OS: Windows 10 Home 64-bit - Unable to remove Windows.old folder.
The first time I upgraded from 8.1 to 10, the Windows.old folder removed successfully with Disk Cleanup. After a clean (post-upgrade) installation, the folder cannot be deleted with either Disk Cleanup or CCleaner.
Right-click delete, message:
