I am trying to use the Windows repair program and running in safe mode is strongly recommended. When I ask the program to run in safe mode it stays in regular mode. The computer is connected to a wi-fi network. Then as instructed by the program I tried to enter safe mode manually by using F8 during start up and chose Safe Mode with Networking, opened logon screen, entered password but password was not accepted. I'm stumped. Would appreciate any suggestions that can get me going. I'm using Windows 10 Pro that is up to date.
