# NVIDIA driver clean install: when DDU helps, and when it is overkill

> Install or clean-install an NVIDIA driver on Windows 11 without driver packs: normal update, custom clean install, DDU last resort, and verification.

**Tested on**

- Build: 26300.9457
- Edition: Pro (26H2)
- Architecture: x64
- Evidence: E1
- Verified: 2026-10-28

## The short answer

For a normal driver update, use **NVIDIA App** or the official installer and choose the **custom/clean install** option when you need it. Use **DDU** only when a normal uninstall fails, you swapped GPU vendors, or you have a reproducible driver corruption.

DDU is not a monthly maintenance ritual. Running it every update adds risk without improving performance.

## Normal update vs clean install

| Situation | Path |
|---|---|
| Monthly driver update | NVIDIA App / official installer, express install |
| GPU upgrade within NVIDIA | Custom install, “Perform a clean installation” |
| Switching NVIDIA ↔ AMD/Intel | DDU in Safe Mode, then install the new vendor driver |
| Persistent display/black-screen issue | DDU + clean install, after a restore point |
| Laptop with OEM-modified driver | Check the OEM page first; generic driver may break hotkeys |

## Before you start

1. Create a restore point.
2. Download the correct driver for the **desktop or laptop** GPU and Windows build.
3. Note the current driver version: `nvidia-smi`.
4. Close games, capture tools and overclocking utilities.
5. Have the installer offline if the network is unreliable.

## Option A — NVIDIA App

1. Install/update NVIDIA App from NVIDIA’s site.
2. Open **Drivers** and check the recommended branch.
3. Choose **Custom installation** if you want a clean install or to exclude components.
4. Let it uninstall/install and reboot if asked.
5. Verify with `nvidia-smi` and Device Manager.

## Option B — official installer

Download the driver package, run it as administrator, choose **Custom**, and select **Perform a clean installation** when needed. This removes the old driver settings and profiles; you will lose per-game NVIDIA profiles, so export/note them first.

## Option C — DDU last resort

Use Display Driver Uninstaller only when:

- the installer fails repeatedly;
- the display is broken after a normal rollback;
- you are changing GPU vendors;
- a clean install still leaves the same corruption.

Procedure: download DDU and the new driver first, boot Safe Mode, run DDU for the GPU vendor, reboot, install the new driver, reboot, verify. Do not run DDU with the only copy of the installer still on the network.

> **Caution: Laptop drivers are not generic**
>
> A laptop GPU may use an OEM-customised driver for power switching, fan curves and display output. The NVIDIA generic package may install but break hybrid graphics or hotkeys. Check the OEM support page before forcing it.

## Troubleshooting matrix

| Symptom | Likely cause | Next step |
|---|---|---|
| Installer says “already installed” | Partial install/registration | Custom install or DDU after a restore point |
| Black screen after install | Display mode/driver mismatch | Boot safe mode, roll back, reinstall |
| `nvidia-smi` missing | Driver not loaded or wrong package | Check Device Manager, reinstall the full package |
| Laptop hotkeys broken | Generic driver replaced OEM stack | Reinstall the OEM package |
| Game stutters only after update | Shader cache/driver branch | Clear shader cache, test the previous branch |
| Code 43 | Driver/VM/hardware issue | Check event log; do not “fix” with a random registry patch |

## Verify
## Verify

```powershell
nvidia-smi
Get-PnpDevice -Class Display | Select-Object FriendlyName, Status
```

Check:

- the driver version matches what you installed;
- Device Manager has no warning;
- the display runs at the expected resolution/refresh;
- one game or GPU workload launches without a black screen;
- laptop hybrid graphics still switches correctly.

## What not to do

- Do not use a “driver pack” or “booster” utility.
- Do not disable Windows Update to stop driver updates; use the vendor policy/WU settings instead.
- Do not DDU every month.
- Do not install a Game Ready driver over a broken installation and call it clean.
- Do not overclock while validating a new driver.
