With Active Protection disabled on a Windows 10 computer, Windows Defender will enable itself automatically. This can cause CPU usage spikes during scanning and updates.

 Reasons for disabling Active Protection:
  • Software deployment
  • Trial and error testing
  • Maintenance


  • VIPRE Business
  • VIPRE Business Premium
  • VIPRE Endpoint Security
  • Windows 10 (both 32- and 64-bit)


There are a few solutions to this issue:
  • Disable Windows Defender
    Here is a link that details one way to disable Windows Defender through Registry Editor or Group Policy.
  • Enable Active Protection
    Note: This is done on a policy-by-policy basis and is the recommended setting for VIPRE


Windows Defender will enable if it detects no other active protection is enabled. This is by design in Windows 10.
