How to Change Account Picture in Windows 10 can be handled safely by first identifying the exact feature or application involved, then using its supported controls.
Steps
- Open Settings > Accounts > Your info.
- Choose the available option to browse for/take a new account picture, depending on the Windows build and account type.
- Select a square or easily cropped image and save the change.
- If a Microsoft account supplies the picture, allow time for account synchronization or manage the profile image through the Microsoft account where appropriate.
- Lock/sign out and check the sign-in screen if the old image remains cached.
What to know
A local Windows account picture and a Microsoft account profile image can be related differently depending on how the PC is signed in. Changing one does not always update every Microsoft service immediately.
Important cautions
Use an image you are comfortable displaying on the lock/sign-in screen. Windows 10 is beyond normal support, so interface paths may no longer match current Windows 11 guidance.
Verify the result
Lock/sign out and check the sign-in screen if the old image remains cached. Afterward, confirm the change with a normal test before removing an original file, old configuration, recovery option, or working account that could be needed to undo the change.
Additional guidance
Older account pictures can remain in caches or account history even after the current image changes. Do not delete unfamiliar profile files from system folders merely to remove an old thumbnail. If the picture is controlled by an organization account, policy or directory synchronization may determine what is shown.
