    Hi,

    Is there a way to enable dual CPU's in Home Premium? as I'm fed up with having to fork out for the Pro/Ultimate editions with the extra junk that's not needed. :rolleyes:

    Not exactly dual-CPU, but if your CPU and your mobo support hyper-threading, it will automatically divide your one CPU and trick your PC into thinking you have 2, so then it will divide up the tasks.

    My CPU's are duel Zeon's with Hyperthreading and Premium just see's one CPU with hyperthreading but not the other unfortunatly, I've seen somewhere that it's possible to copy over the HAL drivers from PRO to Premium would that maybe work?

    You can try this as Administrator:
    1.- Open CMD as Admin
    2.- Type "bcdedit /set numproc 2"
    3.- Restart the system

    With this you may be able to see your two procesors, also I would recommed you to turn off hyperthreading, since that's only a emulation to see 2 cores, otherwise you may wanna try the "numproc 4", If something goes wrong you may need to use the recovery console from windows.

    Unfortunately you may be SOL as the saying goes... Home Premium is locked to 'a single physical processor'... And Ultimate is not...

    IIRC, Home Premium supports only 1 physical CPU, but unlimited Cores in that single physical cpu (unlimited = max 4 for quad core cpu's, or 8 if quad core with HT)

    I'm afraid you are right, it was the same with XP's Home and Vista's Home premium supporting only one proc typical M$hit. I just object to paying double for an OS just because I choose Multi CPU as opposed to Multi Core solution. I would stick with XP pro but it didn't play nicely with my system, Vista Ultimate was better by not crashing every five mins or so, but other than that it was a right royal pain in the butt trying to get anything done. Windows 7 is better by far.:rolleyes:
