Microsoft releases Windows 10 build 18363.535, 17763.xxx - here's what's new

Today is Patch Tuesday, the second Tuesday of the month in which Microsoft releases updates for all supported versions of Windows 10. These updates are mandatory, so if you don"t choose to install them now, they"ll be installed automatically at some point. Normally, Microsoft released optional updates in the middle of the month, but that didn"t happen this time, oddly enough.

If you"re on Windows 10 version 1903 or 1909, you"ll get KB4530684, bringing the build number to 18362.535 or 18363.535, respectively. You can manually download it here, and there"s one highlight:

  • Updates to improve security when Windows performs basic operations.

Here"s the full list of fixes:

  • Addresses an issue that might cause error 0x3B in cldflt.sys on some devices.
  • Addresses an issue that might prevent you from creating a local user account using the Input Method Editor (IME) for Chinese, Japanese, or Korean languages. This issue occurs when setting up a new Windows device during the Out of Box Experience (OOBE).
  • Security updates to Windows Virtualization, Windows Kernel, the Microsoft Scripting Engine, and Windows Server.

Those on the Windows 10 November 2018 Update, or version 1809, will get KB4530715, bringing the build number to 17763.914. You can manually download it here, and these are the highlights:

  • Updates to improve security when Windows performs basic operations.

This one also has several known issues:

Symptom Workaround
Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_ IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

Do one of the following:

  • Perform the operation from a process that has administrator privilege.
  • Perform the operation from a node that doesn’t have CSV ownership.
Microsoft is working on a resolution and will provide an update in an upcoming release.
After installing KB4493509, devices with some Asian language packs installed may receive the error, "0x800f0982 - PSFX_E_MATCHING_ COMPONENT_NOT_FOUND."
  1. Uninstall and reinstall any recently added language packs. For instructions, see Manage the input and display language settings in Windows 10.
  2. Select Check for Updates and install the April 2019 Cumulative Update. For instructions, see Update Windows 10.

When setting up a new Windows device during the Out of Box Experience (OOBE), you might be unable to create a local user when using Input Method Editor (IME). This issue might affect you if you are using the IME for Chinese, Japanese, or Korean languages.

Note This issue does not affect using a Microsoft Account during OOBE.

To mitigate this issue, set the keyboard language to English during user creation or use a Microsoft Account to complete OOBE. You can set the keyboard language back to your preferred language after user creation. Once the OOBE is done and you are at the desktop, you can rename the current user using these instructions. If you prefer to create a new local user, see KB4026923.
