Windows.old is automatically generated whenever you perform an installation of Windows with a previous version of the OS already installed. It creates this Windows.old folder in the root of the Windows partition and stores the previous operating system files and data.
This is part of the safety mechanism in case the upgrade process goes wrong. If the installation fails for any reason, the system can use the Windows.old folder to undo the changes. Also, if the upgrade completes successfully, the backup copy of the previous version will be kept to provide the option to rollback in the case the new installation is causing issues.
Although this is a handy feature, if your computer is working correctly after the upgrade, you can safely delete the Windows.old folder to reclaim gigabytes of space.
we'll walk you through the different ways that you can get rid of the Windows.old folder to free up several gigabytes of space to store more important files.
