Now that the Service Pak 1 for Windows 7 is available for download, you might want slipstream it into the Windows 7 installation DVD. The slipstreamed DVD comes in handy as you won’t need to install the Service Pack every time after Windows installation.
We all know that the feature-rich Internet Explorer 9 (IE9) browser is not included in Windows 7 Service Pack 1. So, every time you reinstall your Windows 7, you will have to manually install IE9. To avoid this problem, you can easily slipstream IE9 into Windows 7 installation DVD or ISO.
While it’s possible to slipstream Internet Explorer (IE9) without using a third-party tool, you will need to download Windows Automated Installation Kit (WAIK).
As the download size of WAIK for Windows 7 SP1 is almost 1300 MB, we are going to use a free tool called RT Seven Lite to slipstream Internet Explorer 9 (IE9) into Windows 7 ISO. Moreover, the procedure is very simple in this method.
