Today I went to the Windows Live Hotmail site and logged in. The first thing it asked me to do was change my password. I changed it, because it was the only way I could log in. I'm not sure why it asked me to do that. I didn't request a password change. This wasn't one of those fishing emails that takes you to a fake link asking you to change your login. I opened my browser and typed in the address manually, and after logging in it asked me to change. Seems very strange. I logged into my Xbox Live account, and there wasn't any activity on it in my account history. I've never had a hotmail password expire before, and I log in regularly. Should I be worried?
