I happened upon this idea when I ran a backup on my one laptop that has the Windows7. Another backup feature is the mirror image and I thought..Why not? My morals aren't really concerned with 'bootlegging' Windows7 from my one laptop to use on my other. I was just concerned if it could be done successfully or if in the process would I mess up that laptop.. Before I came up with this idea I originally planned on buying the software anyhow so I'll just stick to that.. Thanks again, CDWright + 0 Votes This is a license issue dldorrance Updated - 3 years ago Windows which comes bundled with a computer will only work on that computer. This is by de$ign. Now if you purchase a retail version of Windows, you may use it on multiple computers, but only one at a time. As an example, I own 3 retail versions of Windows XP, which over the years have resided on at least a dozen different motherboards. One workaround might be to look into a brand of Linux (free) on one of your machines. You can try one out without altering your existing OS by downloading Ubuntu or Mint linux, for example, burning a CD and booting the CD. Linux will be loaded into memory only (not on your HDD) and you can try it out. It is not written to your HDD unless you specifically choose to install it, at which time it will ask you if you want to install it side-by-side with the existing Windows, or to replace the existing Windows, effectively destroying the Windows.
