How to delete Delivery Optimization Files and reclaim lost disk space on Windows 10 PC

Can I delete Delivery Optimization Files? If you have this question, read on, as this post will show you how to delete Windows Update Delivery Optimization Files & reclaim lost disk space on Windows 10 PC.

Windows 10 introduces the Windows Update Delivery Optimization feature, wherein your computer may get updates from or send updates to neighboring computers or computers on your network. Although this would mean that you get updates much faster, it would also mane that you are left with bigger bandwidth bills, as well as lost disk space in saving these Windows Update Delivery Optimization Files.

We have already seen how to turn off Windows Update Delivery Optimization. Now let us see how to delete or remove the residual Delivery Optimization Files if any from your computer and reclaim disk space.

Delete Delivery Optimization Files

Run the built-in Disk Cleanup Tool. Type Disk Cleanup in the search box. Then click on the result to open it.

When you run this tool, if any Delivery Optimization Files are found on your computer, they will be displayed in the results.

Select the check box against Delivery Optimization Files to delete them.  These Delivery Optimization Files are files that were previously downloaded to your computer. They can be deleted if currently they are unused by the Delivery Optimization service.

Since you have already disabled Windows Delivery Optimization feature, you can safely delete these files.

The files could be just a couple of MB’s or even mush larger in size, and thus deleting them can help you further reclaim disk space.

I have noticed one thing on my Windows 10 computer. Even when I have disabled  Windows Update Delivery Optimization, every once in a while, I see it turned on back! Maybe it happens after some Windows Updates. So you need to check this setting on and off and check that that the setting has not reverted from Off to On. You may consequently also need to delete the Delivery Optimization Files regularly.
