Your computer gets slower over time not because it wears out, but because every application you install treats your system like a personal resource it can borrow whenever it wants. Background programs are one of the most fixable performance problems — and almost nobody addresses them.
THE USUAL SUSPECTS
- Cloud sync clients — OneDrive, Dropbox, Google Drive actively uploading and checking files.
- Antivirus real-time scanning — Essential, but some AV products consume 15-25% CPU continuously.
- Browser helper processes — Chrome, Edge, and others install update helpers that run at startup whether you open the browser or not.
- Manufacturer bloatware — HP, Dell, and Lenovo all ship machines with update checkers and experience apps that serve the manufacturer, not you.
- Old software you forgot about — Trial software from 2020, utilities for hardware you no longer own — potentially all still loading at boot.
💡 Windows 10/11: Task Manager > Startup tab. Sort by "Startup impact." Disable anything you don't actively need at boot. This is free and takes 10 minutes.
