Windows 7: Copying a HDD & Running It On 2 Machines?

Copying a HDD & Running It On 2 Machines?

I know you guys do not condone hacking but I have a question.

My OS is Win7 Pro x64. My PC is a home build.

I had an OS RAID1 WD640GB HDD fail and WD replaced it with a WD1TB Blue. So I cloned the remaining 640GB to a RAID1 set of WD 750GB RE3 drives and all is well.

Now I have this 640GB with Win7 Pro x64. I have another System very similar in hardware being the mother boards are both Gigabyte. The one above a GA-EP45_UD3P and the other one a GA-EP45 DS3R.

If I were to put the 640GB in that one would MS detect it as a second instance and make it fail?

Yes, you cannot run Win7 on more than one machine at a time. It will be deactivated on a second machine if cloned with activation intact.

The solution in your case is to SysPrep your HD on the old hardware which will remove all drivers, activation and hardware ID's so it will start up on the new hardware. You can then insert a Product Key purchased for this purpose.

Forget it. That will not fly. Run Linux on the other system. It is free.

Would you mind a suggestion in that direction?
Maybe you could try Linux Mint: Download - Linux Mint

The latest release, Julia, is the one I'm currently running (along with Windows 7 and XP for legacy software) and I feel very comfortable with it.
The DVD edition comes with quite everything available out of the box (codecs, an office suite, flash, and so on) and it even looks good:

Well, I guess it's all about taste anyway...

And yes, as whs mentioned, you don't have to pay for it

F12 different on two machines
Below are examples of what I see when pressing F12 with IE11 on different machines. Both have the same set of updates. The first is on a Sandy Bridge with a i5-2550K, second an i7-3770K. Both are running w7 Ult 64bit. EDIT: First image is from IE10, my mistake. Why the difference? :confused:
