7-Zip usage recommendation
Microsoft recommends to use 7-zip
Today i got around, and watch This Week C9: Win7 on MSDN, PDC 2009, Drunktender, in this episode there was a reference for how to deploy Windows 7 to a VHD without installing it by Scott Hanselman. When I was reading the article i found that the author recommended usage of 7-zip to extract the Windows 7 Iso, with a little side note.
If you're not using 7-Zip, you're missing out on life, BTW
