The Windows Automated Installation Kit (AIK or WAIK) is a free tool for building custom Windows 7 images and deploying them in a specific environment. But the tool does come with a few limitations that IT administrators should be aware of. For example, they could find that its impossible to put together an unattend.xml file from within the Microsoft Deployment Toolkit (MDT) 2010 for a custom Windows 7 x32 image. The reason is related to the limitations of WAIK. Specifically, “if you run Windows 7 x32 and WAIK x32 you can create unattends for both x64 and x32 custom images. If you run Windows 7 x64 and WAIK x64 you can not create unattends for x32 custom images. Running x32 WAIK on Windows 7 x64 is not supported,” revealed.
