How to Delete the Windows.old Folder in Windows 7

Information

If you performed repair install, upgrade install, or a custom install without formatting the drive for a clean install and selected to install Windows 7 on the same partition of the previous Windows installation, then you may have a C:\Windows.old folder left over in your new installation.

If you already had a C:\Windows.old folder in the installation that you performed a repair install, upgrade install, or a custom install on, then it would be renamed to say C:\Windows.old.000 (older previous installation) in addition to the C:\Windows.old folder. The most recent previous installation will always be in the C:\Windows.old folder.

This will show you how to delete the Windows.old folder(s) generated during the installation to free up the hard drive space that the Windows.old folder(s) takes.

   Note

The C:\Windows.old folder contains folders and files from the previous Windows installation. Be sure to copy any files or data that you may still want to keep to another location before deleting this folder.
