When you upgrade your PC to Windows 10 without first formatting the hard drive, the install wizard will keep a copy of the previous version inside of the Windows.old folder in case you want to go back to your previous version of the operating system. However, that folder definitely takes up hard drive space on your computer. So if you have been satisfied with Windows 10, it’s a good idea to remove the Windows.old folder from your PC. And in this tutorial, we will be presenting to you how to remove it. Take a look.
The Windows.old folder is located in the hard drive, typically the C: drive. But note that you can’t just press Delete on your keyboard to delete it completely, you will need to use the Disk Cleanup tool to do this task. Just follow the following steps:
Step 1: Open File Explorer with the keyboard shortcut Windows key + E.
Step 2: Choose This PC from the left pane.
Step 3: Below the Devices and drives section, right-click on the drive containing the Windows 10 installation, and then choose Properties.
Step 4: Click on the Disk Cleanup button, and then the Cleanup system button.
Step 5: From here, tick the box for Previous Windows Installation(s) to delete the Windows.old folder. Plus, you can tick the box for Windows upgrade log files or Temporary Windows installation files to delete those files that can also waste your valuable storage space on your computer.
Step 6: Click on OK.
Step 7: There is a dialog requiring you to confirm the deletion. Just click on Delete Files.
Step 8: On the Disk Cleanup warning, click on Yes to complete the process.
That’s it. You are all done removing the Windows.old folder from Windows 10. Note that once the folder is removed, you cannot go back to the previous version unless you perform a clean installation of the current operating system.
