The following article provides information and guidance on slow performance reported on Secured-core PC enabled Latitude or Precision notebooks.
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)
(Figure.1 HVCI/VBS enabled shown in Windows 10 System information)
Windows 10 Settings => Update & Security => Windows Security => Device Security => Core Isolation Details
(Figure.2 HVCI/VBS enabled shown in Windows 10 Windows Security settings)
There is no failure occurring in these systems. While working within the design limitations of Windows 10 and the system design, the reduction in performance is inherent to the behavior of HVCI/VBS. If the performance impact is too large, HVCI/VBS can be disabled via one of the methods in the following Microsoft document:
