    Windows 8 CPU Usage 98-100%


    Hey guys,
    I recently installed the Windows 8 Release Preview, it worked great on my computer for the first two days and now the CPU is maxing out after it's on for a couple of hours. Restarting the OS temporarily fixes it but it's a huge problem for me. Here's a screencap of the services that are taking up all of the CPU:

    I just restarted my computer and now Task Manager says:

    CPU: 4%
    Memory: 29%
    Disk: 14%
    Network: 2%

    I'm going to let it idle without starting any other programs to see if it goes up again.

    Ah, I was unaware that there was a different version. I pre-ordered Windows 8 because I built a new PC, so I'll just wait to install the release version.
    What do you mean 'switch to app' ? Is the screenshot above not enough information?

    I can see Chrome using the highest portion of your memory, just wondering if there may be some under that i dont see. You can sort them out by clicking mem up top

    You could also stop some programs from "Startup" tab in task manager, disable google update and any unnecessary add-ons.
