Create a New User Profile
Windows user profiles are simply folders stored on the hard drive that contain all of the files and settings associated with a user account. If you have more than one name to click on when you first turn on your computer, then it means Windows has a profile for each one of those names. Occasionally, user profiles can become so bloated that files can be corrupted and this can result in user profiles that are either slow to load or may even cause program errors.
To make a new user profile in Windows 7, open the Control Panel and click on User Accounts. This will show your current account and allow you to change the name, password, picture, and so on. If you click Manage another account, it will show you all of the user profiles on the machine. To make a new one, just click on Create a new account and enter the information.
Once you have created the new user profile, reboot your computer then log in with it instead of your old one. If you see a noticeable improvement in load time, then you can go into your hard drive under the Users folder and copy the documents and photos from your old profile to the new one. Just to be safe, don’t delete your old profile because you may need to go back to it from time to time.
