Immediate Fix: Resetting Windows Update and Proxy Settings
The 0x80244017 error on Windows Server 2022 typically indicates an authentication issue between the server and the Update gateway. This is most often caused by proxy server interference or corrupted update cache files.
The fastest solution is to reset the WinHTTP proxy and restart the update services. Open PowerShell or Command Prompt as an Administrator and execute the following commands:
netsh winhttp reset proxy
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
After running these commands, restart your server and attempt the installation or update again. This clears the local cache and forces the system to re-establish a direct connection to Microsoft servers.
Technical Explanation
Error 0x80244017 translates to WU_E_PT_HTTP_STATUS_DENIED. In the context of Windows Server 2022, this means the HTTP request to the Windows Update servers was rejected, usually because of a proxy requiring authentication that the system account cannot provide.
This error frequently appears in environments using Windows Server Update Services (WSUS) or strict corporate firewalls. If the system attempts to use a user-level proxy for a system-level update task, the handshake fails.
| Component | Common Failure Point | Resulting Behavior |
|---|---|---|
| WinHTTP Proxy | Authentication mismatch | Blocks background update traffic |
| WSUS Server | IIS Configuration | Denies anonymous access to update metadata |
| SoftwareDistribution | File corruption | Causes hash mismatches and 403/401 errors |

Alternative Methods
Method 1: Direct Registry Modification
If your server is wrongly trying to contact a non-existent WSUS server, you can force it to check online by modifying the registry. Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
Set the value of UseWUServer to 0. This tells Windows Server 2022 to ignore the local WSUS configuration and go directly to the Microsoft Update cloud. Restart the Windows Update service after making this change.
Method 2: Manual Installation via Microsoft Update Catalog
If the error persists during a specific Cumulative Update installation, you can bypass the Update agent entirely. Identify the KB number that is failing (e.g., KB5012345).
Visit the Microsoft Update Catalog website and search for the KB number. Download the .msu file specifically for Windows Server 2022 and run the installer manually. This method circumvents the 0x80244017 communication error.
Method 3: Configure TLS Settings
Windows Server 2022 requires secure communication. Ensure TLS 1.2 is enabled and active. Sometimes, older environments have restricted crypto-providers that block the modern update handshake. Ensure your firewall allows traffic to *.download.windowsupdate.com on port 443.
