The programme for creating a clone of Windows 10 is really useful in a variety of ways. In the event of a machine malfunction, it allows customers to easily recover their Windows operating system. They can also keep a hard copy of their operating system for enhanced security, among other things.

Regrettably, it does not always work as it should. Many people refer to the 0x80042405 – 0xa001a error as 0x80042405 – 0xa001a when anything goes wrong.

What is the nature of the problem, and what does the error code mean? What plan do you have to get rid of it?

Not to worry; we’ll go over all of this and more in this tutorial.

The Issue Is Clearly Defined


Despite the fact that customers have reported a range of troubles with Windows 10’s Media Creation Tool, we do know a few things for certain:

  • This problem affected even customers who had brand-new USB Flash Drives.
  • Formatting the USB Flash Drive before executing the utility did not solve the problem.

That being said, you should avoid acquiring a new USB flash drive to remedy this issue because your present one is most likely fine.

When attempting to use this software, you should not be alarmed if you see an error message such as 0x80042405 – 0xa001a Media Creation Tool.

Although the MCT (Media Creation Tool) appears to be one of the most useful tools, it is not without flaws.

Now, let’s talk about the real issue. In this case, there are several things that can be done. One of them is more like a work around. Look at this.

Workaround For Critical Situations – Rufus

You already know that this isn’t the best technique to handle the problem, yet it works every time.

This is the ideal solution if you’re in a rush and need to generate a bootable disc to repair your computer. It’s adequate if you don’t want to use any other media creating tool than the one that comes with Windows. You can skip this workaround and go straight to the next section.

It can be used to make bootable USB installation media from ISO files or to work on a machine that does not have an operating system. Rufus is a free application that can help you complete these chores. It is not required to install it.

Windows 0x80042405–00001a If you can’t fix the problem with the Media Creation Tool, this method should save you a lot of time and trouble.

You can repeat this if you don’t want to use anything other than MCT.

Step 1: Before Using The Media Creation Tool, Copy It To Your USB

Many users claim success with this strategy for resolving the 0x80042405 – 0xa001a Media Creation Tool Error.

Download and install the Windows 10 Media Creation Tool on the USB drive you want to use as a bootable disc.

If it is already on your computer, simply transfer it to the USB device in question.

It’s now time to run MCT from the USB device and use it normally (as though it was placed somewhere else on your PC).

If this helps, you won’t see the error again.

Step 2: As An Administrator, Run “MCT”

Running apps with administrator privileges helps you avoid complications such as permissions and restrictions.

By running the Media Creation Tool as an administrator, you may be able to remedy the problem.

We believe you should because it only takes two clicks. It doesn’t matter if it doesn’t work. You won’t have spent an excessive lot of time on it.

Locate the “Media Creation Tool” using your computer’s mouse. From the context menu, select “Run as Administrator.” If you utilised the USB drive technique in the previous step, the tool should be on it.

After starting the utility, you should be able to use it without getting the issue again.

Your Third-Party Antivirus Software Should Be Disabled


There is no built-in antivirus programme in Windows that will detect the Media Creation Tool as a threat. Given that they are both manufactured by Microsoft, this is unsurprising. A file obtained from the official Microsoft website is always safe to use.

However, some third-party antivirus programmes may identify it as a potential danger and quarantine it, preventing you from using the tool at all.

To reduce the chance of infection, we recommend that you disable all software except the built-in Windows 10 antivirus (Windows Security) before using the Media Creation Tool.

This could help you avoid and perhaps resolve the 0x80042405 – 0xa001a error.

Step 3: Make Sure There Is Enough Space On Your USB –  Choose A Different File Type

Several consumers reported that this problem was caused by a lack of space on their USB sticks. Delete some files from the flash drive or format it to guarantee you’re not having the same problem.

Check to see if your USB flash drive is already FAT32 formatted. Then attempt to use the tool again. Some customers reported being able to use their USB in NTFS format, while others claimed being able to use it in FAT32 format.

Experiment with both and find which one works best for you.

Step 4: Change The USB Port On Your Computer

While experiencing a problem with your USB Port is uncommon, we believe it is worth investigating because it only takes a few seconds.

What you should do is as follows:

  1. It is crucial that nothing on your USB drive is currently running on your computer.
  2. You can safely remove the USB device by going to the bottom-right corner of your taskbar and clicking on the arrow that points up. On the next screen, click on Safely Remove Hardware and Eject Files.

3. Make sure the device is out of the way. Then, insert it into a different USB port and try using the Media Creation Tool again.

Some folks found this helpful, but not everyone. It can only be a good idea if your USB port is broken. Take a chance, though. You may find it useful.
