On the root of your primary drive, create a new folder and name it “Windows8Files”.
Either insert the DVD into your PC or mount the ISO file.
From the viewed wp-content/uploads navigate to D:\sources.
The Windows8Files folder that was created earlier, copy it to the install.wim file of your DVD.
Next you will have to drag your mouse towards the bottom left corner of the screen.
Right click there and select the Command Prompt (admin) from the popup menu.
Next you will have to run reagentc.exe /setosimage /path C:\Windows8Files /target C:\Windows /Index 1 command.
This will allow you to refresh as well as reset your PC without inserting the DVD.
