Recently I have been pressed relentlessly to register to MS emailing. I never heard of this before & always logged in with my own email address &password. As at times I could not continue I accepted for their em address not knowing what I was letting myself in to.
The thing infiltrated everywhere from logging into start the PC to my account in IE & other instances.
Is there a way to revert to the original ways.
