## What it is
UIforETW is a Windows GUI application for recording and managing ETW (Event Tracing for Windows) traces, making deep performance investigations easier for developers and non-developers alike. It wraps xperf/WPT functionality, works around ETW bugs, records contextual data like CPU temperature and user input, and manages traces with editable notes.

## Use cases
- record ETW traces on Windows without batch files or wprui
- diagnose Windows performance problems with xperf tracing
- let non-developer users capture traces for remote performance analysis
- manage and annotate a collection of recorded ETW traces
- record CPU temperature and input data alongside performance traces
- fix symbol loading issues when analyzing ETW traces

## When to choose
- you need an easy GUI for recording ETW/xperf traces on Windows
- you want trace management with notes and categorization
- you need to work around known WPT/ETW bugs during trace recording

## When to avoid
- you need a cross-platform profiling tool
- you want actively maintained software from this specific archived repo (use randomascii/UIforETW instead)
- you only need Linux or macOS performance tracing

## Facets
- artifact type: application
- maturity: maintenance
- function: monitoring, tracing, developer-tools
- domain: performance, developer-tools, windows
- platform: windows
- tags: etw, xperf, profiling, trace-recording, windows-performance-toolkit, wpa
