Microsoft released the third cumulative update to Windows 10 last week. But surprisingly, the supporting document associated with the patch - known as KB3081438 - was devoid of any information pertaining to what the update contained, except that "it includes improvements to enhance the functionality of Windows 10". This surprised many users of the OS, keeping in mind that Microsoft was forthcoming about the fixes in the previous two cumulative patches. The company has now offered an explanation regarding its policy of change logs regarding Windows 10 patches. It seems like nobody is taking the time anymore to write proper changelogs. Application and even operating system updates are void of any accompanying info, so you have no idea what's new, changed, fixed, or improved. A unwelcome development.
