Before you can fix the problem, you need to know what's causing it. Windows has a built-in data usage monitor that shows exactly which apps are consuming bandwidth.

If you are still looking for a way on how to fix Windows 11 system using too much data. BITS (Background Intelligent Transfer Service) is responsible for downloading Windows updates and other Microsoft content in the background. Users have reported that even after disabling BITS, it re-enables itself after a few days. However, you can throttle it to near zero.

This method requires Windows 11 Pro, Enterprise, or Education edition. If you have Windows 11 Home, this will not work.

1. Press Windows + R, type gpedit.msc, and press Enter

2. Navigate to:
