There are special repair utilities for Windows, that can solve problems related to registry corruption, file system malfunction, Windows drivers instability. We recommend you to use Advanced System Repair to fix the “Windows Update error 0x8009001d” in Windows 10.

1. Use Windows Update Troubleshooter

The first measure to help you stamp on the 0x8009001d error is using Windows Troubleshooter. This is an in-built utility capable of resolving temporary issues appearing on a PC. Although it is usually not enough to solve the problem completely, you should still give it a try using the steps below.

  1. Open Settings via the Start menu or press Windows key + I buttons together. Navigate to Update & Security > Troubleshoot.
  2. On the right pane, locate Windows Update and click Run the troubleshooter.
  3. Finish the process following the on-screen instructions and restart your PC.

2. Update all third-party software installed

If you have pending updates of already installed apps in the Microsoft Store, this is the right time to download them. Some applications may have crucial updates awaiting the installation that solve compatibility issues with other software. Even third-party programs may have some frictions with official Windows services leading to the corresponding errors. Thus, try to update all the installed software through the Microsoft Store. Here is how:

  1. Open Microsoft Store from the taskbar or through the search panel.
  2. On the top right of the window, click on the arrow-like button looking downwards. If you do not see this button, click on the three-dots button and choose Downloads and updates.
  3. Now you will see a list of applications installed.
  4. Click Get Updates and wait until Windows installs all pending updates.

Finally, you can restart your PC and try to install the update again. If nothing works out, go to other steps underneath.

3. Turn off/delete third-party software

Not everybody knows, but third-party software like antivirus may be able to cause some malfunctions in Windows services as well. The error may appear when anti-malware software mistakes and blocks a suspicious process running over your system. For some reason, even Windows services tend to become part of this list getting restricted by anti-malware software. As we cannot identify it without a manual check, try to disable a third-party antivirus if you have it installed. Also, it is worth mentioning that unwanted or malicious programs can lead to same consequences as well. If you remember installing something new recently, try to remove it and download the update again. If you are unsure how to get rid of malicious programs properly, we recommend you to download a great and trusted antivirus developed by Malwarebytes (use the button below).

4. Install the necessary update in Safe Mode

As we mentioned, third-party software may be able to raise incompatibility with Windows Updates. For this exact reason, you can boot up your PC in Safe Mode. This option will launch your system only with the default configuration settings, which will prevent third-party programs from interacting with Windows processes. Here is how:

  1. Open Settings as we did above.
  2. Navigate Update & Security > Recovery > Advanced Startup.
  3. Then, click Restart Now.
  4. Your system will restart and boot with the Windows Recovery Environment.
  5. Whilst there, choose Troubleshoot > Advanced options > Startup Settings.
  6. Now click on Restart and choose Enable Safe mode with Networking once it reboots.
  7. Finally, being in Safe Mode, try to install the conflicting update as usual.

5. Check integrity of the system files

Most troubleshooting experts tend to agree on the fact that corrupted files are usually the prime reason suspected in causing the issue. This is why it is important to check their integrity before getting to more advanced solution methods. Below, we are going to use both SFC (System File Checker) and DISM (Deployment Image Servicing and Management), which will detect and restore absent and damaged components. Here is how:

Using SFC

  1. Open Command Prompt by typing cmd into the searching box next to the Start Menu button.
  2. Right-click on Command Prompt and choose Run as administrator.
  3. Once the console is opened, type the sfc /scannow command and click Enter.
  4. When the fixing process is done, restart your computer.

Using DISM

  1. Open Command Prompt as we did in the previous step.
  2. Copy and paste this command DISM.exe /Online /Cleanup-image /Restorehealth.
  3. Click Enter and wait until Windows ends the scanning and fixing.
  4. Once done, restart your PC and install the update again.

6. Restart Windows components and Update service

This method helps you reset Windows Update settings. It is very helpful and recommended by experts if you want to resolve the issue. The whole procedure involves restarting BITS, Cryptographic, MSI Installer, and Windows Update services as well as renaming some update folders (SoftwareDistribution and Catroot2). These folders contain special signatures for Windows Updates. Based on this, we will compel Windows to delete corrupted elements and create update components from scratch. The way we are going to do it is via Command Prompt. Although this is a multi-step solution, it should not take too much time and knowledge to do it. Just follow the steps below:

  1. Open Command Prompt by typing cmd into the searching box next to the Start Menu button.
  2. Right-click on Command Prompt and choose Run as administrator.
  3. Copy-paste this list of commands one by one clicking Enter after each. (This action will disable services responsible for Windows Updates)
  4. net stop wuauserv
    net stop cryptSvc
    net stop bits
    net stop msiserver

  5. Then, we have to rename the above-mentioned folders. Simply paste these commands by clicking Enter after each.
  6. ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    ren C:\Windows\System32\catroot2 Catroot2.old

  7. Finally, all left to do is to turn the disabled services back. So apply these commands likewise we did previously.
  8. net start wuauserv
    net start cryptSvc
    net start bits
    net start msiserver

  9. Now we are all done with it. Go to the Windows Update center and try to perform the installation again.

7. Clean up unnecessary system files

There is a number of users who capitalized on deleting redundant system files. This method involves wiping out recovery copies and cached files stored by your PC. It may be quite risky, as there will be no way to roll back to the previous version backed up on your system. Despite this, using such a measure helped some users immensely.

  1. Open This PC.
  2. Right-click on your main disk and choose Properties.
  3. Find and click on Disk Cleanup.
  4. Then select Clean up system files, check all the boxes, and click OK.
  5. Once done, restart your PC and try to install the update again.

8. Try to download a conflicting update from Microsoft Catalog

Cases when Windows struggles to receive cumulative updates from the server happen quite often. With this being a possible reason, let’s try to find and install the necessary update right from the Microsoft Catalog. Before doing so, we will have to note which update you need to install. For this:

  1. Press Windows key + I at the same time.
  2. Then navigate to Update & Security.
  3. On the right side of the window, choose View update history.
  4. After this, find and note the most recent update that filed to install (on top of the list).
  5. Once done, search and download the noted update in the Microsoft Update Catalog.

9. Use Media Creation Tool

We are going to end the list of solutions with an option to install updates via the Media Creation Tool. This is an official Microsoft utility allowing users to upgrade their systems to the latest version available. This procedure will not have any influence on your personal data but simply update your PC. In order to do it, follow the steps listed below:

  1. First, you have to download the utility from the Microsoft website.
  2. Then, execute the downloaded file.
  3. After agreeing with the Terms of use, there will be two options to choose from. Select Upgrade this PC now.
  4. Choose to Keep Personal Files to ensure they will be untouched.
  5. Finally, launch the process and wait until it ends.
  6. Hopefully, this method helped you combat the 0x8009001d error.
