    PC won't boot to desktop


    So what I did was that I went into MSconfig and on the boot section I set the maximum RAM at 4000+ and the CPU cores to 2 ,I thought this would boost performance but it just bricked the PC. I tried going into safe mode but that didn't work either, so far my only option seems to be the command prompt but I don't know how to use it.

    Do you have a "Repair" disk or the Windows installation disk to use for a recovery? System Recovery Options - Boot to in Windows 8

    From the command Prompt, type bcdedit
    Look for the Windows Boot Loader entry that contains an item named truncatememory
    Note the identifier for that entry, it may be {default} or {current},
    or a long GUID like {19a662d6-d972-11e3-847f-9663c71f16cb}
    Type this command:
    bcdedit /deletevalue identifier truncatememory
    replacing identifier with the correct one you noted for that entry.

    FYI, Those 2 fields should be left blank and only used for diagnostic purpose. Windows OS determines & uses the max cores and Memory as default.

    Fixed, thanks for the advice.

    PS: I messed with the settings because my PC was only using 1 out of 4 GBs of RAM.

I love Metro, but I think booting into it is worse for me than if the Start menu were hanging open everytime you booted 7. I have to say this is an additional step that makes it feel a bit forced, a bit in the user's face. Has anyone figured out how to go straight to the dekstop?
