Because the problem usually appears due to corrupted segments, we will try running an in-built utility to detect and restore them. Here is how:

  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.

Now, you can give it a try installing the update again. If the error still persists after running these steps, go to the next method below.

2. Clear up Windows components

When there is an error popping on your PC, there is a chance it is due to overloaded libraries. Over the usage, they may become junked with unnecessary components that lead to the instability of different services. Below, we show how to clear them out via Task Manager and DISM.

By using Task Manager

  1. Press Windows + R combination to open run prompt, then paste taskschd.msc and click OK.
  2. On the left pane, navigate to Library>Microsoft>Windows>Servicing.
  3. Once done, right-click on StartComponentCleanup and choose Run.
  4. Wait till the process is finished, restart your computer, and try to install the conflicting update once again.

By using DISM

This method does exactly the same as above, so you can choose any of them.

  2. Now paste this command dism /online /cleanup-image /startcomponentcleanup and hit Enter.
  3. Once completed, restart your PC and check if the error persists.

3. Turn off/delete third-party software

Third-party software like antivirus has a tendency to cause malfunctions in some services. It can both suspect and mistake suspicious processes happening in your system. For some reason, even Windows services may be blacklisted and restricted by anti-malware software. Because we do not know whether it is a case or not, try to disable a non-native antivirus if you have it installed. Besides antivirus being a culprit for such errors, unwanted or malicious programs can cause the same effect as well. If you remember installing a new piece recently, try to delete it and see the difference. Maybe it will resolve the issue.

  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 KB update (on top of the list).
  5. Once done, search and download the noted update in the Microsoft Update Catalog.
