What is the cause of Windows update error 0xc1900201?

What is the cause of Windows update error 0xc1900201?

It is by far the easiest fix for Windows Update Error 0xc1900201. It is sometimes possible to fix the update error by restarting the computer after experiencing a glitch. If you encounter a glitch with your app or document, close all of them so you don’t lose any progress. When you restart your computer, try running the update again.

In order to investigate this issue, we reviewed a number of user reviews and tried a variety of repair strategies that were suggested by concerned users who had successfully fixed the issue. According to the research, this error code can be triggered by a variety of scenarios. Here is a short list of possible culprits:

Windows Update Blocked Between Updates: Under certain circumstances, this particular error code can occur because a faulty Windows update is blocked pending. In some cases, this problem may cause the entire WU component to stop and prevent the user from keeping the operating system version up to date. In this case, you can solve the problem by running the Windows Update diagnostic program to automatically detect and resolve the problem.

Faulty WU component: If the user cannot install new updates (not just one), it is likely that one or more WU components have failed and interrupted the update process. If this scenario applies, you may be able to resolve the problem by resetting all WU components (either with an automatic agent or manually with an extended CMD prompt).

Scammers send messages saying they want you to pay “customs fees” or some other sort of fee in order to win the lottery. However, you have not won the lottery, and your personal details are being divulged.

The operating system already cloned: This problem very often occurs in situations where the user has previously migrated their operating system from a hard drive to a new SDD format. The mismatch is the result of a failed verification attempt due to a hardware change. In this case, you can solve the problem by using the registry editor to change the PortableOperatingSystem value.

Damaged system files: In rare cases, this problem is related to corrupted system files, which eventually affects component updates. In this case, the problem can be solved either by running some built-in utilities that can repair corrupted components (DISM and SFC) or by updating each Windows component (via a recovery installation or a clean installation).

Below is a list of possible solutions that other users have successfully used to get to the bottom of error 0xc1900201. If any of the above scenarios apply to you, see the next section on how to solve the problem.
