If you choose to install Windows 10 on the same drive where an existing installation is already present, the setup program will create a folder named Windows.old in the root of the drive. This folder will contain a full backup of a previous installation of Windows 8 or Windows 7, including the boot manager and installed apps. This is very handy if you plan to uninstall the currently installed Windows version and return to the previously installed release. It can also be useful if you forgot to transfer some files or settings to the new installation. However, if you are already finished with the migration, then Windows.old just wastes your disk space for no reason. Windows 10 got the ability to delete the Windows.old folder automatically in a recent build. Here is how to enable this feature.

Here is how you should delete it and why it is better to use the built-in OS tools instead of simply deleting the folder from Explorer.
