Security expert has found a vulnerability in Windows 10 which allows to crash NTFS file systems with a single line of code. This causes hard drive crashes, which in only a few cases could be fixed by rebooting the computer.
Even worse, the code is embedded in HTML and will be triggered when opening a folder with a file containing this code in its name. Simply put, the hard drive can crash simply because the user clicks on a link or opens a shared folder where someone has put such a file.
The problem is reproduced even if you just paste the code into the browser (except for Internet Explorer). Almost immediately a hard disk error notification appears.
Microsoft has responded to this message almost a week after it was published and promised to fix it in a future security patch. Until then users are advised to be careful when clicking on links and downloading files from unknown senders.
