How to Free Up Space After Upgrading to Windows 10

When you upgrade to Windows 10 from Windows 7 or Windows 8.1, the upgrade assistant will always backup your existing installtion either in the same drive ( C Drive) or to an external drive / partition if you choose to. This is important so when you want to rollback, you have all your files and data.

Windows Need Space for Backing up Existing Installation

Now after a while when you are all set with Windows 10, the space occupied by the backup is not much of use. While you can always go and manually delete them, Windows 10 has better way to clean it up. As a matter of fact, this was feature was there in previous version of Windows, but if this is new, this will help.

  • Open File Explorer from Task Bar, and select This PC. This will list all your drives.
  • Now right click on the drive you have the backup stored. If you were never asked to select a different drive, then you need to select C drive else choose the drive you had used to save the backup.
  • Now right click on the drive > Properties > Disk Cleanup. You should see the wizard looking for files thats taking up space.
  • Once you get the Disk clean up wizard back, with list of files that can be cleaned. Look for a button which says “Clean Up System Files”. Click on it.

Uninstall Previous Windows Installation

  • This will rerun the wizard, and this time it will search for Previous Installation.
  • When the Wizard comes back, scroll down the list to find it. Check and clean it up.

Clean Up old Windows Installtion

That said, make sure you are perfectly ok with the new OS, and don’t want to return back to previous installation, before cleaning up the backup files.

  1. sir i recently refresh my windows 8.1 laptop by using the option “Refresh your PC” after doing that my system came back to windows 8 version.When i upgrade to 8.1 and update the version KB3035583 and KB2976978 the windows 10 upgrade offer option is not shown in the task bar.
    So how it will come back in my system

  2. 1. Nice tip! By the way, I am planning to reset Windows 10. I dont mind if the 3rd party apps are uninstalled as I have their setup files. But will I loose the drivers as well?
    2. Also, sometimes the OS starts hanging. Like when I click start icon, the start menu comes up after 1 minutes or so. Are you facing similar issues or this is the problem specific to my PC?

    • 1. You will have the drivers which supports Windows 10. If you not, you will be warned in advance.

      2. Nothing on my Dell which is 6 yrs old as of now.

      • I have sorted the lag problem. Online protection of quick heal antivirus was slowing the system and increased the boot up time. Now it’s working properly. The only problem is that the recent Windows 10 update is not getting installed.
