Is it possible to transfer windows 7 installed on one computer to a new "virgin" computer?

Yes it is possible, note that you will be transferring everything, and that includes drivers not made for your machine that you will have to uninstall afterwards, to do so you can use software such as "clonezilla" that makes a full disk copy, clonezilla can be run from a USB or from a CD. There are many other ooptions available to do this but it is the only fully free one I know of.

*****EDIT***

Following your question about directly plugging the HDD to a new computer: Yes you may, without any issue, I wouild however be extremely surprised that you are using an IDE HDD that uses the master/slave concept, even in the end those HDD's had jumpers to be set automatic, and since a (very) long time we have been using SATA HDD's that dont use the master/slave principle. If you chose to move the HDD, you are not transferring the license at all, even tho it's a new PC windows will recognise it as a hardware change/upgrade and say nothing of it (you would see tons of drivers get installed at 1st boot and thats all)

Two things...

1.- it is possible

2.- may not work properly

The main thing is the motherboard and it's drivers... You can try, use a program like Norton Ghost or similar to create an image of your actual "C" drive, then with the same program you can remount it on the new computer...

I forgot to ask... Will you change your ENTIRE computer? I ask this because you can try to put your ACTUAL disk drive in the new computer and see how it works... I'm an IT and tried this many times...some times it worked, some times did not...

let me know how it goes or any other "sub" question about it...

If you have the license key for Win7 from your current rig you can use it to install Win7 of the same version on the new rig after deactivating the previous install. If you don't have the key you can obtain it using software such as SIW (System Information for Windows).

Why do you want to go 10 years back. Windows 7 is the best right now. I`m a Windows user since 1994. also Windows xp is 95% targeted from crackers.

Hey,

Here I got Diner Dash 2: Restaurant Rescue for free: http://j.mp/1BDxx4Y

it's a perfectly working link, no scam !

The objective of the game consists of saving your friends from some evil builders that want to tear down their restaurants in order to construct a gigantic shopping mall

It's amazing.

There might be a way to do it but:

The license key is tied to the motherboard so moving your drive or drive contents to a new machine invalidates the license.

The legal way to do it is to do the telephone activation thing explaining why you need to move to a new machine.
