KB4493436 bugs

Thankfully, KB4493436 brought a single known issue to the table. Microsoft warns Windows 10 users that some specific operations performed on CSV may fail. 

Microsoft recommends its users to try the following workarounds to fix the bug on their systems:

  • Perform the operation from a process that has administrator privilege.
  • Perform the operation from a node that doesn’t have CSV ownership.

However, this is a temporary workaround and the company promises to address the issue in the next update.
