Usually, this problem happens because DOM storage is turned off or cookie settings are too strict in your browser. Less common reasons include using an outdated browser or having a corrupted browser cache. Now that you understand the possible scenarios that can cause error 8DDD0020, here are effective methods that can help in solving this error.
1. Update Your Browser or Use Internet Explorer
If this error appears while accessing the Windows Update Catalog through a third-party browser such as Google Chrome or Mozilla Firefox, begin by updating your browser to the latest available version. Often, Microsoft blocks connections from outdated browsers due to unresolved security vulnerabilities, resulting in the 8DDD0020 error. If your browser is up to date yet the problem persists, switch to Internet Explorer, which is installed by default on all Windows versions. To launch Internet Explorer, press Windows key + R to open the Run dialog. Type ‘iexplore’ and press Enter to open Internet Explorer. Once Internet Explorer is open, visit the Microsoft Update Catalog and check if the 8DDD0020 error persists when installing updates.
2. Reset the Internet Options Cache in Internet Explorer
If you experience the 8DDD0020 error while using Internet Explorer (especially IE 8 or older), an ActiveX issue may prevent a secure connection with the Windows Update Catalog. To fix this, perform a comprehensive reset of Internet Explorer from the Internet Options’ Advanced tab, clearing its cache and temporary files.
3. Revert from Internet Explorer 11 (Windows 10 Only)
If this error occurs on Windows 10, a known glitch in Internet Explorer 11 may be causing the problem. Disabling IE11 will force Windows to use the previous browser version, potentially eliminating the error. Note: This change is reversible. After resolving the update issue, you may re-enable IE11 by following these steps in reverse.
4. Perform a Repair Install or Clean Install
If none of the previous solutions have worked, the issue may be rooted in system file corruption preventing your system from connecting to the Windows Update Catalog. To resolve such deep-rooted issues, resetting all related Windows components is necessary. There are two effective approaches:
Repair Install – This advanced method refreshes all system files while retaining your personal data, applications, and settings. While highly effective, it requires compatible Windows installation media.Clean Install – A straightforward process that reinstalls Windows from scratch. This method erases all data on the system drive, so creating a backup beforehand is crucial if you wish to preserve your personal files and applications.
