Known Issues on KB4525237 


Symptom Workaround

With Build 17134.1130, you may receive an error when performing certain operations, for example, rename, on files or folders.

This happens very often while using Cluster Shared Volume (CSV). Thereupon, you will observe the error message that prompts while the execution is-STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5).

It occurs since the operation does not have an administrator authorization. Also, the operation performs on the CVS owner node.

Follow anyone –

  • Perform the operation using a process that holds admin authorities.
  • Use a node that does not have CSV ownership and then perform the task.

In the upcoming release, the experts promise to release a solution as they are currently working upon this.

While configuring a new Windows device during Out of Box experience, you can’t generate a local user using IMEs. This anomaly arises primarily if you are using Input Method Editors like- Chinese, Korean or Japanese languages. 

Note: This doesn’t affect your personal Microsoft account while setting up a new device during OOBE.

Subsequently, to resolve this issue, you should try either of these two options to finish OOBE-

  1. Use Microsoft account
  2. Switch to the default (English language) on your Keyboard.

Once your PC is ready for usage, you could turn back on your local language. 

Microsoft experts are currently working on a resolution and will provide an update in a future release.
