There's a vulnerability in Windows 10 that can corrupt the file system of an NTFS storage disk. The vulnerability can be triggered by standard and low privileged user accounts, by entering a single-line command in the command prompt.

Bleeping Computer discusses various ways how this zero-day exploit can be triggered.
In August 2020, October 2020, and finally this week, infosec researcher Jonas L drew attention to an NTFS vulnerability impacting Windows 10 that has not been fixed.

When exploited, this vulnerability can be triggered by a single-line command to instantly corrupt an NTFS-formatted hard drive, with Windows prompting the user to restart their computer to repair the corrupted disk records.
All versions of Windows 10 since around Windows 10 build 1803 are vulnerable. Bleeping Computer reached out to Microsoft and got to hear the bug will be fixed "as soon as possible."
