Hi, Error code C80003F9 is usually received when trying to get updates via Automatic Update. Did you? Based on my experience, this issue can be caused by the following factors: 1. The Windows Update service has been stopped. 2. Corrupted Windows Update Temporary folder. In order to narrow down the cause of this issue and resolve it, please refer to the following steps. After finishing each step, please check the result again on the Windows Update website. NOTE: Some third party programs can affect the Windows Update service. If you are running any third party applications such as Spyblocker, Internet or web accelerators (programs designed to boost the speed of the Internet connection), security or anti-virus programs (Norton, McAfee, etc.), I recommend we temporarily disable or shut them down and then try accessing Windows Update later. Please understand that we are disabling these programs only for the purpose of troubleshooting and we can re-enable these programs after we finish troubleshooting. Step 1: Verify the relevant Windows Update services ======================================= 1. Click the Start Button, in Start Search box, type: "services.msc" (without quotes) and press Enter. If you are prompted for an administrator password or confirmation, type the password or provide confirmation. 2. Double click the service "Windows Update". 3. Click on the "General" tab; make sure the "Startup Type" is "Automatic" or "Manual". Then please click the "Start" button under "Service Status" to start the service. 4. Please repeat the above steps with the "Background Intelligent Transfer Service" service. You can also temporarily stop these services, restart the computer, and then start these services again. If any service is missing or cannot be stopped or restarted, please let me know. Step 2: Rename the Windows Update Softwaredistribution folder ================================================ This problem may occur if the Windows Update Software distribution folder has been corrupted. We can refer to the following steps to rename this folder. Please note that the folder will be re-created the next time we visit the Windows Update site. 1. Close all the open windows. 2. Click the Start Button, click "All programs", and click "Accessories". 3. Right-click "Command Prompt" and click "Run as administrator". 4. In "Administrator: Command Prompt" window, type in "net stop WuAuServ" (without the quotes) and press Enter. Note: Please look at the cmd window and make sure it says that it was successfully stopped before we try to rename the folder. However, if it fails, please let me know before performing any further steps and include any error messages you may have received when it failed. 5. Click the Start Button, in the "Start Search" box, type in "%windir%" (without the quotes) and press Enter. 6. In the opened folder, look for the folder named "SoftwareDistribution". 7. Right-click on the folder, select Rename and type "SDold" (without the quotes) to rename this folder. 8. While still in the "Administrator: Command Prompt" window, type the command "net start WuAuServ" (without the quotes) in the opened window to restart the Windows Updates service. Note: Please look at the cmd window and make sure it says that it was successfully started. However, if it failed, please let me know before performing any further steps and include any error messages you may have received when it failed. If the issue persists, to clarify the issue and provide more accurate troubleshooting steps, please assist me in collecting the following information. 1. Capture a screenshot ====================== 1Press the Print Screen key (PrtScn) on your keyboard. 2Click the Start Button, type "mspaint" in the Search Bar and Press Enter. 3In the Paint program, click the "Edit" menu, click "Paste". Then click the "File" menu, and click "Save". 4The "Save As" dialogue box will appear. Type a file name in the "File name:" box, for example: "screenshot". 5Make sure "JPEG (*.JPG;*.JPEG;*.JPE;*.JFIF)" is selected in the "Save as type" box, click "Desktop" on the left pane and then click "Save". 2.Collect the System Information ============================= The System Information can provide us with more information about the current status of the system. I would like to check it for you. Please send it to me using the following steps: 1Click the Start Button, type "MSINFO32" in the Search Bar and press Enter to start System Information. 2On the popup window, on the menu bar, click "File", and click "Save", type a file name and then choose NFO as "Save as type", click "Desktop" on the left pane, and click Save. 3.Collect the WindowsUpdate.log file ================================ 1Click the Start Button, type "WindowsUpdate.log" (without the quotes) in the Search Bar and Press Enter. We will see a file named "WindowsUpdate.log" 2Now click on the "File" menu and then click on the "Save As". 3From the left panel, click "Desktop" and click the Save button. Best Regards, Dale

Dale - Just a note to say Thank you! In case anyone else stumbles across this thread...Your "Step 2" above worked like a charm. I discovered the problem when I tried to manually run an update. Whenever I would click on "Check for Updates" I would receive the C80003F9 error code. It turns out that I had not been receiving automatic updates for well over a month. -Wyrmrender Windows 7 64-bit
