Not good; I literally spent 2 months cleaning up my Dell so that I could do some Win32 development with Code::Blocks, and use the Rf9 flight simulator. From "Cortana" to MacAfee Microsoft has really screwed up Win10 big time; which leads me to my main point... you're not having a problem with Code::Blocks, you're having a problem with Win10.
Use Task Manager and Procexp to find out what is honking up your system. You'll find some bloatware or rough service that is not playing well in the sandbox... especially considering that this didn't start until after Win10 updates. NEVER put on optional updates or fixes for anything you are not experiencing directly... turn most of the updating off and manually select it when you notice that everyone is running fine.
When you say "freezing" please be more specific. Is it the debugger, the editor, the perspectives (project management stuff) or is the entire app "not responding"; or is the desktop frozen?
Sorry you're having trouble.
