Processor upgraded yet system still rejects changes
Switched from a Pentium D to a Core 2 Quad in an Optiplex 760. The new processor is working fine in Ubuntu but still shows "Pentium D" in Windows. It runs much faster and makes use of the C2Q, though it doesn’t display this feature. You might want to try extending the CPU change time—pulling the battery for a bit longer could help.
Ensure it restarts and checks for the issue. Also, you can delete the previous CPU entry in Device Manager by right-clicking it and selecting uninstall device.
Also remove the PSU from the wall, activate the power button, and keep it on for a few minutes to release the capacitors in the BIOS. Simply taking out the battery won’t do that.
It was essentially two NetBurst P4 chips combined. Your Pentium model is a dual-core processor from the Core 2 line.
