Remove the Previous Windows Installation after Upgrading to New Windows

Published in: Windows

When you upgrade to Windows 8, the program files and folders of the previous Windows installation are moved to the Windows.old folder.

If the Windows 8 upgrade happened smoothly and all your programs are working as expected, it may be a good idea to get rid of the Windows.old permanently as it could be holding tens of Gigabytes of precious disk space.

Windows.old Folder The Windows.old folder is huge.

How to Delete the Windows.old System Folder

Windows.old is a Windows System folder and hence it cannot be removed using the good old Shift+Delete keyboard shortcut. However, Windows does include a utility to help you get rid of this bulky folder forever. Here’s how:

  1. Press the Windows key + R shortcut to open the Run box. Type cleanmgr here and hit Enter to open the Disk Clean utility.
  2. Select the drive letter where your Windows 8 is installed (most likely C: drive)
  3. On the next screen, click the button that says Clean Up System Files.
  4. The utility will rescan your C: drive but this time, it will add a new option that says “Previous Windows installation.” Select that option and click the OK button.
