I grabbed this information from Petri IT. There’s nothing more annoying then having to insert the Windows CD in to a users machine if you need to run an “sfc /scannow”, especially when they’re at a remote site or on another floor. As a solution I recommend doing a few things:
First, install http://www.slysoft.com/en/virtual-clonedrive.html or your favorite ISO mounting software and point it to a network location of the ISO of your windows CD.
Next, Open the registry editor and go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup
and Highlight the Setup folder.
On the right pane, locate the SourcePath. You can either change this SourcePath to the the drive that your ISO software has setup OR if you’re feeling adventurous, to the location of the server that contains these files, or to the local drive that you might have copied them to.
Double-click the SourcePath and replace the drive letter in the box to C:\ (if you copied the files to your C:\ drive). Make sure it’s C:\ and not C:\i386.
Close the registry editor.
If the system ever needs files from the i386 folder, it will automatically look in the C:\i386 folder.
