Norton Security is my preferred application to protect my computers for years, so I never expected that I run into a problems with my new Windows 10 clean installation. But let’s start from the begging. Two days ago I have to do clean Windows 10 installation. I done this as many times before, no problems here. And after that I installed Norton Security from Symantec site. Also this part went smoothly. But after I restarted my PC error screen appeared “Diagnosing your PC“. And then another screen error that problem can’t be fixed. And again and again in a loop. What’s the hell???

I tried few solutions and nothing was working for me. For example I have fully updated Norton Security before Windows has been restarted. Nothing.

How to fix the problem with Norton Security and Windows 10?

Well problem solution looks simple now but It was real challenge to me to find out. Before you install Symantec application you have to update your Windows 10 to at last build 10240! If you are not sure which build do you have right now you can check it in very easy way. It’s simple. Just press Start button on your keyboard with “R”. Then enter “winver” and press enter. You will get current build of your system. And when you update your PC you can install Symantec application and then restart your computers. Everything works now.
