How to optimize Delivery Optimization cache in Windows 10

Delivery Optimization (Delivery Optimization) feature in Windows 10 allows you to upload and download Windows 10 and Microsoft Store updates as well as from other computers on the local network or on the Internet.Windows does this by using self-organizing distributed localized caches.By default, Delivery Optimization cache will use up to 10GB of your C drive space and be retained for three days.

Of course, if your drive has low capacity or Windows feels necessary, it will automatically clear the cache and free up space.Moreover, when a new update is sent, Windows will also adjust the cache to best suit it.

If you think that Delivery Optimization is using a lot of space or not keeping the cache long enough, you can change specific settings using the Group Policy Editor group editor or Windows Registry Editor.Here's how to proceed.

Change the size and time of Delivery Optimization cache storage via Group Policy Editor

2. In the Delivery Optimization window, look to the right panel, find and double-click Absolute Max Cache Size policy (in GB) . This policy allows you to set the cache size in gigabytes. If you want to set the cache size according to relative amounts, such as the percentage of C drive, find and double-click the policy called Max Cache Size (percentage).

6. Finally, restart your system to apply the changes.From now on, Windows will only use the amount of storage space you allocate to store Windows update files.In addition, Windows will automatically delete cached files older than the number of days set in the second policy.

If you want to revert the settings, select Disabled or Not Configured for both policies and then restart your system.
