Symptom Workaround

You may receive the following error while performing certain operations like renaming of files or folders. This occurs primarily if you are on a Cluster Shared Volume and try the above operations on a CSV owner node without possessing Administrative privileges.


To fix this anomaly, try any of these operations- 

  • Execute this operation using a Process that does have the administrator privilege. 
  • Carry out the functions using a node that doesn’t require CSV ownership.  

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

The company is pretty conscious of the fact that some PCS simply stuck and causes Black Screen during the first logon after installing the patch update.

All you require is to hold down the Ctrl+ Alt+ Delete keys combinations and press the Restart button under the Power option. 

Following the above tweak, your PC should now reboot normally.

Devices that use PXE images from WDS or SCCM may fail on the following error- 

“Status: 0xc0000001, Info: A required device isn’t connected or can’t be accessed”

  • PXE – Preboot Execution Environment
