Most. Tedious. Upgrade. Ever.
Let's hope they can make the installation happen either faster, or at least not need so much disc space.
Tried upgrading an Asus netbook with only a 32G SSD, but otherwise adequate performance, with the previous Creators Update. Wait for Windows Update to download and then run the installer - sorry, needs 8Gb space on C: (there was about 4G available), with no way to use space on another drive.
Download the media creation tool and the appropriate update image, prepare a USB stick, plug this in and run the setup program. No, still needs 8Gb spare space, but at least with the option of using another drive. Plug in a second USB stick and tell it to use that. So the upgrade process starts.
Four days later... the progress has reached 9%. With the disc and USB drive lights flashing away, so obviously not hung.
Another day later... reboots back to the original installation, "Sorry, the upgrade failed".
Try again. Uninstall antivirus, Chrome, Office 365... now enough space. Run the USB upgrader again, which thankfully only takes overnight and succeeds. Then reinstall everything.
Now looking forward to having to do the same in a few months' time...
