typical cleanup before reinstalling a driver, the guide describes “Clean and restart.” It associates “Clean and shutdown” with a planned GPU swap and “Clean and do NOT restart” with staged work across multiple vendors. Button wording and options can change, so follow the current interface and publisher guidance.

DDU 18.1.6.1 release notes: Windows on Arm and extension controls

The Wagnardsoft page checked here lists DDU 18.1.6.1 in its title. Its notes describe a Windows on Arm option to remove Qualcomm Hexagon NPU drivers and handling for Qualcomm installer records so the Snapdragon Control Panel can offer a fresh install instead of Repair. Extension removal moved under Expert options with a note on restoring extensions. The page says a screen’s own extensions, such as colour profiles or MyASUS Splendid, are not removed, and drivers declared by a kept extension remain. Other listed changes include a Lisuan mark, consistent handling of vendor Add/Remove Programs entries, leaving unrelated programs alone during NVIDIA cleanup, rewritten laptop/Snapdragon help, hiding the Windows Update button after use and updated Russian text. The date shown is “27 Sep” without a year, so no release year is inferred.

Recovery after cleanup: reboot, use a matching driver and check OEM guidance

After cleanup, restart or shut down as selected, then run the GPU vendor’s or PC maker’s official driver installer you prepared. Laptops and prebuilt systems can use custom hardware IDs, so check the manufacturer’s page before forcing a generic package. If Windows does not start normally, stop repeating the cleanup, read the recovery prompt and use the restore point, backup and BitLocker key you prepared. DDU’s author is not part of a GPU vendor; review its system-level effects before use. This page is not an independent security audit and does not promise a repair outcome.

Frequently asked questions (FAQ)

What is the current DDU version? The Wagnardsoft page checked here is titled 18.1.6.1. Its date reads 27 Sep without a year; check the official page again before installing.

Which Windows versions are listed? The product page lists Windows 7, 8, 8.1, 10 and 11 (32/64-bit), plus .NET Framework 4.8. Check device and OEM driver guidance for your specific system.

Do I have to use Safe Mode? The publisher recommends it for stability and also describes Normal Mode with different precautions. If you do not know how to return to normal startup, read current Windows help before changing boot settings.

Which cleanup button should I choose? The official guide describes “Clean and restart” for a typical reinstall and “Clean and shutdown” when changing a GPU. Multi-vendor migration can require a different sequence. Confirm your hardware and the current interface first.

Can I use a package from a third-party download site? This guide did not verify any mirror package, signature or hash. Start from Wagnardsoft’s official page and check its current download instructions instead of using the ranking sheet’s older version number.
