Since HP can’t seem to make the SP3 patch for XP work with its AMD procs, Microsoft has blocked these computers from getting the free update from Windows Update.
The bug affected AMD-based computers that were getting updates for Intel-based computers on accident, notable those made by HD. This would cause endless rebooting as the machines couldn’t utilize the downloaded software.
No word from MS on when updates for the AMD-based computers will be out, but we’re hoping shortly.
