@wdormann is it possible to apply that no-foistware win10 tweak without creating a non-Microsoft admin account on the box? Use case is just that- not wanting to create a local admin that isn't my Live account. Or is there no way around it since you need to be offline?
Any time you're logged in (as anybody) and also connected to the internet, you're at risk of getting the foistware. I've only tested with local accounts, but if you don't delay in making the registry change and rebooting you can probably beat the flood.
