This was done to appeal to the developer community who primarily uses Linux due to its ease of use when it comes to programming-related tasks. WSL works by taking Bash commands users type in a CLI, converting the shell commands to their Windows counterparts, processing the data inside the Windows kernel, and sending back a response, to both the Bash CLI and a local Linux file system.

A "critical" patch had been issued by Microsoft on 14 March 2017 to remove the underlying vulnerability for supported systems, nearly two months before the attack, but many organizations had not yet applied it. Those still running exposed older, unsupported op...
