After installing Update Rollup 1 for Windows 2000 SP4 on a computer that is using a hyper-threading processor, or a dual-core processor, the CPU temperature increases abnormally.

To resolve this behavior:

1. Open a CMD.EXE window.

2. Using REG.EXE, installed from the Windows 2000 Support Tools, type the following command and press Enter:

<b>REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\HAL" /V 14140000FFFFFFFF /T REG_DWORD /F /D 16</b> NOTE: Restart Windows 2000 for this change to become effective.
