A little more than a week after Patch Tuesday, Microsoft is releasing cumulative updates for Windows 10 versions 1809, 1903, and 1909. The biggest news for version 1909 and 1903 is that the Redmond firm is backporting Windows Subsystem for Linux 2 (WSL2) to those versions. However, there are a long list of fixes that are also accompanying the support for WSL2.
First up is Windows 10 version 1909. The updates, as is customary for 1909 and 1903 are identical. Builds 18362.1049 and 18363.1049 are rolling out for 1903 and 1909, respectively. The knowledge base article is KB4566116 and can be manually downloaded from the Update Catalog here. Interestingly, there are no known issues in this update.
Here are the highlights of the two versions:
- Updates an issue that causes the hard drive to fill up in certain error situations.
- Updates an issue that prevents Microsoft Gaming Services from starting because of error 15612.
- Updates time zone information for the Yukon, Canada.
- Updates a visual offset issue on a touchscreen. Edits you make with a pen or finger appear in a different region than expected if the device is connected to an external monitor.
- Updates an issue that causes the Settings page to close unexpectedly, which prevents default applications from being set up properly.
- Updates an issue that prevents you from unlocking a device if you typed a space before the username when you first signed in to the device.

This cumulative update does have two known issues. Here they are:
|
Symptom |
Workaround |
|---|---|

After installing KB4493509, devices with some Asian language packs installed may receive the error, "0x800f0982 - PSFX_E_MATCHING_COMPONENT_NOT_FOUND." |
Note If reinstalling the language pack does not mitigate the issue, reset your PC as follows:
Microsoft is working on a resolution and will provide an update in an upcoming release. |
|
After installing KB4550969 or later, when using Microsoft Edge Legacy, you might receive the error,”0x80704006. Hmmmm…can’t reach this page” when attempting to reach websites on non-standard ports. Any website that uses a port listed in the Fetch Standard specification under bad ports or port blocking might cause this issue. |
To mitigate this issue, you can do one of the following:
Note The new, Chromium-based Microsoft Edge will also fail to connect to websites on non-standard ports by default. This is an expected behavior. However, you can allow sites on the affected non-standard port by using the parameter --explicitly-allowed-ports=####, where #### is the port you require. For example, when you need to access a website on port 6667, type c:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe--explicitly-allowed-ports=6667 We are working on a resolution and will provide an update in an upcoming release. |
As usual, these updates should begin downloading via Windows Update. While these aren’t the usual Patch Tuesday updates, Microsoft has resumed the optional mid-month updates, which is what these are. The addition of WSL2 on Windows 10 versions 1909 and 1903 will be a welcome addition for those that have held off on updating to version 2004.
