What is Delivery Optimization?

Delivery Optimization is a built-in Windows feature designed to save bandwidth when downloading updates for your operating system. Instead of each computer independently downloading updates, Delivery Optimization enables the sharing of updates and apps across multiple devices in your local network and on the Internet.

This means that if one PC in the network downloads an update, other PCs in the same network can get the update from it instead of downloading it again from Microsoft servers. Thus, it significantly reduces the overall bandwidth used and speeds up the update installation process.

What is Delivery Optimization

While Delivery Optimization is a helpful feature, it also creates temporary files during the process. These files can take up a considerable amount of storage space on your hard disk over time, especially if you don’t often clear your temporary files.

Can you delete Delivery Optimization files?

Yes, Delivery Optimization files can be safely deleted from your Windows 11 system. These are essentially transient files created during the download and installation of updates. They do not contain any critical system data or personal user information. Hence, deleting them will not impact your computer’s functionality, data integrity, or stability.

However, it’s worth noting that these files serve a functional purpose in the update process. They act as local caches for updates, contributing to speeding up the installation process, particularly for computers within the same network. So, removing these files might mean that subsequent updates may take a little longer to download and install, as they’ll have to be downloaded afresh.
