Windows 11 looks sleek, modern, and slightly obsessed with putting everything in the center of your screen. Underneath the polished design, though, there are dozens of default settings that are… less than ideal.
Some slow down your system. Some collect more data than you’d like. Others just make everyday tasks unnecessarily annoying. The good news is that a few smart tweaks can dramatically improve performance, privacy, and usability.
This guide walks you through the most important Windows 11 settings you should change immediately—whether you’re setting up a new PC or trying to make your current one less frustrating.
1. Turn Off Unnecessary Startup Apps
Startup apps are one of the fastest ways to make a powerful computer feel slow.
Why It Matters

- Go to Apps → Startup
- Toggle off apps you don’t need at startup
What to Disable
- Chat apps
- Game launchers
- Cloud tools you rarely use
Keep only essential apps enabled.
2. Disable Background Apps

Background apps drain battery, consume memory, and can slow performance.
How to Change It
- Go to Settings → Apps → Installed Apps

Out of the box, Windows 11 collects a generous amount of data.

Disabling unnecessary startup apps, turning off background app permissions, and reducing visual effects typically deliver the biggest performance gains.
