(1 Rating)
AppControl is a free advanced Task Manager for Windows with full history. Scroll back through days of system activity to see exactly what spiked your CPU, filled RAM, maxed the GPU or disk, or overheated your PC, with CPU and GPU temperature tracking over time. Built-in privacy monitoring reveals which apps accessed your webcam, microphone, or location, plus hidden installs and background tasks. Go beyond End Task: permanently disable problem apps, block entire publishers with one click, and build custom rules that stay enforced. Real-time alerts flag new or unusual apps and privacy access the moment they happen. Every process gets a plain-language description, so you can skip the web search. An optional open-source MCP extension connects Claude, Cursor, or other AI tools so you can ask about your PC's activity in plain English, and a CLI is included for power users. Lightweight (20 MB), free, and built to replace Task Manager on every PC you manage.
