Windows Update Improvements
Microsoft has released an update directly to the Windows Update client to improve reliability.

Known issues in this update
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." |
- Uninstall and reinstall any recently added language packs. For instructions, see Manage the input and display language settings in Windows 10.
- Select Check for Updates and install the April 2019 Cumulative Update. For instructions, see Update Windows 10.
Note If reinstalling the language pack does not mitigate the issue, reset your PC as follows:
- Go to the Settings app > Recovery.

Microsoft is working on a resolution and will provide an update in an upcoming release. |
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.
Microsoft is working on a resolution and will provide an update in an upcoming release. |
