Today I tried the same thing on the Dell venue 8 pro. It had Windows 8.1 on it. Downloaded/installed all the updates before starting the upgrade. Selected the upgrade icon and downloaded and upgraded to WIndows 10, If its a Dell Venue 8 Pro that has 32gb of space. Windows will not be able to upgrade. It will ask for an external device that has 10GB of free space. So when it asked for that. I used a 16GB USB stick using a USB OTG cable. The Tablet had full charge at the time of starting to upgrade. I could have used a MicroSDcard, but didnt have one on the tablet during test upgrade.

This is usefull when you :
need to be able to control when you can update things.
If people are using software (ex..Toolwiz Time Freeze) that enables a System Restore. It doesnt make sense to let the OS or apps auto update.

"To change this option, open the Settings app, select Network & Internet, scroll down, and select “Advanced options” below the list of Wi-Fi networks. Enable the “Set as metered connection” option. This option only affects the Wi-Fi network you’re currently connected to, but Windows will remember this setting for each individual Wi-Fi network."
So, if you don’t want Windows 10 automatically downloading updates on your home network connection, just set it as a metered connection. Windows 10 will automatically download updates when you connect your device to an unmetered network, or when you set the network it’s connected to as unmetered again. And yes, Windows will remember this setting for each individual network, so you can disconnect from that network and reconnect all you like.
Do you have an Internet connection with limited data? Just mark it as metered and Windows 10 won’t automatically download updates on it. If your connection offers unlimited downloads at a specific time — for example, during the middle of the night — you could mark the connection as unmetered occasionally at these times to download updates and mark it as metered after the updates are downloaded.
