Can i use my msdn/technet win7 key to reinstall?

If i remember right, keys from msdn/technet got 10 activations or something? So am wondering if i want to reinstall windows 7 with the same key, on the same hardware, will i use up another activation on that?

MSDN/Technet keys are the same as retail keys. Doesn't matter if you use up the activations (however many it may be); if Windows won't activate automatically you just select the phone method and call up Microsoft (usually takes 5 minutes or less).

Ah, so i can install Win 7 on 10 different computers with the same key, and reinstall windows on those however many times i want with the same key?

But lets say i change some hardware, like the motherboard or the OS hdd/sdd? Then it will probably fail? But then i can just use the phone options as mentioned above and explain the situation? Or will it count as a "new" computer and use one more of the 10 activations?

Oh, so you get 10 different keys, and each key can only be used on one computer at a time? But you can use it to reinstall as many times as you like. Did i get it right this time? Or am i still off? Hehe.

Another question, are you sure that a single key can only be used at a single computer at a time? That you can't use the same key on say 2 different computers at the same time?

Don't be getting all greedy now.
