I just received my MSDN subscription and I have a few questions about the keys that I am able to receive from MSDN. 1) How many RTL (Retail) keys can I generate per account? 2) How many simultaneous activations is each RTL (Retail) key good for? 3) How many simultaneous activations is each MAK (Multiple Activation Key) key good for? My understanding is: My understanding is that you get 10 RTL (Retail) keys per product. Each RTL key is good for unlimited activations, but only 1 at a time (only one computer activated at a time) Each MAK key is good for 500 simultaneous activations (500 computers activated off the same key at the same time) I was wondering if anyone could clear this up please as the MS help is not very helpful.
