Known Issues

Symptom 1

The post-installation of this patch may create issues on files and folders that are on a Cluster Shared Volume (CSV). You may receive an error “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)” while trying to operate simple tasks like renaming on the aforementioned files or folders. The main reason for the problem is that the operation takes place on a CSV owner mode from a process that fails to possess admin authorities.


Perform one of the below-given temporary solutions –

  • Use administrative rights to carry out the tasks.
  • Secondly, complete the operation from a node that doesn’t contain CSV ownership.

The team is working on a resolution and you will receive the same in the forthcoming release.

Symptom 2

Users might unable to create a local user when using the Input Method Editor (IME). This issue may happen while you attempt to set up a new Windows device in the Out of Box Experience (OOBE) phase. Moreover, it might also affect users using IME for Korean, Chinese, and Japanese languages respectively. However, you may note that the problem does not affect users using Microsoft Account during OOBE.


To reduce the impact of the trouble, use English as the keyboard language during user creation. Instead, you can also use a Microsoft Account to wrap up the OOBE procedure. However, after user creation, you can safely switch back the keyboard language to your preferred one. Moreover, once you are done with the OOBE and reach to the desktop, you can rename the current user.

Don’t worry about this temporary workaround as the team is working on a resolution. It will soon hit the PCs in the upcoming release.
