The Media Creation Tool is a very useful asset for any Windows user. It lets you create a bootable CD or USB drive with the setup for your operating system, and then use it for reinstalling or fixing the OS in case something goes wrong. However, there are situations when it simply won’t work, such as when you get the 0x80070456 error. This error means that there are corrupt files within your system drive, and you won’t be able to use the Media Creation Tool unless you reset it completely.
Fortunately, this can be fixed pretty easily, as long as you follow the steps below. Before you follow them, do try the setup using a storage drive with a capacity higher than 8 gigabytes. The tool might ask you for more than 4GB, but the installation files are larger than that and it will fail if you don’t have a drive larger than 8GB. If you’re still facing the problems, move on to the method below.
Reset the Media Creation Tool
Note that you need to be the administrator of your computer, otherwise you won’t be able to do the steps due to ownership reasons.
- Press the Windows key, and type in Control Panel, then open the result. If you have Windows 10, you can also press simultaneously the Windows and X keys, and choose Control Panel from the menu.
- In the top right corner, choose Large Icons or Small Icons. Open File Explorer Options.
- Navigate to the View Scroll down until you find Hidden files and folders, and choose to Show hidden files, folders and drives.
- Close the File Explorer Options, as well as the control panel, and open My Computer or This PC, depending on which version of the OS you have. Open your OS partition (usually the C: drive).
- Select the $windows.~WS and $windows.~BT folders, and delete both of them. Close the File Explorer.
- Press the Windows key again, and type in Disc Cleanup. Run the tool, and let it finish.
- Once everything is done, reinstall the Media Creation Tool. It should be working flawlessly now.
