Symptoms
You might be experiencing this problem if you notice:
- •Windows Update shows error 0x80244022 when checking for updates
- •"We couldn't connect to the update service" message
- •Updates fail to download with connection timeout
- •Error appears after changing network or proxy settings
- •Update check takes very long then fails with this error

Common Causes
- ⚠Windows Update servers unreachable (temporary outage)
- ⚠Proxy or firewall blocking Windows Update traffic
- ⚠WSUS server configured but not accessible
- ⚠DNS not resolving Windows Update domains
- ⚠Date/time incorrect causing SSL certificate validation failure
- ⚠Metered connection settings blocking update downloads
Solutions
Solution 1: Check Network and Proxy
- 1First verify internet is working: open a website in browser
- 2If on VPN: try disconnecting VPN and checking for updates
- 3Check proxy settings: Settings → Network & internet → Proxy
- 4If proxy is configured incorrectly: turn off "Use a proxy server"
- 5For corporate networks: ensure proxy allows these domains:
- 6*.update.microsoft.com, *.windowsupdate.com, *.microsoft.com
- 7Reset WinHTTP proxy: CMD as Admin: netsh winhttp reset proxy
Solution 2: Fix WSUS Configuration
- 1If on domain/corporate network using WSUS:
- 2Registry: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
- 3Check "WUServer" and "WUStatusServer" values — must point to valid WSUS server
- 4If WSUS server is down: temporarily bypass it:
- 5Rename or delete the WindowsUpdate registry key
- 6This forces Windows to use Microsoft's public update servers
- 7After updating: restore the registry key for WSUS
- 8Contact your IT admin if WSUS server is consistently unavailable
Solution 3: Reset Windows Update
- 1If network is fine but updates still fail:
- 2CMD as Admin:
- 3net stop wuauserv
- 4del /f /s /q C:\Windows\SoftwareDistribution\*
- 5net start wuauserv
- 6Also verify date/time: Settings → Time & language → Date & time
- 7"Set time automatically" should be ON
- 8Wrong date/time causes SSL errors that look like connection failures
- 9Flush DNS: ipconfig /flushdns → try updates again
