Hotmail is a free email service offered by Microsoft. The service can be linked with several social networking sites, as of early 2011, and may be accessed from a computer or smart cell phone. If you need to know when you created your account for any reason, the information is stored by Microsoft and may be accessed within seconds after you log in.
Log in to your Hotmail account and click the "Inbox" option.
Click the "Options" icon in the upper right-hand corner of the screen. Select "More Options" from the drop-down menu.
Find the "Managing Your Account" section and choose "Account Details."
Locate the "Registered Since" line in the "Account Information" section of the page, which lists the exact date you registered your Hotmail account.
