Do you see a slow performance from your Secured-core PC enabled Latitude or Precision notebook?

 

Secured-core PC: Devices with Hypervisor Enforced Code Integrity (HVCI)/Virtualization Based Security (VBS) enabled.

Your Secured-core PC may show reduced performance as compared to the same device without HVCI/VBS enabled. Devices with HVCI/VBS enabled have been shown to have increased boot times, shutdown times, app launch times, and entering/exiting sleep/suspend.

You can confirm whether Hypervisor Enforced Code Integrity (HVCI)/Virtualization Based Security (VBS) is enabled on your system by checking either of the following methods:

  • Windows 10 System Information App => System Summary => virtualization-based security Services Configured & virtualization-based security Services Running (MSINFO32.exe)

  • Windows 10 Settings => Update & Security => Windows Security => Device Security => Core Isolation Details

If the performance impact is too large, HVCI/VBS can be disabled via one of the methods in the following Microsoft document:
