Hi there! So pretty much every other question I have had since I started building my new rig was answered here by searching old threads. But I'm having difficulty finding an answer to this latest snag. I do hope this is the right place for this.

I've built a new system, and everything is working great. I formatted an old, smaller HDD to use as my new C Drive and installed Windows 7 on it. My previous computer was running Windows XP, and I didn't want to even mess with trying to upgrade it. I do, however, want to keep using the drive as secondary to my C Drive.

Is there any way I can preserve my program settings? I.e. Firefox recognises the scripts, plug-ins, and add-ons I've installed, my IM client automatically pulls up the accounts I was using before the new system, etc? So far when I run the programs from the old drive, they act as if it's the first time they've been run. I'm sure there's a simple regedit I could be doing to make this work, but I just can't seem to find the answer.
