I ran across this where a Service Manager installation on just a few systems would hang constantly and the computer at that point would be unusable. Once you closed the Service Manager console the system would be back to normal. Through troubleshooting found that it was the WPF Font Cache that was causing the problem. Worth a shot if you have consoles that are constantly hanging or crashing on certain systems. In services.msc its called Windows Presentation Foundation Font Cache 126.96.36.199 or the actual service name is FontCache188.8.131.52.
Stop the service and navigate to C:\Windows\ServiceProfiles\LocalService\AppData\Local and delete the FontCache184.108.40.206.dat file. Once complete start the service back up and launch your console. If it was the FontCache causing your problem then your console should run great.
