Install WAIK supplement for Windows 7 SP1

WAIK Supplement

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.

Step 1

First you need to download the supplement ISO. waik_supplement_en-us.iso


Step 2

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.

Step 3

Open up a command prompt window, type the following, and hit Enter.

xcopy S:\ “C:\Program Files\Windows AIK\Tools\PETools” /ERDY

Waik SP1 Install 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!

Step 4

Type the following and hit Enter:

xcopy S:\*winpe-dot3svc* “C:\Program Files\Windows AIK\Tools\PETools” /ERY

Waik 2nd Install SP1
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.

  1. I sure would like to see that WAIK supplement available for download again. It still isn’t available and I missed the first round of downloads! Any idea if it ISO was pulled or just not posted properly by someone?

  2. I was getting “access denied” when running xcopy. I didn’t realized I had to run command prompt as admisitrator in step #3. n00b move on my part, but fyi for all the other n00bs out there.

    1. Yes, if you plan on making any changes to a SP1 image you need the supplement. There’s a reason it was made available.

  3. Im having issue booting to a thumbdrive following these new instructions.. or more specifically I think it’s the WAIK Supplement changes. I used your 3.0 tutorial and it worked like a friggin champ for months. Yesterday I clean my DISM/AIK folders and start over from scratch following the new 3.1 instructions and now boot issues. I get a Windows Boot Manager error complaining about not finding \windows\system32\config\system

    Anyone else having this problem?

  4. Your xcopy options are wrong. Instead of xcopy S:\ “C:\Program Files\Windows AIK\Tools\PETools” /ERUY, use /ERDY. It’s an important difference. /U only replaces existing files. /D replaces older with newer.

    Also, the second xcopy command is trying to copy a non-existant file. But it’s unnecessary since using /D will include those files that were left out with /U.

  5. Hmm… The Xcopy command copies EVERYTHING from the DVD, not just the core files needed. 134 files? Try over 1,000…
