KB4571744: Typically, Microsoft releases new mandatory cumulative updates on the second Tuesday of each month and then offers the optional updates later in the month.
So while the Patch Tuesday less than five days away, you may have thought the company missed the optional updates for the 2004 version of Windows 10 this month. Error.
Today, the company released KB4571744 for the Windows 10 May 2020 Update, increasing the version number to 19041.488.
As is usually the case with these updates, there are many fixes, such as adding fonts, fixing unloaded ActiveX content, working with File Explorer, and more.
