How to remove windows.old

Delete your previous version of Windows



Ten days after you upgrade to Windows 10, your previous version of

Windows will be automatically deleted from your PC. However, if you

need to free up disk space, and you're confident that your files and

settings are where you want them to be in Windows 10, you can safely

delete it yourself. Keep in mind that you'll be deleting your

Windows.old folder, which contains files that give you the option to

go back to your previous version of Windows. Deleting your previous

version of Windows can't be undone.
