Filter Plugfest 2024!

Hello! We are excited to announce that Plugfest 2024 is starting February 5th 2024!!

Plugfest is going to continue to be virtual for 2024! Similar to the last iteration, Plugfest 2024 will have VMs hosted on Azure in place of physical HW. Plugfest VMs will provide you access to both Windows Client and Server OS.

What is Plugfest?
The goal of Plugfest is to help you prepare your file system minifilter, network filter, or boot encryption driver for the next version of Windows by performing interoperability testing with other products.

When is Plugfest 2024?
Plugfest 2024 will take place between Monday, February 5, 2024 and Friday February 9, 2024.

Who should participate?
Independent Software Vendors (ISVs), developers writing file system minifilter drivers and/or network filter drivers for Windows.

How much does it cost?
FREE - There is no cost to attend this event.

Why should I go?
Here are four major benefits of Plugfest:

  1. The opportunity to test products extensively for interoperability with other vendors’ products and with Microsoft products. This has traditionally been a great way to understand interoperability scenarios and flush out any interoperability-related bugs.
  2. Get exclusive talks and informative sessions organized by the File System Minifilter team about topics that affect the filter driver community.
  3. Great opportunity to meet with the file systems team, the network team, and various other teams at Microsoft and get answers to your unanswered technical questions.
  4. Early exposure to new hardware innovations, that affect filter functionality.
