Hot Fix and Patch History

When the Apex One server deploys hot fix or patch files to Security Agents, the agent program records information about the hot fix or patch in Registry Editor. You can query this information for multiple agents using logistics software such as Microsoft SMS, LANDesk™, or BigFix™.


This feature does not record hot fixes and patches that are deployed only to the server.

Information is stored in the following keys:

  • HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\ CurrentVersion\HotfixHistory\<Product version>

  • For computers running x64 type platforms:

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TrendMicro\ PC-cillinNTCorp\CurrentVersion\HotfixHistory\<Product version>

Check for the following keys:

  • Key: HotFix_installed

    Type: REG_SZ

    Value: <Hot fix or patch name>

  • Key: HotfixInstalledNum

    Type: DWORD

    Value: <Hot fix or patch number>
