This is a discussion on cpu usage within the Motherboards, Bios|UEFI & CPU forums, part of the Tech Support Forum category. when i'm running windows live messenger ,it causes a 100% cpu usage,so how can i solve this problem ,
hi, the problem is probably with memory leackage. You cab either reinstall the live messenger, or you can go to windows update and get the latest update.
Of download a newer version of this software, probably a corrupt file or it might be infected.
If it crashes just end the task until you update software.
