Get rid of the old stuff=More Space on Chuwi Hi8
When you upgrade to Windows 10 over an existing Windows 7 or 8 installation, it keeps a copy of your old operating system around in a folder dubbed Windows.old just case you need to revert back for any reason. If you know you’re never going back you can delete that folder to reclaim the lost gigabytes—but it’s not as simple as right-clicking on it and selecting Delete.
Search for “Free up disk space by deleting unnecessary files”. Click the shortcut, select your primary hard drive (if you have multiple installed), and in the window that appears, click “Clean up system files.” After Windows thinks for a second, check the “Previous Windows installations” box in the list, then click OK and confirm you want to delete the files.
