Replacing the CPU

[Michael A. Covington]

Does Windows object, or even notice, if I change to a different version of
Pentium 4 while keeping the motherboard and all the peripherals the same? I
want to change to one that allows hyperthreading and perhaps has a faster
clock speed.

Putting this another way: Does Windows notice the CPU ID or the low-level
version information in the CPU?

Yes.

Processor type and processor serial number are 2 of the 10 items that
are included in the control value calculation for product activation.

Changing the CPU would change these values but the change would not be
enough to require reactivation *unless* there has been other hardware
changes since the last time Windows was activate. The hardware change
monitoring is cumulative and this additional change may be enough to
push the accumulated total changes "over the top".

Good luck

But the worst that happens is that I call Microsoft for another activation.
Right?

Or is this like replacing the motherboard, where a whole new installation is
required?

That is correct.

Motherboard replacements require a Repair Installation a.k.a. inplace
upgrade rather than a *new* installation.

The Repair Installation preserves the user data files, installed
applications, and configuration settings. Windows Updates do need to
be reinstalled.

Good luck

But a CPU replacement, even when going to a higher clock speed and adding
hyperthreading, does not require even that. Right?

A hyperthreading change MAY require a repair installation.
