Follow these steps on your own risk, playing with registry is not good - that's what Microsoft always says

  1. Download and install Interop Tools

Goto Xda developer forum and download and install a suitable verson of Interop tools. This app will unlock your phone registry setting and will expose the system folders when connected to USB

  1. Unlock the file system

Open the application click the hamburger menu --> unlock --> Interop unlock there will be a button for Full Filesystem Access just enable it

  1. Delete the files in folder

After you connect your phone with USB you will be presented with two root folder Phone and sd card (if you have one). Go to the folder Phone\Data\ProgramData\SOFTWAREDISTRIBUTION\Download select all and delete as individual deleting will cause problems

Small Note:

At times you will not be able to delete files from the Phone directory saying "Cannot delete xxx: It is being used by another person or program." to resolve this download and install Unlocker you can find it in as well in Github or from
