Updated: Feb 25
New year, new builds. We've just shipped updates to three FireDaemon products: Pro 6.3.5, Fusion 8.1.6, and Zero 4.0.8. Pro gets the lion's share of changes this round; some genuinely useful new features; while Fusion and Zero pick up maintenance updates to keep everything current. Here's the rundown.
FireDaemon Pro 6.3.5
If you're not familiar, FireDaemon Pro turns any Windows program into a managed Windows service; with scheduling, preconditions, lifecycle control, and tight SCM integration. This release rolls up everything from 6.2.5 through 6.3.5, and there's a lot in here.
Service Auditing
This is the headline feature. You can now:
Toggle service system auditing via local or domain-wide Group Policy via the Global Options dialog
Watch audit events in real time with a new Security Audit Monitor in the GUI.
Query the SACL (System Access Control List) of any service from the CLI.
If you're in a compliance environment (SOC 2, ISO 27001, CIS), this gives you a proper audit trail. Service CRUD (Create, Read, Update, Delete) operations also log to the Windows Event Log now; including which user account triggered the action; and those entries show up in the GUI Log Monitor too.
Bulk Password Rotation
You can now update service account passwords in bulk via the GUI or CLI. If you've ever had to rotate credentials across 50 services one at a time during a change window, you know why this matters.
dMSA Support (Server 2025)
Pro now supports Delegated Managed Service Accounts (dMSA); the new credential type in Windows Server 2025 that lets AD handle password rotation with fine-grained delegation. If you're deploying Server 2025, this means one less thing to manage manually when standing up services under domain accounts.
It's Faster
Service definitions open 3x faster for editing. That's it. If you manage a lot of services, you'll notice immediately.
GUI Improvements
The UI got a solid polish pass:
Larger fonts for high-DPI displays.
Tool tips with technical content (paths, commands) now render in Consolas; much easier to read.
Colour fixes across dark/light theme switching, dialogs, and list controls.
Focused input fields get a clean red underline accent.
"Switch to Session 0" is hidden on Windows 11 24H2+ where it's no longer relevant.
Bug Fixes
Some of these were genuinely annoying, so worth calling out:
Those spurious "service didn't respond in a timely fashion" messages when stopping or restarting services? Gone.
The Save button staying greyed out after editing environment variables, event programs, or dialog responders? Fixed.
UI crash when restarting a service with its Resource Monitor open? Fixed.
Recovery and Pre-Shutdown delays not saving when a "Restart" or "Reboot" failure action was set? Fixed.
Failure recovery commands for Windows Services not saving? Fixed.
Unresponsive UI when monitoring a service with a process tree? Fixed.
Security access permission restrictions corrected for users.
Failed service definition imports no longer get silently saved.
Logging
A few useful additions for troubleshooting:
The final resolved program path is now logged when it differs from what you configured (e.g. due to NTFS reparse points/junctions). Helpful when something isn't running from where you think it is.
Better Windows Event Log entries when a program fails to start.
Debug log now captures messages for console programs configured without a console to receive Ctrl-C.
FireDaemon Fusion 8.1.6
FireDaemon Fusion is the web-based console for managing Pro remotely; create, edit, start, stop, and monitor services from any browser, across multiple machines. It also has a RESTful JSON API if you'd rather script it.
8.1.6 is a maintenance release: updated tool chain and ships with FireDaemon OpenSSL 3.6.1. If you're jumping from an older 8.1.x build, you'll also pick up the recent TLS overhaul; TLS 1.2 is deprecated, TLS 1.3 with quantum-safe hybrid key exchange is the default, non-RSA key support is improved, HTTP automatically redirects to HTTPS, and the TLS config UI has been redesigned with proper error reporting.
FireDaemon Zero 4.0.8
FireDaemon Zero gives you interactive access to the Session 0 desktop — the isolated session where services run. If you need to interact with a service GUI, launch a PowerShell or Command Prompt on Session 0, or grab a screenshot of what's happening down there, Zero is how you do it.
4.0.8 is a maintenance release with an updated tool chain to ensure Windows compatibility.
How They Fit Together
Quick recap for anyone new: Pro runs and manages your services. Fusion lets you manage them remotely via browser or API. Zero gives you eyes and hands on Session 0 when you need them. They work independently, but together they cover the full spectrum of Windows service management.
Downloads
All three are available now with 30-day free trials. Existing FireDaemon Pro 6, Fusion 8, and Zero 4 customers and customers with Software Assurance subscriptions get these updates free.
