Various applications and settings can interfere with the connection to Microsoft’s update servers. The internet connection itself may also be the cause of the 0x80240fff error. The following possible scenarios are the most common:
- Your internet connection is heavily strained by streaming services or large downloads by other devices in your local network.
- In areas with poor internet service, available bandwidth can be lower during the evening hours, when multiple neighbors are using streaming or other services.
- Wi-Fi connections tend to be much more unreliable than Ethernet connections, so you’re more likely to have problems when installing an update over a Wi-Fi network.
In many cases, it helps to simply wait and repeat the update at a later time. If you’ve ruled out your internet connection as the source of the problem, you can optimize your software and settings:
- Turn off third-party antivirus software and firewalls.
- Close third-party VPN software. This software may interfere with updates even if you’re not connected to a VPN.
- Also close all other active programs if you receive the 0x80240fff error message.
- In the Windows settings app, go to “Update & Security” > “Delivery Optimization” and disable the “Allow downloads from other PCs” option.
