I have a Dell All-In-One 2320 (originally came with Win7). I upgraded to Win10 and it worked for approx. 11 months. Then black screen only. I took it to MS store and they told me Dell only supports Win10 on certain Dell computers (I couldn't believe it, but, unfortunately I found this to be true). So they uninstalled Win10 and reinstalled Win7, along with most of my data. They said that they couldn't transfer my Norton Security and that I could reinstall (download) at home. To my Surprise, the Norton Security did get reinstalled along with Win7. But MS had installed or activated MSE also. So what do I do? MSE is listed in my Programs. Should I just uninstall it? Will it cause complications because I am running Norton Security while MSE is active? Please advise.
