| 478184 | 2006-08-13 07:29:00 | My sister has a dual core laptop but somehow only one core is running while the other one is dormant. Is it because windows XP doesn't support dual core yet? Do you need to enable dual core? |

| 478187 | 2006-08-13 11:51:00 | Home is ok with 1 physical CPU with multiple cores. www.microsoft.com "Q. How does this licensing policy affect products such as Microsoft Windows XP Professional? A. Microsoft Windows XP Professional and Microsoft Windows XP Home are not affected by this policy as they are licensed per installation and not per processor. Windows XP Professional can support up to two processors regardless of the number of cores on the processor. Microsoft Windows XP Home supports one processor." |

| 478188 | 2006-08-13 23:10:00 | you should really install both the dual core driver and the windows XP dual core hotfix. although if it was a pre-installed laptop it may have those installed already, in taskmanager, when you right click on a process does it give you the option to change affinity? If so then all he extra dual core stuff is installed and there is nothing to worry about |

| 478189 | 2006-08-14 00:04:00 | I'm guessing here but if its an Intel Core Duo (don't know about the AMD Turion X2), it may turn 'off' the second core while on battery, or depending on the power scheme. That is what is probably hapenning. When the computer isn't doing much, it will keep the speed down, and probably shut off a core. When doing more intensive stuff, the speed will be ramped up and both cores should be working (depending on the nature of the programme - ie if its multi-threaded vs single threaded). |

| 478190 | 2006-08-14 02:46:00 | you should really install both the dual core driver and the windows XP dual core hotfix. These, the MS and AMD ones etc are for fixing issues with some games. If you aren't having any then don't bother. The AMD one especially if installed can make other apps etc perform worse. You have to remember there isn't anythng yet that takes advantage of dual core, games at least, yet. So it probably is idle mostly. |

| 478191 | 2006-08-14 08:02:00 | I'm running a Duo core laptop currently. Using DVD Shrink it smokes along. Vs my desktop P4 2.24 it takes 1/4 -1/3 of the time to do the same task on the laptop. | EX-WESTY (221) | ||
