These are instructions for installing the new The Windows Automated Installation Kit (AIK) for Windows 7 SP1. This is assuming that you have WAIK RTM already installed.
First you need to download the supplement ISO. waik_supplement_en-us.iso
Now you need to mount the WAIK supplement .iso. (I highly recommend Pismo Mount for mounting). Right click on it and assuming you have Pismo mount installed, select “Mount.” For map drive do letter S: (I am using the letter S for this example, you could use a different one), for Access do Read and Write, and then click mount.
Open up a command prompt window, type the following, and hit Enter.
xcopy S: “C:Program FilesWindows AIKToolsPETools” /ERDY
If it worked successfully it will have copied 134 File(s).
You Should No Longer Need the Step Below because of change above in command from ERUY to ERDY which now replaces old files. Thank you Wynn Smith for the tip!
Type the following and hit Enter:
xcopy S:*winpe-dot3svc* “C:Program FilesWindows AIKToolsPETools” /ERY
If it worked successfully it will have copied 82 File(s).
You have now fully updated your WAIK RTM client with the new PETools, including WinPE 3.1. You should now read our tutorial on Syprepping a Windows 7 Machine from start to finish.
