EventLogExpert

A Windows Event Log viewer for tech support and IT professionals.


Key features

• Opens .evtx files via File → Open, drag-and-drop, or by loading every .evtx in a folder in one step. Folders can also be passed at launch as command-line arguments.
• Combined view interleaves events from any mix of file and live logs by time across multiple machines.
• Configurable event-table columns (visibility, ordering, sort) with per-row highlight colors driven by your filters.
• Filter pane with Basic (property × operator) filters, predicates joined with AND / OR, Date filter, Advanced filter expressions, and Exclusion filters.
• Filter Library with saved single filters, named filter sets, favorites, tag-based organization, automatic tracking of recently-applied filters, plus library-wide import / export and per-filter-set export.
• Live event channels with auto-discovery (admin-only channels disabled when not elevated), Continuously Update, and a Load New Events buffered mode.
• Provider Databases — load .db files captured on another machine so its .evtx files resolve descriptions and task categories correctly.
• In-line description previews in the table; on-demand event XML in the Details pane.
• Configurable Ctrl+C copy mode (Default, Simple, XML, Full); System / Light / Dark theme.
• In-app Release Notes and Debug Log viewer; opt-in pre-release update channel.

Quick Start

Download the EventLogExpert_{version}_x64.appinstaller (or the matching EventLogExpert_{version}_x64.msix) from the latest release and run it: .

The .appinstaller declares its dependency on the Windows App Runtime (currently Microsoft.WindowsAppRuntime.1.7.msix, also published in the same release) so App Installer fetches the runtime automatically on a clean machine. Updates are checked on launch.

If you'd rather install the runtime manually first, grab Microsoft.WindowsAppRuntime.1.7.msix from the release and install it with:

Add-AppxPackage $home\Downloads\Microsoft.WindowsAppRuntime.1.7.msix

Then install the app:

Add-AppxPackage $home\Downloads\EventLogExpert_{version}_x64.msix

First time setup
