DDU (Display Driver Uninstaller): Official Download and Safe Use

Short answer: Display Driver Uninstaller (DDU) is a free tool by Wagnard (Ghislain Harvey) of Wagnardsoft. It removes NVIDIA, AMD, Intel and other graphics drivers along with their leftovers. The current version is 18.1.6.0, released September 15, 2026. The developer names wagnardsoft.com as DDU’s official download location and publishes SHA-256 hashes for both builds. His recommended procedure: disconnect from the internet or block Windows Update, run DDU in Safe Mode, clean, reboot, then install the new driver. He also says DDU should not be used every time you install a new driver.

Where to download DDU

DDU’s official download location is www.wagnardsoft.com. The developer states this in the “Official Display Driver Uninstaller (DDU) Distribution Policy” in his 18.1.6.0 release post. The policy says other trusted mirrors may host DDU only if they credit the developer accurately and don’t imply ownership, and that unauthorized redistribution is prohibited.

Guru3D hosts DDU too, and its download page calls Guru3D “an official download partner.” That claim comes from Guru3D, not from the developer’s policy text, which names only wagnardsoft.com. Whichever site you use, compare the file’s hash with the one the developer publishes below.

We link to the developer’s page and never rehost the file. Wagnardsoft’s release post is the page that carries the official download links and hashes.

DDU 18.1.6.0 files and SHA-256

We downloaded both files from download.wagnardsoft.com on September 26, 2026. Both hashes matched, and both files carry a valid Authenticode signature from Wagnardsoft (Quebec, Canada), issued by Sectigo. To check your copy in PowerShell:

Get-FileHash ".\DDU v18.1.6.0.exe" -Algorithm SHA256

Then right-click the file, open Properties > Digital Signatures, and confirm the signer is Wagnardsoft. Our DDU app page keeps the current hashes, and our guide to fake download sites explains why the signer’s name matters more than the presence of a signature.

What’s new in 18.1.6.0

From the developer’s changelog:

• Qualcomm Adreno (Snapdragon X) support on Windows on Arm, with an option for the Snapdragon Control Panel. ARM64 PCs are now shown as ARM64.
• NVIDIA cleanup prepared for the upcoming RTX Spark.
• On Intel and Qualcomm laptops, the PC maker’s driver extensions are now kept by default. The developer says the generic driver does not restore them and the GPU may not start without them (Code 31). An option still removes them.
• The camera driver is kept when the camera sits under the GPU (Intel Lunar Lake, Snapdragon).
• Windows’ basic display driver is re-enabled before cleaning. With it off, removing the graphics driver gave a black screen.
• Safe Mode no longer fails on the first try after an older DDU.
• The Options window now has one tab per GPU vendor.

Requirements: Windows 7 up to Windows 11, Microsoft .NET Framework 4.8 or higher. The release post lists NVIDIA, AMD, Intel, Qualcomm and Lisuan GPUs, plus basic Realtek audio driver cleanup.

When to use DDU

The developer lists two situations:

• You have a problem uninstalling or installing a graphics driver.
• You are switching GPU brands, for example from AMD to NVIDIA.

His product page adds that some users report DDU fixes problems installing an older or newer driver. The DDU guide also covers PCs that had both AMD and NVIDIA cards in the same Windows install. In that case, the guide recommends removing both vendors’ drivers to avoid conflicts.

When not to use DDU

• For routine driver updates. The developer: “DDU should not be used every time you install a new driver unless you know what you are doing.” Try the driver’s own clean-install option first. NVIDIA’s installer has “Perform a clean installation” under Custom (Advanced).
• From a network drive or OneDrive folder. The developer says DDU will not work there. Put it on a local drive.
• Without your BitLocker recovery key. If BitLocker is on, Windows may ask for the recovery key when you reboot into Safe Mode.
• If you only know your Windows Hello PIN. The developer warns that on Windows 11 24H2 your PIN may not work in Safe Mode. Make sure you know your account password and have used it at least once in normal mode.
• On a laptop, removing the maker’s extensions without a reason. In 18.1.6.0 they are kept by default for a reason. Leave that default alone unless you have the laptop maker’s driver package ready.

Before you start

1. Back up anything important, and create a system restore point. The developer recommends both.
2. Download the new driver first from NVIDIA, AMD or Intel, or from your laptop maker if its GPU needs OEM drivers. Don’t run it yet.
3. Know your password and BitLocker key, as described above.
4. Note your GPU settings. The DDU guide warns that settings and profiles in your GPU control panel are removed, so you may need to redo refresh rates, color settings and similar.

The developer also advises excluding the DDU folder from security software to avoid issues. Only do that for a copy whose hash you have verified, and only for the DDU folder.

How to use DDU: the developer’s procedure

1. Disconnect from the internet, or completely block Windows Update, until the new driver is installed. The developer marks this as a must, because Windows can otherwise download a driver on its own. DDU’s options also include a setting meant to stop Windows Update from fetching drivers.
2. Extract DDU to a folder on a local drive. The guide suggests a “DDU” folder on the desktop. Read the Readme file, then launch Display Driver Uninstaller.
3. Boot into Safe Mode. The developer: “for absolute stability when using DDU, Safemode is always the best.” DDU can reboot into Safe Mode for you. The guide warns to use DDU’s “Enable Safe Mode dialog” option only after you have tried entering Safe Mode the usual way at least once, or you may get stuck in Safe Mode.
4. Check Options. The guide recommends ticking removal of the C:\NVIDIA and C:\AMD folders, where installers unpack their files, unless you keep something else there.
5. Select the device type and vendor from the drop-downs on the right.
6. Choose a button:
   • Clean and restart for a normal cleanup before installing a driver.
   • Clean and do NOT restart when you need to remove a second vendor, for example AMD and then NVIDIA.
   • Clean and shutdown when you are about to swap the graphics card.
7. Wait. The guide says the screen may go black for a few seconds while the driver is removed. That is normal.
8. After the reboot, install the driver you downloaded, restart if asked, and reconnect to the internet.

If you run DDU in normal mode instead of Safe Mode, the developer’s instruction is: clean, reboot, clean again, reboot.

A lighter alternative for NVIDIA cards

For a driver that installed but misbehaves, NVIDIA’s support article describes a manual clean install. Download the latest driver, close background apps including GPU tuning and monitoring tools, run the installer as administrator, choose Custom (Advanced), tick Perform a clean installation, and reboot at the end. Try this before DDU. If you use the NVIDIA App, see NVIDIA App vs GeForce Experience for what the app installs.

AMD users with an installer that keeps looping should read our AMD Adrenalin install loop fix before reaching for DDU.

What DDU does not do

• It does not install drivers. You install the new driver yourself afterwards.
• It is not made by NVIDIA, AMD or Intel. The developer says they “should not be held responsible for anything that may go wrong with this application.”
• It does not keep your GPU control panel settings.
• It is not a performance booster. It cleans up; any gain comes from fixing a broken install.

Questions

Is DDU safe?

The official, signed build from Wagnardsoft does what it says: it removes graphics drivers. The risk is procedural. Follow the developer’s steps, have your password and BitLocker key, and create a restore point first.

Is DDU free?

Yes. Wagnardsoft lists it at no cost and accepts optional tips, Patreon support and merchandise purchases.

What is the latest DDU version?

18.1.6.0, released September 15, 2026, as of September 26, 2026.

Portable or installer version?

Both are official and both have published hashes. The portable build is a self-extracting archive you run from a local folder.

Do I need to uninstall the driver before running DDU?

No. The developer says you do not need to uninstall the driver first.

Why disconnect from the internet?

So Windows Update doesn’t install a driver of its own between the cleanup and your install. The developer says to stay offline, or block Windows Update, until the new driver is in.

Can I use DDU on a GPU I’ve already removed?

Yes. The DDU guide says to select that vendor before cleaning.

My PIN doesn’t work in Safe Mode. What now?

Use your account password. The developer suggests turning off “For improved security, only allow Windows Hello sign-in for Microsoft accounts on this device” under Settings > Accounts > Sign-in options. He also says you must use your password once in normal mode before it works in Safe Mode.

Is Guru3D an official DDU source?

Guru3D describes itself as an official download partner. The developer’s policy names wagnardsoft.com as the official location and allows credited trusted mirrors. Verify the hash either way.
