Here is how you can remove account picture history in Windows 10. To avoid this, you should erase account picture history on your system. So in case if you’ve synced once, and later you change your account picture but if some services are not synced, the older picture will continue to display.
However, when you use Microsoft account, your account picture will be used across various Microsoft services, as it is synced. Note that local account picture is only displayed on your system. These older account pictures constitute account picture history in Windows 10. You can observe this in below shown screenshot. If you’re using Windows 10 for a long time and if you love to regularly change user account pictures, you might have noticed older account pictures being displayed on Settings app > Accounts > Your accounts. User account pictures can be associated with both local and Microsoft account in Windows 10.
