How to fix error code 0x800f0926: Windows Update failure on Windows Server 2008

If you encounter error code 0x800f0926 while using Windows Update on Windows Server 2008, follow these steps to resolve it:

1. Verify your internet connection: Ensure your internet connection is reliable and functioning correctly. An unstable connection can prevent Windows Update from downloading and installing updates.
2. Use the Windows Update troubleshooter: Utilize the built-in troubleshooter in Windows Server 2008 to diagnose and resolve Windows Update issues. Navigate to Control Panel > System and Security > Troubleshoot common computer problems > Fix problems with Windows Update to run the troubleshooter.
3. Check available disk space: Confirm that your server has sufficient free disk space to accommodate updates. A full disk can hinder Windows Update from downloading and installing updates.
4. Temporarily disable antivirus software: Antivirus programs can sometimes block Windows Update. Disable your antivirus software temporarily to see if it resolves the issue.
5. Manually install updates: If Windows Update still fails, download and install updates manually from the Microsoft Update Catalog. Though time-consuming, this method may be necessary if Windows Update is not functioning correctly.
