Let me tell you a little story. Last year, my appartment was broken into and my computers stolen. Of two Windows copies, the insurance company agreed to reimburse only one. Apparently they have problem with paying for software...

Since I keep all my CD keys seperately, I ended up calling MS to get a new key because the old one refused to install on the new computer.

Guess what, they refused to cancel the old one and give me a new one because the license is tied to the stolen hard drive. Great.
