This morning I turned on my PC and I tried to use the windows 10 search box but it no longer works! It will not accept my typing any text into it and the windows 10 icon in the task bar is not working either. When I try to bring up Microsoft Edge all I get is a quick flash and then it disappears! I can click on anything else and it works fine. Cannot access start menu to go to advanced settings for a rollback to Windows 7. I am sick of this Windows 10 nonsense. Is there a simple way to roll back to Windows 7 ?
