What causes the “Windows Update components must be repaired” error?

At the time of writing, there isn’t a definitive cause for this problem. However, the user base of Windows 10 is known for providing useful feedback, allowing us to pinpoint a few possible sources.

  • The Windows Update Components are damaged or corrupted. The most likely cause of this error is the fact that the Update Components themselves were corrupted or damaged by an external source. The best thing you can do in this case is to reset these components and start with a clean plate.
  • There’s a problem with verifying your operating system. Windows Update needs to be able to verify the legitimacy of your system. If this process is unable to go through, you may end up seeing the “Windows Update components must be repaired” error when running the Update troubleshooter.
  • You don’t have enough available space on your device. Some users report that they see this error when trying to install a Windows 10 update to a disk that doesn’t have enough free space.
  • The date and time zone settings on your PC are incorrect. Rarely, but in specific cases, a wrong date or time zone setting can break Windows Update.
  • A third-party antivirus application is messing up your update. Antivirus solutions are notorious for causing Windows 10 system issues on your computer. It’s possible that the app you have installed right now is blocking Windows Update from performing its job.

While some of these are only general causes, some users report that they may lead to the “Windows Update components must be repaired” error showing up while you run the Update troubleshooter.

Fix: “Windows Update components must be repaired”

Now that we’ve taken a look at some possible sources for this issue, it’s time to resolve it. You can find multiple methods for getting rid of this error below. Some of them are general troubleshooting tips, while other methods focus solely on Windows Update.

Solution 1: Boot your system in Safe mode

Safe mode allows your computer to boot with nothing but the necessary Windows 10 components. By doing this, you may be able to identify that a third-party app caused the “Windows Update components must be repaired” error, and it’ll allow you to update your system.

  1. Hold the Windows + R keys on your keyboard to launch Run. Type in “msconfig” and click the OK button.

  6. Restart your computer and check if you can update Windows.

Solution 2: Reset the Windows Update Components

After you verify that Safe mode doesn’t work, we recommend you follow up by resetting the Windows Update Components altogether. This is a long process that requires the use of the Command Prompt. However, if you correctly follow our steps, this solution is most likely to restore your updates.

  1. Press the Windows + R keys on your keyboard to launch the Run utility. Type in “cmd” and  press Ctrl + Shift + Enter. This is going to open the Command Prompt with administrative permissions.

    1.  Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak
    2.  Ren %systemroot%\system32\catroot2 catroot2.bak
  5. After all of these steps, you can reset the BITS service and the Windows Update service security descriptor. To do this, input the following commands into the Command Prompt, pressing Enter after each one:
    1. sc.exe sdset bits D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)

Solution 3: Perform a System File Checker scan

The System File Checker, also known as SFC scan, allows you to automatically fix a number of issues on your system. By running it, you may be able to get rid of the “Windows Update components must be repaired” error.

  1. Press the Windows + R keys on your keyboard to launch the Run utility. Type in “cmd” and  press Ctrl + Shift + Enter. This is going to open the Command Prompt with administrative permissions.

In specific cases, having the wrong date and time zone settings may cause problems with Windows Update. We recommend you double-check and correct any issues manually.

Solution 7: Temporarily disable your third-party antivirus

As mentioned above, third-party antivirus applications can block Windows Update from being able to perform updates. If this is the case, you need to disable them temporarily and update your system while they’re turned off.

If you don’t know how to disable your antivirus, we recommend looking up its name and turning to a support website or contacting the customer support.
