Windows 11 Debloat for Gaming 2026

What is Windows Bloatware?

Windows 11 comes preinstalled with dozens of unnecessary apps and background services that consume RAM, CPU, and disk resources. Bloatware includes apps you'll never use (Xbox Game Bar for non-gamers, OneDrive if you don't use cloud storage), telemetry services, advertising components, and manufacturer-installed trials. Removing bloatware frees up 1-4GB RAM, reduces CPU background usage, and speeds up boot times.
