msnmsgr.exe has begun freezing and causing high CPU usage and in just the last 30 minutes for four out of ten workstations in our network. When we exit the program (completely closing it) we see CPU usage and memory usage return to normal. In each case, it is Windows 7 64bit workstations, one desktop and three laptops. Each updated with the Update for Windows 7 for x64-based Systems (KB2732059). Not long afterwards this phenomenon began. We have closed the program for now until we find a reason/solution. Any ideas, explanations, or recommendations would be greatly appreciated.

UPDATE: One computer is Windows Vista and did not run udpates this morning. The other six computers in our network continue NOT to have a problem. We have been using Windows Live Messenger since it became available and have not had this issue until today.

    Hello,
    In my office, we are having a similar issue with some of our PCs.
    Windows Live Messenger and Windows XP 32-bit.

    As soon as you log into WLM, memory usage escalates, and CPU usage is around 50% or higher.

    The system becomes unusable until you kill msnmsgr.exe.

    Any advice would be greatly appreciated
    Thanks
    Seth
