Another option is to use an SD card as well but be careful because SD cards drivers are not migrated if the device doesn’t support Connected Standby.

You don’t have to use an external hard drive or USB for installation. But if you don’t use it, you’ll see that on your hard drive there’s a previous version of Windows available.

Don’t worry, this version will be automatically deleted after 30 days, or you can delete it manually right now if you want.

If you decide to use a USB stick or external hard drive during Windows 10 installation, your previous version of Windows will be moved to that external device.

As you can see you don’t need that much space in order to install Windows 10, but if you want to save maximum space, you might want to use external storage to store your previous version of Windows.

Alright, so now that you have all the information you need to upgrade your low disk space device to Windows 10, let’s quickly sum up the steps to follow.

  • My Windows 8.1 Tablet has only 4GB to GB free on the SSD. None of the many suggestions I have read for freeing up space apply because I have used them all, plus several others, over the past months. I am encouraged by the references to making use of a USB Flash Drive and my SD Memory Card so I would welcome more information and advice on this.
