How to free storage space after Windows 10 Upgrade or Feature Update

Before we go ahead and start cleaning the Windows 10 after upgrade or update, make sure you have all the files as before the upgrade. If no, then you need to look into WINDOWS.OLD folder in the C drive. It carries all the data before installation.

If all files are in place, then the easy way is to delete the Windows.OLD folder and you can claim back most of the storage space. However, there is a better way to do it. Windows has an in-built feature which helps you claim back storage space.

Disk Cleanup Utility for Drives

  • Open File Explorer from Task Bar, and select This PC. It will list all your drives.
  • Right-click on the drive you have the backup stored. If you were never asked to select a different drive, then you need to choose the C drive.
  • Right-click on the drive > Properties > Disk Cleanup. You should see the wizard looking for files thats taking up space.
  • It will list files that can be cleaned, look for a button which says “Clean Up System Files.” Click on it.

Uninstall Previous Windows Installation

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

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

2] Storage Sense in Windows 10

  • Go to Settings > System > Storage
  • Select the Primary Drive, and then click on Temporary Files

Windows Update Cleanup usually takes a lot of space post update or upgrade. It keeps copies of all installed updates from Windows update, even after installing the newer version of updates. Windows Update cleanup deletes older version of updates that are no longer needed.

Once the scan is complete, select the one you want to delete, and click on the Remove files button.

  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.
