If what you really want to do is "migrate" your current Windows 7 setup to a new PC, and retain all the stuff you have now, you can do that using Macrium Reflect Pro version -- which does cost some money.
The Pro version comes with something known as Redeploy. You use it as follows:
1) Make an image of your current Windows 7 setup to an external drive
2) Use an app to save off your current Windows 7 drivers
-- I use DoulbeDrive to do this. This is important because you are likely to need some of these drivers on the new PC.
3) Make the WinPE Boot CD from the Macrium app -- you will need this on the new PC
4) Hook up the external drive (containing the image backup) to the new PC
5) Boot the new PC from the WinPE Boot CD
6) Use the option to Restore the new PC using the backup you made from the old PC
7) Reboot again from the Boot CD
8) Choose the MR option to restore to different hardware -- have a disk with the new drivers for the new PC read
9) MR will replace the old drivers already in Windows with the new drivers from the disk for the new PC
When you reboot from the hard drive, you will have all the old drivers replaced with the right new drivers.
Also, any hardware that does not work, that was carried over from the old PC, can have the drivers installed from the backup you already made.
