It's "Patch Tuesday" time once again for supported versions of Windows 10. The monthly batch of cumulative updates are now rolling out to Windows 10 PCs, bringing security updates with them. As usual with these updates, there are no new features.

Windows 10 versions 1909 and 1903 are receiving KB4556799 (opens in new tab). Here's a look at the highlights:

  • Updates to improve security when using Internet Explorer and Microsoft Edge.
  • Updates to improve security when using input devices such as a mouse, keyboard, or stylus.
  • Updates for verifying usernames and passwords.
  • Updates to improve security when using Microsoft Xbox.
  • Updates to improve security when Windows performs basic operations.
  • Updates for storing and managing files.
  • Updates to improve security when using Microsoft Office products.

Windows 10 version 1809 features the exact same set of security updates as versions 1909 and 1903. Windows 10 version 1709 includes a nearly identical list of fixes, but with an extra one focusing on the security of things like printers and webcams. Here's a look at the highlights:

  • Updates to improve security when using Internet Explorer and Microsoft Edge.
  • Updates to improve security when using input devices such as a mouse, keyboard, or stylus.
  • Updates to improve security when using Microsoft Xbox.
  • Updates to improve security when Windows performs basic operations.
  • Updates for storing and managing files.
  • Updates to improve security when using external devices (such as game controllers, printers, and web cameras)

Finally, Windows 10 versions 1703 and 1607 largely include the same highlights as later builds. For more, you can find the full list of fixes for each release at Microsoft's support site (opens in new tab). Otherwise, these cumulative updates are available via Windows Update now.
