Run Windows Update Troubleshooting

As you can see from the section above, several areas can cause this error message. However, in the vast majority of possible scenarios, the problem is caused by an EC component (rather than an external process or service).

For this reason, you should start the troubleshooting process by checking to see if your Windows can solve the problem automatically (without any manual adjustments on your part). You can do this by running the Windows Update diagnostic tool.

If the problem you are experiencing is already documented by Microsoft, the Windows Update diagnostic tool should already have a recovery strategy that will automatically fix the problem. Several Windows users who also had problems resolving the 8024001B error reported that they were able to get to the root of the problem by running this utility and applying the recommended recovery strategy.

If you’re not sure how to use the Windows Update utility to diagnose the problem, follow the step-by-step instructions below:

  1. Open the Run dialog box by pressing the Windows + R key combination. Then type “control.exe / Microsoft.troubleshooting name” and press Enter to open the Troubleshooting tab of the Classic Control Panel interface.
    Note: If you see UAC (user account request), click “Yes” to grant administrative privileges.
  2. While in the Classic Control Panel interface, use the text box in the upper right corner to search for “Troubleshooting”. Then click on “Troubleshooting” in the list of results on the left.
  3. While in the “Troubleshooting” window, go to the menu on the right and click on “System and Security”. Then in the list of troubleshooting strategies, click on Windows Update (on Windows).
  4. When the Windows Update Troubleshooting Assistant window opens, first click on the Advanced link, and then make sure that the Automatically Troubleshoot Apply checkbox is checked. Then click Next to go to the next menu.
  5. Wait for your utility to detect problems. If a viable repair strategy has been found, it will be presented to you on the next screen. To take advantage of this, click Apply this repair and wait for the process to complete.
  6. If the computer does not restart automatically, run it yourself and see if the problem is resolved the next time you start the system by trying to update the computer.

If the process still fails with the same 8024001B error, go to the next method below.

Resetting all EC components

Another common scenario that can cause error 8024001B is a WU (Windows Update) mismatch, which effectively prevents the computer from finding and installing new updates.

We have seen this behavior with several affected users, and in the vast majority of cases, they were able to fix it by resetting all the items and dependencies involved.

If you think this scenario might work for you, follow the guide below to learn, step by step, how to manually reset all Windows Update components (using the advanced CMD prompt). Here’s a quick guide on how to do it:

  1. Press the Windows + R keys to open the “Run” dialog box. Then type “cmd” in the text box and press Ctrl + Shift + Enter to open the extended command prompt. When prompted for UAC (User Account Control), click Yes to grant administrator access.
  2. Once on the extended CMD prompt, enter the following command in order, pressing Enter after each command to stop all major EC services:
    net stop wuauserv
    network stop cryptSvc
    network stop bits
    network stop my server
    Note: After running these commands you will stop all of the important Windows Update services (Windows Update, MSI install service, crypto service, and BITS service).
  3. After successfully shutting down all these services, run the following commands at the same CMD command prompt and press Enter after each command to rename the SoftwareDistribution and Catroot2 folders
    ren C: WindowsSoftwareDistribution SoftwareDistribution.old
    ren C: WindowsSystem32catroot2 catroot2.old
    Note: These two folders are important since they are responsible for storing the update files used by the Windows Update component. Renaming them essentially forces the operating system to create new instances to take their place and bypass any type of file corruption.
  4. After you’ve gone through step 3, enter the last commands in order, hitting Enter after each to restart the same services you previously disabled:
    wuauserv network start
    network start encryption
    network start bits
    network start messer.
  5. Try again to check for updates to see if the 8024001B error code is still displayed.

If the same problem still exists, move on to the next possible solution below.

Using the system restore utility

If this behavior occurred recently, a recent system change may have caused this problem with the WU component. It is possible that this problem was caused by a third-party service or process.

Since it is not possible to list all the potential culprits, we will present a cost-effective approach – the use of a system recovery utility.

This tool is able to use a previously created snapshot to restore your entire computer to a previous state when the factors contributing to error 8024001B were not present.

Remember that by default Windows is configured to periodically record a system restore snapshot when you perform important actions (e.g. installing a critical update, installing a driver, etc.). If you have not changed this behavior by default, you should have enough restore points from which to choose.

Note: Before you use this utility, keep in mind that any changes you have made since the restore point was created will be lost if you use it to restore your device to an earlier state. This includes installed apps, drivers, third-party apps, games, etc.

If you are aware of the implications and still want to proceed, follow the instructions below to begin the recovery process:

  1. Press Windows + R to open the “Run” dialog box. Then type “rstrui” in the text box and press Enter to open the system restore menu.
  2. Once you have reached the main System Restore screen, click Next to move to the next screen.
  3. On the next screen, first, make sure that the “Show more recovery points” checkbox is selected. Next, compare the dates of each restore point and select the one that is older than the problem you encountered. Once you have selected the correct system restore, click Next to move on to the next menu.
  4. Once you reach this point, the utility is ready to use. All you have to do is start the recovery process by clicking Finish.
  5. After a few seconds, the computer will reboot and the previous state will be mounted. Once the process is complete, try again to check for updates and see if you still have the same problem.

If you still see error code 8024001B, go to the last method below.

Update all operating system components

If you were unable to bypass error 8024001B using one of the above instructions, you can assume that you are dealing with a system file problem that cannot be resolved in the usual way. If this scenario applies, the only viable solution that should fix the problem is a procedure that updates all Windows components.

A complete reset of the system files can only be done using two procedures: a clean installation or a repair installation (in-situ repair). A clean installation is easier to perform, but its main drawback is that it does not allow you to keep your files (applications, games, personal media, user settings, etc.).

If you are looking for the most efficient method, you should choose a repair shop (on-site upgrade). It is a longer procedure, but it only affects the system components and allows you to keep all your personal data (including applications and games).
