Cumulative updates KB4284822, KB4284830 and KB4284833 for Windows 10

Microsoft released a whole bunch of cumulative updates for the company's Windows 10 operating system yesterday. The updates KB4284822, KB4284830 and KB4284833 include non-security fixes and improvements for Windows 10 version 1709, 1703, and 1607.

The company has not released an update for Windows 10 version 1803, the current version of Windows 10, yet but it is likely that one will be released that includes some of the fixes.

Windows 10 version 1607 is no longer supported on devices running Home or Pro editions of the operating system whereas versions 1703 and 1709 are still supported.

The updates are available as direct downloads from Microsoft's Update Catalog, Windows Update, and Enterprise update tools.
