Ahead of the October 2019 Patch Tuesday, Microsoft is now rolling out update KB4524147 for devices running Windows 10 version 1903, May 2019 Update, to address two critical problems.

KB4524147 bumps the version number to build 18362.388, and according to the company, it includes an important security issue with Internet Explorer scripting engine and fixes an intermittent issue with the print spooler service that may cause print jobs to fail.

In addition, build 18362.388 addresses an issue that may result in an error when you install Features On Demand (FOD), such as .Net 3.5. The error is, “The changes couldn’t be completed. Please reboot your computer and try again. Error code: 0x800f0950.”

Microsoft is also releasing the same fixes for older versions of Windows 10, including for version 1809 as KB4524148 (build 17763.775), version 1803 as KB4524149 (build 17134.1040), and older versions:

  • Version 1709: KB4524150 (build 16299.1421).
  • Version 1703: KB4524151 (build 15063.2079).
  • Version 1607: KB4524152 (build 14393.3243).
  • Version 1507: KB4524153 (build 10240.18335).

Finally, if you’re in the Release Preview ring of the Windows Insider Preview testing the version 1909, Microsoft is also making available KB4524147 to address the same issue and bumping the version number to build 18363.388.
