How to Stop System Data Usage in Windows 11: A Complete Guide

By / September 22, 2025

Do you feel like your Windows 11 PC is consuming too much data, even when you’re not actively browsing, streaming, or downloading? You’re not imagining it. By default, Windows 11 uses background processes for system updates, telemetry, syncing, app downloads, and cloud services, all of which contribute to data usage.

In this step-by-step guide, we’ll explain why Windows 11 uses system data, how to monitor usage, and—most importantly—how to stop unnecessary system data consumption. Whether you’re on a limited Wi-Fi plan, mobile hotspot, or slow internet connection, these tips will help you save bandwidth without breaking your system.

📌 Key Takeaways

  • Windows 11 uses system data for updates, syncing, app downloads, and diagnostics.

  • You can monitor usage through Settings or Command Prompt.

  • Enabling metered connection helps reduce background data use.

  • Turning off background apps, OneDrive, and telemetry drastically lowers system usage.

  • Advanced users can use Group Policy Editor and Registry tweaks for deeper control.

Why Does Windows 11 Use So Much System Data?

Before we jump into solutions, let’s understand what “system data usage” means.

Windows 11 consumes background data for:

  • 🔄 Windows Updates – Downloading patches, drivers, and security fixes.

  • ☁️ OneDrive Sync – Uploading and syncing files automatically.

  • 📊 Telemetry & Diagnostics – Sending data to Microsoft for analytics.

  • 🛠️ Microsoft Store Updates – Auto-updating installed apps.

  • 📧 Background Services – Mail, Calendar, Weather, etc.

While some of this is necessary, a lot of it can be controlled or disabled.

How to Check System Data Usage in Windows 11

Knowing what’s eating up your bandwidth is the first step.

Method 1: Via Settings

  1. Press Windows + I to open Settings.

  2. Go to Network & internet → Data usage.

  3. Choose your active network (Wi-Fi or Ethernet).

  4. Scroll down to see usage breakdown by app.

👉 Here you’ll notice that “System” is often one of the top data consumers.

Method 2: Using Command Prompt

  1. Press Windows + S, type cmd, and run as administrator.

  2. Enter:

    netstat -e -s

  3. This will display data packets sent and received.

This method is more technical but useful for real-time monitoring.

How to Stop System Data Usage in Windows 11 (Step-by-Step)

Let’s go through practical fixes.

1. Set Your Network as a Metered Connection

This tells Windows to limit background data usage.

Steps:

  1. Open Settings → Network & internet.

  2. Select Wi-Fi or Ethernet → click your network.

  3. Toggle Metered connection → On.

📌 Result: Windows Update and app downloads are paused unless you allow them.

2. Disable Background Apps

Apps running in the background silently consume data.

Steps:

  1. Go to Settings → Apps → Installed apps.

  2. Select an app → Click Advanced options.

  3. Under Background apps permissions, choose Never.

Repeat for apps you don’t need running in the background.

3. Pause or Limit Windows Updates

Windows Updates are one of the biggest culprits.

Option A: Pause Updates Temporarily

  1. Go to Settings → Windows Update.

  2. Click Pause for 1 week (extendable).

Option B: Limit Update Bandwidth

  1. Open Settings → Windows Update → Advanced options.

  2. Under Delivery Optimization → Advanced options.

  3. Limit download/upload bandwidth percentage.

4. Stop OneDrive from Syncing Automatically

OneDrive uploads and downloads files in the background.

Steps:

  1. Right-click the OneDrive icon in taskbar → Settings.

  2. In Sync and backup, turn off folder sync you don’t need.

  3. Alternatively, unlink your PC from OneDrive completely.

👉 If you don’t use OneDrive, disable it from startup via Task Manager → Startup apps.

5. Turn Off Windows Telemetry & Diagnostics

Telemetry constantly sends usage reports to Microsoft.

Steps:

  1. Open Settings → Privacy & security → Diagnostics & feedback.

  2. Under Diagnostic data, choose Required only.

  3. Turn off Improve inking and typing & Tailored experiences.

This reduces background data significantly.

6. Disable Delivery Optimization

Windows sometimes uses your internet to upload updates to other PCs.

Steps:

  1. Go to Settings → Windows Update → Advanced options → Delivery Optimization.

  2. Turn off Allow downloads from other PCs.

7. Restrict Microsoft Store Auto-Updates

App updates consume data silently.

Steps:

  1. Open Microsoft Store.

  2. Click your profile icon → App settings.

  3. Toggle off App updates.

8. Use Group Policy Editor (Pro & Enterprise Users)

For advanced control over updates and telemetry:

  1. Press Windows + R, type gpedit.msc, hit Enter.

  2. Navigate to:

    Computer Configuration → Administrative Templates → Windows Components

  3. Adjust policies for Windows Update, Data Collection, and Delivery Optimization.

9. Registry Tweaks (Advanced Users)

If you’re comfortable editing the registry:

  1. Press Windows + R → Type regedit.

  2. Navigate to:

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection

  3. Modify AllowTelemetry → Set value to 0.

⚠️ Warning: Incorrect edits may cause system issues. Always back up your registry first.

10. Use Third-Party Firewalls or Data Monitors

Apps like GlassWire or NetBalancer let you track and block Windows processes from using excessive data.

Quick Fixes: Simple Habits to Save Data

  • 🔌 Disconnect Wi-Fi when not in use.

  • 🎧 Close apps like Spotify, Steam, or Cloud Drives while working.

  • ⚙️ Regularly check Task Manager → Processes for data-hungry apps.

  • 📅 Schedule large updates for unlimited networks only.

Comparison: Methods to Reduce Data Usage

Method Difficulty Effectiveness Best For
Metered Connection Easy High Everyday users
Disable Background Apps Easy Medium Limited data plans
Pause Updates Easy High Temporary relief
OneDrive Settings Easy High Cloud users
Telemetry Reduction Medium Medium Privacy-focused users
Group Policy / Registry Hard Very High Advanced users

Conclusion

Windows 11 system data usage can eat up bandwidth quickly, but with the right tweaks, you can take back control of your internet usage.

  • Start with metered connection and background app control for quick wins.
