Windows 10: Error Code 0x80042405-0xa001a on MCT

Why do I randomly get Error Code 0x80042405-0xa001a when trying to create a Windows 10 USB in MCT. I contacted Microsoft via live chat and all they can recommend is to purchase Assure Software Support which costs $150 per year to get further help. The USB flash drive is currently an MBR FAT32 format.

It tries to - it's when it fails that you get that error code. Did it leave your usb in an unformatted state? It would if it had encountered a gpt usb. You can test it, it's easily reproducible. Convert a usb to GPT with MiniTool Partition Wizard, then try to use it with the MCT.

The only other reported case I can find of error 0x80042405 - 0xA001A that has been solved was attributed to a third-party AV (F-Secure) getting in the way of the MCT.

This seems to be a common error for some, MCT can be fickle when creating and writing to thumb drives. Sure you have, but ensure you are getting the correct version. Language, home/pro, and the bits.. 32-bit or 64-bit. If that fails again, choose the option to just create the ISO only, you can choose where to let Windows create it. Then use another common Thumb Creator to actually make the thumb drive, Rufus. It will handle all the formatting and creation for you.
