What Causes This?

Slow download speeds on Windows are usually caused by network congestion, background apps using bandwidth, or settings that limit how Windows handles updates and downloads. In some cases, outdated network drivers, VPNs, browser extensions, or temporary network glitches can also reduce speed. Even if your internet plan is fast, your PC may be the bottleneck if too many services are running in the background.

Common Symptoms

  • Downloads start fast, then slow down dramatically
  • Game launchers, browsers, or app stores download much slower than expected
  • Streaming works, but large files take a very long time to finish
  • Download speed improves briefly after restarting the PC or router
  • Task Manager shows other apps using network bandwidth while you download

How to Fix It Manually

  1. Check whether background apps are using your bandwidth

    • Open Task Manager with Ctrl+Shift+Esc.
    • Click More details if needed, then open the Processes tab.
    • Click the Network column to sort by bandwidth usage.
    • Close apps you do not need, especially cloud sync tools, game launchers, browsers with many tabs, and streaming apps.
  2. Pause Windows Update delivery and other downloads

    • Open Settings > Windows Update > Advanced options > Delivery Optimization.
    • Turn Allow downloads from other PCs to Off.
    • Go back to Windows Update and let any current updates finish, or pause updates temporarily if they are consuming bandwidth.
    • Also check apps like OneDrive, Steam, Epic Games Launcher, or Microsoft Store for active downloads.
  3. Restart your network connection

    • Turn off your modem and router for 30 seconds, then power them back on.
    • Restart your PC.
    • If you use Wi-Fi, move closer to the router or switch to a wired Ethernet connection if possible. This often gives more stable download speeds.
  4. Disable VPN, proxy, or browser extensions temporarily

    • If you use a VPN, disconnect it and test the download again.
    • To check proxy settings, go to Settings > Network & internet > Proxy and make sure an unwanted proxy is not enabled.
    • In your browser, disable download-related extensions, ad blockers, or privacy tools one at a time to see if one is slowing transfers.
  5. Reset the network adapter

    • Right-click the Start button and select Device Manager.
    • Expand Network adapters, right-click your active adapter, and choose Disable device.
    • Wait a few seconds, then right-click it again and choose Enable device.
    • If speeds are still poor, right-click the adapter, choose Update driver, then select Search automatically for drivers.
  6. Run Windows Network Reset if the problem continues

    • Open Settings > Network & internet > Advanced network settings > Network reset.
    • Click Reset now.
    • Your PC will restart, and Windows will reinstall network adapters and reset networking components.
    • After rebooting, reconnect to Wi-Fi and test your download speed again.
