Issues with network adapters on Windows 10 caused by Check Point Endpoint Security Client self-protection Technical Level
Symptoms
  • VPN Blade in Endpoint Security Client stops working after upgrading Windows OS to Windows 10 Version 1607 (Anniversary Update) and above.

  • All the network adapters are removed from the Windows 10 computer after performing the "Network reset" operation.

  • Installation/upgrade of additional VPN Client on the Windows 10 Version 1607 (Anniversary Update and above) computer with already installed Endpoint Security Client either crashes the entire computer, or fails with:

    There is a problem with this Windows Installer package.
    A program run as part of the setup did not finish as expected.

    Example for Cisco AnyConnect Secure Mobility Client:
  • %WinDir%\internet logs\osfwlog.txt file (per sk65071) during the aforementioned operations shows that Windows 10 process svchost.exe delete operation is blocked by the Endpoint Security Client:

    HH:MM:SS BLOCK 	Event: registry.delkey 	Process: svchost.exe[PID]  [0] (RULES)
    	HKCS\SERVICES\VSDATANT\PARAMETERS\ADAPTERS\{...}\...
    
  • Uninstalling the Check Point Endpoint Security Client resolves the above issues.

  • Disabling self-protection resolves the issue.

Cause

Check Point Endpoint Security Client protects itself by blocking any process from removing network adapters from the HKCS\vsdatant\Parameters\Adapters registry key.

As a result, Windows OS svchost.exe process fails to proceed and leaves the Windows OS state broken.
