Updates

Windows Update error codes#

When using Azure Update Manager, machines are periodically assessed. Sometimes, they may show as Not assessed under Compliance tab. As the result, HRESULT error codes show in the portal. One can usually fix updates after onboarding the machine and running the command below in the PowerShell:

Get-WindowsUpdateLog

Log file will be dumped on the Desktop. Reboot may sometimes help.

HRESULT error codes#

• 0x8024402C, 0x8024401C, 0x8024402F: indicate network connectivity rules, check Defender Firewall, in case of Azure, NSG rules.
• 0x8024402C: double-check the registry values for WUServer and WUStatusServer in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate (sometimes taken care of by GPO, reboot may help in this case).
• 0x8024500C: WU tries to check for updates in web, even though WSUS is enabled. Create a new key in the registry:
