1. Start > Run > Cleanmgr [ENTER]
follow steps to clean junk files
2. Start > Settings > Control Panel >> Internet Options
a. General tab> Click Settings, make sure it's set to "Every visit to the page" and the Amount of disk space to use" is somewhere between 20 and 50. Lower is not good, and higher is a waste of space.
b. Security tab> Click "Default level" for each zone.
c. Privacy tab> Set to Medium and click Default (if enabled), click on Edit, and make sure hotmail is not blocked there.
3. Rinse and repeat all this every 1-2 weeks depending on how often you browse. That's called preventive maintenance =P
