[H] tech net renewal

[Winterlight]

After three years I think I am going to let my MS Technet 
subscription lapse this year, maybe pick it up again next year. If 
nothing else I am curious to see if they come back at me with a 
better offer.. like a magazine subscription.

What happens when you do this... anybody know... will it effect my 
installed keys or keys I have that haven't been installed yet?
thanks
