Win7 ultimate - how many time can i activate key?

Guyz,

I am planning to buy Win7 ultimate soon, and i have 4 Hard drives on my same Single PC.

So, will i be able to install Win7 on all my 4 HD's and activate without a problem ? OR i can activate only 1 HD with 1 key?

Confused

(anybody using more than 1 Hd on same computer plz respond)

Can you tell us why you would want to do that?

It is unusual, but you will be able to activate the same key on the same machine.

It is no different from installing x86 - then changing your mind - installing x64 , then changing your mind - you can do that as often as you like. Having them in dual boot is no different -you can't boot into more than one at a time - you can only ever have one of them up and running.

I suppose people dual boot x86 and x64 for a variety of reasons - not sure why 4 are wanted.

Hello zinbart,

According to the licensing, you can only have one copy activated at one time. I don't know how long you can re-activate without Windows giving you trouble, but a quick call to Microsoft will do the trick.

So, you could activate all of your copies, but as soon as you do, all others become de-activated.

Hope this helps,

Actually, not true. Microsoft doesn't "deactivate" keys. They simply maintain a count of the number of activations and require a phone call if the limit is reached or exceeded.

The robocall is required if installing to different hardware only. The numbers traded actually deactivate the installation on previous hardware and activate on new one.

Same machine is not detected as a change in hardware, so there is no robocall required no matter how many times.

Okay, I have a related question. If I bought win7 ultimate x64 and activated it on my current rig, a year later I bought a new pc and wanted to activate the same copy on it, would that be possible or am I gonna have to get a new copy?
