PC Activity Monitor

PC Activity Monitor quietly records what happens on a Windows machine: keystrokes typed, applications used, periodic screenshots of the desktop. The log stays on your local disk — no cloud, no upload, no telemetry.

Legitimate uses

This tool is intended for use on machines you own or have explicit consent to monitor. Common scenarios:

• Parental supervision on a family computer used by children
• Personal audit trail — recover the paragraph you typed before Word crashed
• Forensic-style review of your own machine after suspected unauthorised access
• Research on personal computer-use patterns
• Memory aid — "what was that URL I typed last Tuesday?"

Using monitoring software on a machine you do not own — or on a person who has not consented — may violate local laws. Check before deploying.

What it captures

• Keystroke log with timestamps
• Active-window history (what application was in focus, when)
• Periodic screen captures at a configurable interval
• Optional URL log (when a browser is active)

How it stores data

All captured data is written to a folder on the same machine. Nothing is uploaded. Nothing leaves the device. The log files are plain disk files you can review at any time and delete when you no longer need them.

Features

• Configurable capture interval for screenshots
• Optional auto-start with Windows
• Password-protected configuration screen
• Local-only storage — no telemetry, no cloud upload
• Portable single executable

System requirements

• Windows 7, 8, 10, 11
• Disk space for the log files (a few MB per day at typical settings)
• Administrator rights (recommended) to install the monitor as a startup service
