Set Registry Key for Windows Update

Carbon Black offers a way to set the required registry key for compatibility with a Windows update.

Prerequisites

See Windows KB 4072699.

Procedure

1. On the left navigation pane, click Settings > General.
2. Click Send Registry Key.
3. Set ALLOW REGKEY. Each Windows 3.1 sensor or later will install the registry key the next time that it checks in with the Carbon Black Cloud.
   The following reg key/value is created:

   • Key="HKEY LOCALMACHINE"Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat"
   • Value Name="cadca5fe-87d3-4b96-b7fb-a231484277cc"
   • Type="REG_DWORD"
   • Data="0x00000000"

   Note: Any user who has administrator rights on the endpoint can manually delete the registry key. Microsoft recommends that the key not be changed or deleted after it is created.
