I have a group of Netbooks at home that came with Windows 8 and updated to Windows 8.1
When the Free Upgrade to Windows 10 came out I updated all but one of the Netbooks to Windows 10 by doing the download to a memory stick so that I could do them offline.
The deadline for the Free Upgrade has now passed and I have two questions.
1) One of the Netbooks is becoming quite slow. This is used by one of my kids and there is probably a lot of c##p downloaded onto it. I have him working on getting rid of all the stuff he doesn't need but I suspect I will end up doing a factory reset. Will the Factory Reset reinstate W10 on this device or will it reset to W8 and I have to go through the upgrade process again? Will the downloaded copy of W10 installation still be valid?
2) The Netbook which is still running W8.1; will the downloaded copy of the W10 installation work on this device?
If the downloaded copy of W10 installation won't work, where is the best value for getting a licensed copy of W10 for these devices? I guess as I have 4 devices that were originally W8, it would be worth buying something that can be installed on multiple machines. My current desktop came with W10 so I guess any reset (hopefully won't be required for some time if at all) will restore W10 to that machine. I am also in the process of rebuilding an older desktop which had Vista on it so could potentially need 5 licenses.
