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.
The Windows.old folder is huge.
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:
- Press the Windows key + R shortcut to open the Run box. Type cleanmgr here and hit Enter to open the Disk Clean utility.
- Select the drive letter where your Windows 8 is installed (most likely C: drive)
- On the next screen, click the button that says Clean Up System Files.
- 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.
Remove the previous Windows installation in Windows 8
The Windows.8 folder will now be deleted giving you plenty of extra disk space for your programs and documents. See more ways to recover disk space in Windows.
