Amazon as usual fantastic. But the product was no good. Would not charge within two weeks of purchase. Returned to supplier bit still waiting for refund. HP know of the fault but supplier still selling them. Amazon please beware.
For the money it is excellent. We bought 175 of these for students to use. They all come with Windows 8.1 Education and are entitled to the free Windows 10 upgrade. However, we advised the students not to upgrade because there isn't enough disk space for the device to download the Windows 10 upgrade files, unpack and install - it runs out of disk space.
However, I also bought one for my daughter for Christmas and I can confirm that Windows 10 installs on it perfectly. If you go to Microsoft's website and download the Windows 10 upgrade files to a USB stick (3GB min space), put it in the laptop and click the setup.exe file, all the hard work will be done on the USB pen, not taking any space on the laptop. Once the upgrade has finished, you go to the properties of C drive and click Disk Cleanup, Advanced, Remove Previous Versions of Windows and it will delete off the old Windows 8 files leaving you with a Windows 10 laptop with some 16GB free space (assuming you had nothing else on it).
