Tip 4. Disable Background Apps and Startup Programs

Even powerful gaming PCs can lose performance when too many applications are running in the background. Programs that launch automatically during startup continue using CPU, RAM, disk, and network resources even if you are not actively using them. Disabling unnecessary startup apps and closing background processes can free valuable system resources, helping you optimize Windows 11 for gaming and maintain smoother gameplay with fewer interruptions.

To Disable Startup Apps and Close Background Processes:

Step 1. Press Windows + I to open Settings.

Step 2. Navigate to Apps > Startup.

Step 3. Windows displays all apps that launch when your computer starts.
