Improve Internet Speed in Windows 10: 12 Fixes
If your Windows 10 PC feels slower online than it should be, the fix is usually a combination of system settings, driver updates, and network configuration—not a new router. This article walks you through the most effective, safe ways to speed up your internet connection on Windows 10, from disabling bandwidth-hogging features to updating drivers and tweaking DNS settings.
Why Windows 10 Can Feel Slower Than Other Devices
Windows 10 runs many background services by default—telemetry, updates, OneDrive sync, and app notifications—all of which can consume bandwidth without you noticing. Unlike a phone or a game console, Windows is a full multitasking OS, so it’s normal for it to use more network resources in the background. That doesn’t mean you’re stuck with it; you can control most of these processes.
Another common reason is driver or firmware issues. An outdated network adapter driver can limit your connection to a slower standard (like 802.11g instead of 802.11ac) or cause packet loss. Windows Update often installs generic drivers that work but aren’t optimized for your hardware.
Before You Start: Measure Your Baseline
You can’t know if a fix worked unless you measure first. Use a reliable speed test site (like Speedtest.net or Fast.com) and note your ping, download, and upload speeds. Run the test a few times at different times of day to get an average. Also, check what your ISP promises for your plan—if you’re already getting close to that, the issue is likely elsewhere (router placement, Wi-Fi interference, or your ISP’s network).
Keep a note of your results. After each change below, run the test again and compare. This will tell you which fix actually helped.
Quick Wins: Settings to Change Right Now
These are the simplest changes, and they often have the biggest impact:
- Pause Windows Updates temporarily: Go to Settings > Update & Security > Windows Update > Advanced options and choose “Pause updates� for a week or two. Updates can download large files in the background, slowing everything else.
- Turn off “Delivery Optimization�: In the same Advanced options screen, click “Delivery Optimization� and turn off “Allow downloads from other PCs.� This feature uses your bandwidth to send updates to other Windows users on the internet.
- Disable OneDrive sync (if you don’t use it): Right-click the OneDrive cloud icon in the system tray, go to Settings, and pause syncing or sign out. If you use OneDrive, you can set it to sync only during idle hours.
- Close background apps: In Settings > Privacy > Background apps, turn off “Let apps run in the background� or selectively disable apps you don’t need. Many apps (like Mail, Weather, or Xbox) refresh in the background, using data.
Update Your Network Adapter Driver (The Most Overlooked Fix)
An outdated or wrong driver can throttle your Wi-Fi or Ethernet connection. Here’s how to update it:
- Press Windows + X and select Device Manager.
- Expand Network adapters.
- Right-click your Wi-Fi or Ethernet adapter and select Update driver.
- Choose Search automatically for updated driver software. If Windows doesn’t find anything, go to your laptop or motherboard manufacturer’s website and download the latest driver from there (they often have newer versions than Windows Update).
- After installing, restart your PC.
If you’re on Wi-Fi, also check the adapter’s advanced properties (right-click adapter > Properties > Advanced tab). Look for settings like “802.11n/ac/ax mode� and make sure it’s set to the highest supported mode. You can also set “Power Saving Mode� to “Maximum Performance� to prevent Windows from powering down the adapter to save battery.
Disable Bandwidth-Limiting Features
Windows 10 has a few features that are designed to limit bandwidth for various reasons, but you can turn them off:
- Background apps: As mentioned, disable them in Privacy settings.
- Peer-to-peer update sharing: Already covered in Delivery Optimization.
- Windows Update bandwidth limit: In Settings > Update & Security > Windows Update > Advanced options > Delivery Optimization > Advanced options, you can set a percentage limit for background and foreground update bandwidth. Set it to 100% if you want updates to use full speed (but they will compete with your other traffic).
- Network throttling (Windows 10’s internal QoS): There’s a Group Policy setting that can limit network traffic for certain apps. To disable it, press Windows + R, type
gpedit.msc(only available on Pro/Enterprise), and navigate to Computer Configuration > Administrative Templates > Network > QoS Packet Scheduler. Set “Limit reservable bandwidth� to “Enabled� and set the limit to 0%. This is not a magic fix—Windows only uses this for specific apps—but it can help in some cases.
Change Your DNS Server (Often Speeds Up Browsing)
Your ISP’s DNS server can be slow, causing delays when you type a website address. Switching to a faster, public DNS server can reduce that delay. Here’s how:
- Open Control Panel > Network and Internet > Network and Sharing Center.
- Click your connection (Ethernet or Wi-Fi) and then Properties.
- Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
- Choose Use the following DNS server addresses and enter a public DNS like Cloudflare (1.1.1.1 and 1.0.0.1) or Google (8.8.8.8 and 8.8.4.4).
- Click OK and restart your browser.
This won’t increase your raw download speed, but it can make page loading feel snappier and reduce lag in online games that rely on name resolution.
Fix Wi-Fi Issues (If You’re on Wireless)
If you’re on Wi-Fi, your location relative to the router is critical. Walls, metal objects, and distance all weaken the signal. Try these:
- Move closer to the router (or move the router to a central, elevated spot).
- Change the Wi-Fi channel in your router’s settings (use a channel scanner to find the least congested one).
- If your router supports 5 GHz, connect to that band instead of 2.4 GHz—it’s faster and less congested, though it has shorter range.
- Make sure you’re not using a USB 3.0 device near your Wi-Fi adapter; it can cause interference.
If you’re on Ethernet, check the cable—a damaged or low-quality cable can cause slowdowns. Try a different cable or port on the router.
Frequently Asked Questions
Why is my internet slow on Windows 10 but fast on my phone?
Your phone might be using a different band (5 GHz vs 2.4 GHz), or your Windows PC may have background processes (updates, OneDrive) consuming bandwidth. Also, the Wi-Fi adapter in your PC might be older or have a weak signal. Try the driver update and DNS change first.
Will disabling Windows Update speed up my internet?
It can, especially if a large update is downloading in the background. But it’s not a permanent solution—you should let updates install eventually for security. Pausing for a week or two is fine if you’re in the middle of something important.
Does changing DNS actually improve download speed?
No, DNS only affects how quickly your PC resolves domain names to IP addresses. It won’t increase your raw download speed, but it can reduce the time it takes to start a download or load a webpage.
Is it safe to disable background apps?
Yes, disabling background apps won’t harm your system. Some apps (like email) may not refresh until you open them, but that’s fine. You can always re-enable them later.
My internet is still slow after all these fixes. What else can I do?
Run a malware scan (Windows Defender is built-in), check for large downloads in your browser (or reset your browser), and consider a network reset: Settings > Network & Internet > Status > Network reset. This reinstalls your network adapters and clears settings. If nothing helps, the issue may be your ISP or router—contact them or try a different device to confirm.
