Try looking at this Dell support video. It may make the instructions easier to follow.
My Inspiron 5567 with 1TB hard drive and 8GB RAM is running incredibly slow and I wish to restore to factory settings! I have tried to follow the instructions on the Dell Forum  .....   to begin the process to create a Dell Recovery and Restore USB drive, download the Dell Recovery Restore software from the Dell link:Recovery And Restore Have installed Dell Recovery & Restore on my other (good) PC and have attempted to transfer the software to my 30GB USB Drive, as follows.. Open Dell Recovery & Restore to transfer the software to your USB drive This was closed following installation of the software! On your desktop, click the Dell Key Creator icon to open the application. Have done this but nothing happens! Connect a 16 GB or larger USB drive to any available USB port. On the Dell Recovery & Restore application window, (this was closed following the installation of Recovery & Restore so unable to select a USB Drive) select the USB drive as the media that you would like to use. The software should detect the USB drive. If it is not detected, click the Refresh icon next to the drop-down box. If I try to run R & R from the zipped file (I cannot find an Icon) then I am given the option to Repair or Remove Direct Key!
