A browser that won’t open pages or behave correctly is frustrating; the most common cause is network or software misconfiguration. If your Browser doesn’t work in Windows 10, this article walks you through the likely causes and clear fixes so you can get back online quickly.
You’ll learn the top 10 reasons browsers fail on Windows 10 (network problems, DNS, proxy/VPN, extensions, firewall/antivirus, drivers, malware, corrupted browser files, system file errors, and TLS/date issues) and step-by-step solutions — commands, menu paths, and practical tips for each.
Key Takeaway
The fastest reliable fix is to verify your network first (reboot router, run Windows Network Troubleshooter, and flush DNS), then combine basic browser troubleshooting (disable extensions, reset or reinstall the browser) with system-level fixes (run sfc /scannow, DISM, update network drivers). That sequence resolves most “browser doesn’t work” issues in Windows 10.

Detailed Fixes for “Browser doesn’t work in Windows 10”
H3: 1. No network or intermittent internet
Why it causes the problem
- If your PC isn’t connected to the internet or the connection drops, the browser can’t load pages. This is the most common and simplest cause.
Step-by-step solution
- Reboot your modem and router (unplug for 30 seconds, then plug back in).
- On your PC, open Settings > Network & Internet > Status and run Network troubleshooter.
- Try these commands in an elevated Command Prompt (right-click Command Prompt and choose Run as administrator):
- ipconfig /release
- ipconfig /renew
- ipconfig /flushdns
- Temporarily connect with another method (mobile hotspot or Ethernet) to verify whether the issue is your network.
Notes
- If multiple devices fail to connect, the problem is likely your ISP or router.
- Keep router firmware updated by checking the manufacturer’s site.
H3: 2. DNS resolution failing
Why it causes the problem
- DNS translates domain names to IP addresses; if DNS is down or slow, web pages won’t resolve.
Step-by-step solution
- Flush DNS cache: open elevated Command Prompt and run ipconfig /flushdns.
- Set public DNS servers: Settings > Network & Internet > Change adapter options → right-click your adapter → Properties → double-click Internet Protocol Version 4 (TCP/IPv4) → select Use the following DNS server addresses and enter 8.8.8.8 and 8.8.4.4 (Google DNS) or 1.1.1.1 and 1.0.0.1 (Cloudflare).
- Test resolving: nslookup example.com in Command Prompt to see if DNS replies.
Tips
- Switching DNS can often improve reliability and bypass ISP DNS issues.
H3: 3. Proxy or VPN misconfiguration
Why it causes the problem
- Wrong proxy settings or a malfunctioning VPN can block or reroute browser traffic.
Step-by-step solution
- Disable proxy: Settings > Network & Internet > Proxy → turn off Use a proxy server and ensure Automatically detect settings is on.
- Disconnect VPN clients: close any VPN application or disable in the system tray. If you must use VPN, try a different server or client.
- For corporate proxies, confirm proxy credentials and address with your IT admin.
Note
- Some malware sets a malicious proxy; check settings if you didn’t configure one.
H3: 4. Browser extensions or corrupted profile
Why it causes the problem
- Extensions or a corrupted profile can prevent page loads, crash the browser, or inject scripts that break rendering.
Step-by-step solution
- Open browser in safe/incognito mode (most extensions are disabled there). If pages load, an extension is the culprit.
- Disable all extensions: in Chrome go to chrome://extensions/; in Edge go to edge://extensions/; toggle off extensions and re-enable one-by-one to find the problem.
- Reset browser settings: Chrome: Settings > Advanced > Reset and clean up > Restore settings to their original defaults. Edge: Settings > Reset settings > Restore settings to their default values.
- If reset fails, uninstall and reinstall the browser: Settings > Apps > Apps & features → select browser → Uninstall, then install the latest version from the official site. Back up bookmarks beforehand (export bookmarks).
Tip
- Export bookmarks and save passwords before uninstalling: Bookmark Manager > Export bookmarks.
H3: 5. Outdated browser or OS compatibility
Why it causes the problem
- Older browser versions may have bugs or compatibility issues with modern websites or Windows updates.
Step-by-step solution
- Update the browser: Chrome: Menu > Help > About Google Chrome (auto-updates); Edge: Menu > Help and feedback > About Microsoft Edge.
- Run Windows Update: Settings > Update & Security > Windows Update → Check for updates.
- If an update causes issues, try a different browser (Chrome, Edge, Firefox) to determine whether it’s browser-specific.
Note
- Enterprise-managed machines may block updates; contact IT if you cannot upgrade.
H3: 6. Firewall or antivirus blocking access
Why it causes the problem
- Security software may mistakenly block a browser or certain web traffic.
Step-by-step solution
- Temporarily disable third-party antivirus or firewall and test the browser.
- Allow the browser through Windows Firewall: Control Panel > System and Security > Windows Defender Firewall > Allow an app or feature through Windows Defender Firewall → click Change settings → ensure your browser is checked for Private and Public networks.
- For third-party security suites, open the app and add the browser executable (e.g., chrome.exe, msedge.exe) to exceptions.
Warning
- Re-enable security software promptly; only temporarily disable for testing.
H3: 7. Network adapter driver problems
Why it causes the problem
- Faulty or outdated drivers can cripple the network stack, causing intermittent or no connectivity.
Step-by-step solution
- Open Device Manager: right-click Start → Device Manager → expand Network adapters.
- Right-click your adapter → Update driver → Search automatically. If that fails, download the latest driver from the manufacturer website and use Browse my computer for drivers.
- If updating doesn’t help, right-click → Uninstall device (check Delete the driver software for this device if offered), then reboot to let Windows reinstall the driver.
- Run network resets: open elevated Command Prompt and run:
- netsh winsock reset
- netsh int ip reset
- reboot the PC.
Tip
- Use Ethernet to test whether Wi-Fi adapter drivers are the issue.
H3: 8. Malware or browser hijackers
Why it causes the problem
- Malware may redirect traffic, inject ads, or modify network settings (hosts file, proxy) to break browsing.
Step-by-step solution
- Run a full scan with Windows Defender: Settings > Update & Security > Windows Security > Virus & threat protection > Quick scan (choose full scan for thorough check).
- Download and run Malwarebytes (free) for a second opinion and clean-up.
- Check and reset the hosts file: open C:\Windows\System32\drivers\etc\hosts in Notepad as Administrator and ensure no suspicious entries (127.0.0.1 or blocked domains). Restore to default if needed.
- After removal, reset browser settings and change passwords for sensitive accounts.
Note
- Persistent infections may require boot-time scans or recovery media.
H3: 9. Corrupt system files or Windows Update errors
Why it causes the problem
- Corrupt system files or an incomplete update can damage networking components that browsers rely on.
Step-by-step solution
- Run System File Checker: open elevated Command Prompt and run sfc /scannow.
- If issues persist, run DISM: DISM /Online /Cleanup-Image /RestoreHealth (requires internet).
- After DISM completes, run sfc /scannow again and reboot.
- If Windows Update failed recently, go to Settings > Update & Security > Troubleshoot > Additional troubleshooters → Windows Update and run the troubleshooter.
Tip
- Keep a system restore point or backup before major updates.
H3: 10. TLS/certificate errors or incorrect date/time
Why it causes the problem
- Secure websites require accurate system time and properly enabled TLS/SSL protocols; mismatches or disabled TLS will block secure sites.
Step-by-step solution
- Check date and time: right-click the clock → Adjust date/time → enable Set time automatically and Set time zone automatically.
- Ensure TLS settings are enabled: Open Internet Options (search from Start) → Advanced tab → scroll to Security → enable Use TLS 1.2 (and TLS 1.3 if supported) and uncheck very old protocols.
- Clear browser SSL state: Internet Options > Content > Clear SSL state.
- If you see certificate errors, click the padlock in the address bar for details and verify the site certificate; avoid proceeding on unknown sites.
Note
- Some corporate environments use custom certificates—import the required CA certs if instructed.
Additional Tips: Clean Boot, Safe Mode, and Backing Up Browser Data
Clean Boot and Safe Mode
- If troubleshooting steps conflict, perform a clean boot: press Win + R, type msconfig, on the Services tab check Hide all Microsoft services, click Disable all, then go to Startup → Open Task Manager and disable startup items; reboot. This isolates third-party software conflicts.
- Safe Mode with Networking: Hold Shift while selecting Restart → Troubleshoot > Advanced options > Startup Settings > Restart → press 5 for Safe Mode with Networking. Test your browser there.
Backing up browser data
- Export bookmarks and saved passwords before resetting or reinstalling a browser:
- Chrome/Edge: Settings > Bookmarks > Bookmark manager > Export bookmarks.
- Firefox: Bookmarks > Show All Bookmarks > Import and Backup > Export Bookmarks to HTML.
- For passwords, use browser sync accounts (Google, Microsoft, Firefox Account) or export passwords via settings (may require enabling export).
When to seek professional help
- If multiple devices fail while your PC is fine, contact your ISP.
- If you suspect hardware failure, driver reinstall didn’t help, or malware persists after multiple tools, consult a professional.
FAQ
Q: Why can other apps access the internet but my browser can’t?
A: Browsers are sometimes blocked by firewall or have corrupted profiles/extensions. Temporarily disable firewall/AV, test other browsers, and reset the problematic browser.
Q: How can I test whether DNS is the issue?
A: Use nslookup example.com—if it fails to resolve or returns a timeout, try ipconfig /flushdns and switch to public DNS (8.8.8.8).
Q: Does a slow browser equal a broken browser?
A: Not always; slowness can be caused by heavy extensions, too many open tabs, a crowded cache, or poor network speed—clear cache and disable extensions first.
Q: Can resetting Windows be necessary to fix browser problems?
A: Rarely. Use resets, SFC/DISM, and clean boot first. Only consider Reset this PC or reinstalling Windows if all else fails and the system is deeply corrupted.
Q: How do I recover bookmarks and passwords if my browser won’t start?
A: If the browser profile is accessible, copy the profile folder (Chrome: %LOCALAPPDATA%\Google\Chrome\User Data\Default). Alternatively, reinstall the same browser and import the profile files or use sync services.
Conclusion
Most cases where a Browser doesn’t work in Windows 10 are solved by checking the network, flushing DNS, disabling proxies/VPNs, removing problematic extensions, and running SFC/DISM or driver updates. Follow the step-by-step fixes above in order, and you’ll resolve the majority of browser problems quickly.
