If you have user profiles on your computer that you no longer need, you free up disk space by deleting these unused profiles. The steps in this tech-recipe allow you to do this.
1. Right-click My Computer, and select Properties to bring up the System Properties panel.
2. Click the Advanced tab, and then, in the User Profiles area, click the Settings button.
3. From the User Profile dialog box, select the individual profile you want to delete.
4. Click the Delete button, and confirm the action.
5. Click OK.
Please note that User profiles can contain files that you may need. It is good practice to review the directory and backup any needed files before deleting the profile.
