Windows.old on your C: drive - Remove to free up space
Usually, but not always, after installing Windows 7 you will have a Windows.old folder on your C: drive that contains your files and data from the previous Windows installation, and can be used to revert back to a previous version of Windows. Open Windows Explorer and under "Computer" click on the C: drive - if the Windows.old folder is on your hard drive it will contain all your files from the previous Windows system, and it can be deleted if you don't need it to free up space on your hard drive.
If it's not there, make sure you can see the Windows.old folder:
- Click Start, type: hidden
- Click "Show hidden files and folders"
- Click to select "Show hidden files and folders"
- Click OK and look for the folder
(Note: after you are done go back and uncheck "Show hidden files and folders" if you want.)
You must reinstall programs if you did a custom install, they won't run from the Windows.old folder.
You can cut/copy and paste your personal files from the Windows.old folder to your Documents folder, or use this method:
