In Windows 8, you can modify your account picture by clicking on your username in the upper-right hand corner of the Start screen and then choosing "Change account picture" from the drop down menu. From the Personalize window that appears, you can either choose an image file by clicking the Browse button, or you can take a picture with your webcam by selecting the Camera option. ACCOUNTPICTURE-MS files are saved in a proprietary format and cannot be viewed with a standard image viewer. They are located in the following directory: C:\Users\[user]\AppData\Roaming\Microsoft\Windows\AccountPictures\ NOTE: During the Windows 8 beta, Microsoft used the .USERTILE-MS extension for account pictures. These files were referred to as "user tiles." However, Microsoft adopted the term "account picture" for the final release version of Windows 8.
