LogWindowAtPoint is a lightweight, portable Windows utility developed by IT expert Uwe Sieber. Its primary purpose is to log and identify mysterious, flashing, or randomly popping up windows that quickly open and close on your screen.
It is highly effective for tracking down adware, misbehaving background tasks, or rogue scripts that steal focus for a split second before vanishing. Key Features
Targeted Monitoring: You drag a bullseye target over a specific pixel or area on your screen. The tool will continuously monitor that specific point.
Detailed Logging: When a window intersects with that monitored point, the software captures and displays its details, including: Executable file name (.exe) Process ID (PID) Window Class name Window Title/Caption
Command Line Automation: Starting from version 1.1, you can pass specific screen coordinates and polling intervals via the command line (e.g., LogWindowAtPoint 5 1270 15 to check coordinates every 15 milliseconds). How to Use It
Download the tool directly from the Uwe Sieber Tools for Windows Page.
Extract the ZIP file and run the application (no installation is required).
Drag the target tool to the exact area of your desktop where the annoying pop-up usually flashes.
Leave the tool running in the background. Once the window pops up again, check the application log to find out exactly what software caused it. Sister Tool
If windows flash randomly all over your screen rather than at one specific spot, you can use LogForegroundWindow (available on the same website). Instead of checking a physical coordinate, it records the details of whichever window successfully steals the Windows input focus.
Are you currently trying to troubleshoot a specific pop-up or looking for command-line configurations to automate the logging process?
