At one point yesterday I restarted the computer and Windows Defender Security Center had a red x. I had it check for problems and it said my temporary Internet files had changed location. Made no sense to me. I told it to fix it and was taken to a page where I could reset Microsoft defaults. So, I did that.
Well, apparently it reset other defaults as well, as today I discovered my default Browser and pdf program had been changed. I hope I don't find anything else that matters!!
So now, when I went to my WordPerfect forum and then here, I had to log in again. I can't imagine why my computer defaults would affect that, but it's the only reason I can think of that both sites suddenly didn't know me.
