    So, my 2009 MBP froze a lot on Windows 8 for no apparent reason and I couldn't find any solution on these forums so I'm sharing this with you:

    If your MBP freezes with Windows 8, open the command prompt as administrator and type:

    bcdedit /set disabledynamictick yes
    Then, restart.

    That fixed it for me. I think the issue is limited to MBPs with Core 2 Duo processors, by the way.

    This is very interesting. My PC (also a Core2) actually had freezing issues in the RC build. I might try this.

    Thank-you inket!

    I noticed that I don't have a freezing issue but my keyboard doesn't work, internal or external. I can't use windows 8 because of that.

    Thanks for the info, I hope this works.

    I had no problems until recently. I installed a new SSD into the mac mini and reinstalled Mac OS 10.8 with boot camp Win 8 and Win 8 has been freezing constantly.
    This is the first actual fix I've found but i think/hope it will work :)
