Windows Update Delivery Optimization Cross Network Corruption

I have three machines running 15063.11 builds and last night I noticed that my main computer and XPS 8700 had two odd files within the Program(x86) folder. One file was a Lenovo program the other was an AMD VulkanRt program.

The Dell XPS 8700 machine had no reason to have an AMD folder because it uses an NVidia graphics card. Likewise the Dell product has no reason to have a Lenovo program folder.

Why is this happening? All three machines after updates to 15063 appear to have been automatically set by Windows to use Delivery Optimization for updates within settings. Thus within the local network one computer can share downloads that may have already been downloaded by another computer on the network. Besides the XPS 8700, I have a Lenovo Yoga 710 laptop and an XPS 8100 with an AMD graphics card. It appears the Lenovo has been attempting to download a driver/firmware update and XPS 8100 has been attempting to download an AMD update that somehow began to show within the XPS 8700 Program(x86) folder.

It appears to me, there may be some issue of corruption within the present update system.

Anyone else seeing this issue?

I have been an Insider since the beginning of the program an never seen this apparent corruption. Actually, I have always had the machines set to not allow download optimization.

I installed all three 15063 builds recently using the new ISO from Microsoft. It appears the ISO automatically changed my setting of OFF for update delivery optimization to ON.

Done.
