  • You should have 20 GB of empty space for the 64-bit edition of Windows 8.1 and 16GB of empty space for the 32-bit edition of Windows 8.1, on the partition where Windows 8 is installed. This space will be used to download and install the Windows 8.1 update. The download alone will use 3.6-4GB of space.
  • Your Windows 8 installation must be activated. If it isn't, the update won't be available in the Windows Store.
  • You should backup your important files, to make sure you won't lose them. Problems should not occur but you never know how things may start to malfunction. If you don't know what tool to use, don't hesitate to try the built-in File History feature.
