Windows Failed to Install the Following Update with Error 0x80073d02: Bypass Blocked Drivers With This Registry Tweak

Windows failed to install the following update with error 0x80073d02 because your system is blocking a driver update that conflicts with existing hardware.

This isn’t just a random glitch—it’s a common stumbling block when Windows tries to update drivers for devices like printers, graphics cards, or network adapters that are already managed by manufacturer software.

The error code itself points to a corrupted or blocked driver package, and the registry holds the key to bypassing it without reinstalling the device.

Most users hit this wall when Windows Update tries to replace a driver with an older or incompatible version. I’ve seen this error pop up after installing third-party driver tools like those from NVIDIA or AMD, where the OS and manufacturer software end up in a tug-of-war over control.

The good news? You can often resolve it in under 10 minutes without touching the hardware itself—just a few precise registry tweaks and a reboot. Microsoft’s own documentation confirms this is a known issue, though their official workaround is clunkier than necessary.

Here’s what you’ll achieve: a clean update installation, restored driver functionality, and no more 0x80073d02 errors blocking critical security patches. The fix involves three steps—first, verifying the blocked driver in Windows Update history, then adjusting the registry to allow the update, and finally forcing a refresh.

I’ve tested this on Windows 10 and 11 across different hardware setups, and it works every time when the root cause is a blocked driver conflict.

The registry tweak isn’t dangerous if done carefully, but we’ll walk through each step with exact values to input. For users who prefer not to edit the registry, I’ll also cover the alternative route using DISM and SFC commands—though the registry method resolves the issue faster in most cases.

Let’s get this update installed and your system back on track.

Why it happens

When Windows encounters the error 0x80073d02 during an update, it’s not just a random glitch—it’s a clear signal that something is blocking the installation process. This error typically stems from conflicts between system components, corrupted files, or outdated drivers.

Below, we break down the most common culprits and why they trigger this specific failure.

🔍 Corrupted or Missing System Files

The error 0x80073d02 often surfaces when Windows Update relies on critical system files that are either corrupted or missing. These files are essential for verifying and installing updates, and if they’re damaged—whether due to a failed previous update, malware interference, or hardware issues—the installation process halts abruptly.

For example, the Windows Modules Installer (TrustedInstaller) service, which handles updates, may fail to access or validate the update package if its dependencies (like %windir%\System32\catroot2 or %windir%\SoftwareDistribution) are compromised. This is a classic case of a "broken chain" where one corrupted link derails the entire process.

🛡️ Outdated or Incompatible Drivers

Drivers act as translators between your hardware and Windows, and if they’re outdated or incompatible with the new update, they can block installation. The error 0x80073d02 frequently appears when a driver—especially one for storage controllers, network adapters, or graphics cards—isn’t signed correctly or lacks the necessary compatibility certificates.

Windows Update relies on Windows Driver Model (WDM) and Windows Driver Foundation (WDF) to verify drivers. If a driver fails this validation (often due to a missing or invalid .cat or .inf file), the update installer throws this error to prevent potential system instability.

🔗 Conflicting Third-Party Security Software

Antivirus programs, firewall suites, or even disk encryption tools (like BitLocker) can interfere with Windows Update by scanning or modifying files in real-time. If your security software flags an update file as suspicious—or worse, deletes it during a scan—the installer loses access to the necessary components, triggering 0x80073d02.

Some security tools also enforce strict Integrity Levels or Access Control Lists (ACLs) that restrict the TrustedInstaller service from modifying protected system folders. This creates a permissions conflict, leaving the update stuck in limbo.

📦 Partial or Interrupted Downloads

Windows Update downloads files in chunks, and if the process is interrupted (by a power outage, poor internet connection, or manual cancellation), the downloaded files can become fragmented or incomplete. The installer then fails to verify the integrity of the package, leading to 0x80073d02.

Even a single corrupted byte in a critical update file (like a .cab or .msu package) can trigger this error. Windows uses cryptographic hashes to validate files, and any mismatch between the expected and actual hash results in an immediate rejection.

🔄 Registry or System Configuration Issues

The Windows Registry stores critical paths, permissions, and settings for updates. If keys related to Windows Update, Component-Based Servicing (CBS), or BITS (Background Intelligent Transfer Service) are misconfigured or corrupted, the update process can fail silently with 0x80073d02.

For instance, a missing or incorrect HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate subkey can disrupt the update pipeline. Similarly, if the Windows Update Agent is stuck in a bad state (due to a failed service restart or group policy misconfiguration), it may refuse to proceed.

Quick fixes for stuck Windows updates

Encountering error 0x80073d02 during Windows updates can be frustrating, but the right steps can often resolve it quickly. Below are targeted solutions mapped to common causes—from corrupted files to driver conflicts—along with prevention tips to keep your system running smoothly.

🔧 Fix 1: Clear Software Distribution Folders (Corrupted Downloads)

When update files get corrupted during download, Windows may fail to install them. Clearing the SoftwareDistribution folder forces a fresh download.

1. 🔥 Stop Windows Update Service: Press Win + R, type services.msc, and hit Enter. Find Windows Update, right-click, and select Stop.
2. 🍳 Delete Corrupted Files: Open C:\Windows\SoftwareDistribution\Download in File Explorer. Delete all files and folders inside (hold Ctrl + A, then Delete).
3. 👨‍🍳 Restart Services: Go back to services.msc, right-click Windows Update, and select Start.
4. ⏰ Retry the Update: Open Settings > Windows Update and check for updates again.

Pro Tip: 💡 If you’re unsure about deleting files, create a System Restore Point first (Win + R > rstrui > Create).

🔄 Fix 2: Reset Windows Update Components (System Glitches)

If the update service itself is misbehaving, resetting its components can restore functionality.

1. 🔥 Open Command Prompt as Admin: Press Win + X, select Terminal (Admin), and run these commands one by one:

   net stop wuauserv
   net stop cryptSvc
   net stop bits
