Here in this article, we’ll be sharing the possible solutions to Fix Windows Update Error 0x80240023. So, if you’re continuously getting failed to update your Windows OS build or installing it, this troubleshooting guide will help you out. This particular issue can appear whenever Windows users trying to update and install new security or feature update. Windows system basically shows you this error whenever searching for updates or installation gets failed.

Meanwhile, some of the reports are coming out that Microsoft Office 2007 users may get issues with the licensing and encounter the error 0x80240023 as it’s no longer officially supported. Additionally, this error is also quite related to the KB2505184 (Office File Validation Add-in).

• From the Windows Update temporary cache folder, select and delete all files.
• Once done, repeat the same above steps to stop the Windows Update service.
• Next, Right-click on the Windows Update option and click on Start.
• Finally, restart your computer to check whether the error has been fixed or not.

2. Troubleshoot Windows Updates

• Once you’ve got the product key for activation, click on ‘Change product key’ > Enter the key and validate it.
• Finally, run the Windows Updater again and check if the problem still persists or not.
