any computer gurus here?

You can use your own legit disc as many times as you want if you call them for an activation code for it.
They ask if it's only installed on one system (and of course you say yes) and then they give you an activation code for it.

Yup. I had one "store bought" version of Xtra Putrid that would NOT activate "online." I had to call every single time on their height hunnerd numbaw. They would ask me crap like "are you sure you only have this on one computer?" and I would assure them, "only one" and they always activated it.

On a side note, I have several systems "that you are not supposed to be able to do." "Bill" once claimed that an OEM license "lives and dies" with the computer it came with. While this might be LEGALLY true according to Microshit, the fact is, that I've taken say, a 40 dollar OEM box which I bought at the thrift store, WHICH HAD NOT been used for "some period" and WOULD NOT be reused.......the computer that is..........and taken THAT product key and created an activated, working computer. A completely different machine, different hardware, using the "thrift store" product key.

Another example is an Acer OEM came with Winhozed 7. It died completely----dead motherboard. I used the license to load up another laptop I have up and running.

Another side note...............You seem to be able to LEGALLY download winhozed 7 ISOs make a simple hack, and create a disc that will install ANY version so long as you have the matching product key. This is VERY handy as you don't have to keep track of endless versions of CDs and DVDs

BEAR IN MIND this is not a pirate deal. You cannot use your "Windows 7 starter" or "Windows 7 home" product key to install Winhated 7 Ultimate. You must match your product key to the version you are going to install

If I remember this, when you boot up the Windows installation disc you have created, it goes through all the usual gyrations, then at some point, pops up a menu where you select which version you are going to install.
