What you need to know

• Microsoft shipped a new batch of cumulative updates for Windows 10 PCs today.
• The updates apply to Windows 10 versions 1809, 1903, and 1909.
• Included are a large number of fixes, including one for a Windows Hello bug that would prevent your PC from recognizing the camera.

We saw July's Windows 10 Patch Tuesday updates arrive last week, and now Microsoft is shipping out another round of them. Today, the updates are available for Windows 10 versions 1809, 1903, and 1909. There are a wide range of fixes included with each update, including one for a rather annoying Windows Hello bug.

For Windows 10 versions 1903 and 1909, the most notable fix is for Windows Hello. Previously, your PC might fail to recognize your Windows Hello camera. This build fixes that issue, hopefully getting Windows Hello back in working order for PCs on these releases.

Windows 10 versions 1903 and 1909 both receive the same list of fixes. Here's a look at what's new:
