One of the most revolutionary features of Windows 10 when it launched was its new Windows Settings app, which was designed to make configuring the operating system easier than ever, but it may have inadvertently added a major security hole, according to a security researcher.

According to Matt Nelson, a security researcher for SpecterOps, the file type in question is '.SettingContent-ms'. This was introduced in Windows 10 in 2015, and its aim was to create shortcuts to Windows 10 settings pages. The idea was that this was a more user-friendly way of configuring Windows 10, compared to the old Control Panel of previous versions.
