Postup řešení

1 Press Windows key + I to open Settings, go to 'Network & Internet', then 'Proxy'.
2 Under 'Manual proxy setup', check if 'Use a proxy server' is toggled ON. If it is, and you don't need it, turn it OFF. If you do need it, ensure the address and port are correct.
3 Press Windows key + R, type 'inetcpl.cpl', and press Enter. This opens Internet Properties. Go to the 'Connections' tab and click 'LAN settings'.
4 Uncheck 'Use a proxy server for your LAN' if it's checked and you don't use a proxy. Click OK.
5 If you're on a corporate network, you may need to use a script or automatic configuration. Check with your IT admin.
6 Temporarily disable your third-party firewall or antivirus to see if it's blocking. If it is, add Windows Update to the allowed list.
7 Restart your PC and try Windows Update again.

First, check if you can access the internet normally. Open a web browser and go to https://www.microsoft.com. If you can't, your internet connection is the issue.
If you can, the problem might be with proxy settings. Press Windows key + R, type 'inetcpl.cpl', and press Enter. This opens Internet Properties. Go to the 'Connections' tab and click 'LAN settings'.
In the 'Local Area Network (LAN) Settings' window, uncheck 'Use a proxy server for your LAN' if it's checked. Also, ensure 'Automatically detect settings' is checked. Click OK to save.
If you're on a corporate network, you may need to use a proxy. In that case, check with your IT department for the correct proxy settings and enter them in the same window.
Next, check your firewall settings. If you have a third-party firewall, temporarily disable it to see if that resolves the issue. If it does, add Windows Update to the firewall's allowed list.
Also, reset the Windows Update components using the command prompt. Open Command Prompt as administrator (Windows key + X → 'Terminal (Admin)') and run the following commands: 'net stop wuauserv', 'net stop bits', 'net stop cryptsvc', then rename the SoftwareDistribution and catroot2 folders, and restart the services. This can clear any corrupted settings.
Finally, restart your PC and try Windows Update again.

First, check if you have a proxy configured. Press Windows key + I to open Settings, go to 'Network & Internet', then 'Proxy'. Under 'Manual proxy setup', ensure that 'Use a proxy server' is turned off. If it's on, you may need to turn it off temporarily to see if that fixes the issue.
If you're on a corporate network, you might need to use the proxy. In that case, ensure the proxy settings are correct. You can also add Windows Update domains to the proxy bypass list. Common domains: '*.update.microsoft.com', '*.windowsupdate.com', '*.download.windowsupdate.com', '*.delivery.mp.microsoft.com'.
Check your firewall settings. If you're using Windows Defender Firewall, go to Control Panel → System and Security → Windows Defender Firewall → Allow an app or feature through Windows Defender Firewall. Ensure 'Windows Update' is checked for both Private and Public networks.
If you're using a third-party antivirus with a firewall, temporarily disable it to see if it's blocking. If it is, add exceptions for Windows Update.
You can also reset the Windows Update components using the 'netsh' command. Open Command Prompt as administrator and run 'netsh winhttp reset proxy'. This clears any proxy settings that might be causing issues.
Another method is to use the Windows Update Troubleshooter: Settings → System → Troubleshoot → Other troubleshooters → Windows Update → Run.
If you're on a VPN, disconnect and try again. Sometimes VPNs interfere with Windows Update.
