Issue with "Edit with Paint 3D" Functionality

This is a known issue that usually comes down to the app's file association breaking after a Windows update. The most reliable fix I've found is to re-register the app via PowerShell rather than reinstalling from the Store.

Open PowerShell as Administrator and run:

Get-AppxPackage *Microsoft.MSPaint* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

This re-registers the app without uninstalling it, which preserves your settings and usually restores the right-click "Edit with Paint 3D" context menu entry properly.

If that doesn't work, the second most common cause is a corrupted registry entry for the file association. In that case go to Settings → Apps → Default Apps → search for Paint 3D and manually reassign the image formats (JPG, PNG, BMP) to it.

Also worth checking: if you recently updated to Windows 11 24H2, Microsoft made changes to how UWP apps handle file associations which can break this functionality. Running Windows Update and then re-registering via PowerShell as above usually resolves it.
