Additionally, Windows will automatically delete the cached files that are older than the number of days set in the second policy. From now on, Windows will only use the amount of space allotted by you to cache Windows update files.

Restart your system to apply the changes. For instance, if you would like to keep the cached files for a week, you should enter 604800 in the value field. Under the Options section, enter the amount of time you’d like to keep the cached files in seconds and hit the “Apply” and “OK” buttons. Just like before, select the “Enabled” radio option. Next, find and open the “Max Cache Age (in seconds)” policy.ĥ. If you’ve chosen to set the cache size by percentage, calculate the percentage you’d like set aside in your C drive and enter that value.Ĥ. Under the Options section enter the amount of space you would like to allocate and click on the “Apply” button. In the policy properties window select the “Enabled” radio option. If you’d rather set the cache size in relative terms, such as a percentage of your C drive, find and double-click on the “Max Cache Size (percentage)” policy.ģ. This policy lets you set the cache size in gigabytes. On the right panel, find and double-click on the “Absolute Max Cache Size (in GB)” policy. Go to “Computer Configuration -> Administrative Templates -> Windows Components -> Delivery Optimization.”Ģ. Open Group Policy Editor by searching for “gpedit.msc” in the Start menu. Change Delivery Optimization Cache Size and Cache Age via Group Policy Editorġ.

If you think Delivery Optimization is using a lot of space or not retaining the cache long enough, you can change that behavior using Group Policy Editor or Windows Registry Editor. Moreover, as new updates arrive, Windows will update the cache accordingly. Of course, if your drive has low disk space or Windows deems it necessary, it will automatically clear the cache and free up space.
