How to delete Windows.old folder in Windows 10

This tutorial describes how to delete Windows.old folder from your Windows 10 drive, which usually is the C:\ drive on your HDD drive. The first question should be; Where does Windows.old folder comes from? The answer is simple, when you refresh your Windows 10, upgrade to Windows 10 from an older version of Windows, or custom install the operating system in the same drive where a previous version of Windows was installed without doing a clean install of Windows 10, you will end up having a Windows.old folder in your C drive – C:\Windows.old. Windows.old folder contains all your previous Windows files, which can be quite large in size.

If there already was a C:\Windows.old folder before performing a Windows refresh, upgrade or custom installation without formatting the partition or clean install, then it’ll be renamed to C:\Windows.old.000 other than the C:\Windows.old folder. It means Windows will always rename the most recent previous Windows installation to Windows.old.
