KB4534293 Known Issues 

Here are some of the known bugs on this security patch –

SymptomWorkaround
With build 17134.1246, while carrying out some specific operations on files or folders that are on a Cluster Shared Volume (CSV) may get failed. At this moment, you may experience an error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. For example – rename. It basically occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

To fix this, try one of the following –

  • Login as an Admin first then only perform such tasks.
  • Carry out the operation using a node that doesn’t require CSV ownership. 

The team is working on a resolution. It may provide an update in a forthcoming release.

While setting up a new Windows device, several users report being not able to create a local user. It mainly occurs during OOBE with enabled Input Method editor. This bug appears largely on IMEs for languages like – Korean, Japanese or Korean.  

Note: This issue doesn’t interrupt using a Microsoft Account during OOBE.

In order to lessen this problem, you need to set the keyboard language to English during user creation or use a Microsoft Account to complete OOBE. You can also set the keyboard language back to your favored language after user creation. When the OOBE is completed and you are at your desktop screen, you can rename the current user using this link. However, if you prefer to create a new local user, open KB4026923.

The company is still working on a workaround. According to them, they will provide an update in the forthcoming release.
