KB4571744: Usually, the Microsoft new mandatory cumulatives are released updates on the second Tuesday of each month and then offers optional updates later in the month.
So while the Patch Tuesday is less than five days away, you might have thought that the company skip the optional updates for the version 2004 of Windows 10 this month. Error.
Today, the company released KB4571744 for 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.
