I have WXP-64 running on a VM and, for testing and performance reasons, I would like to occasionally change the allocations for it. Changes might include:

• Number of CPU cores,
• Amount of RAM
• Add/remove network adapters.

But I'm concerned that XP will demand re-activation and that I might eventually have licensing issues if I do this.

So, can anyone tell me:

1. What kind of changes trigger re-activation in XP?
2. Is there limits or caveat with regard to re-activation?

I've perused this question and the article it references, but wanted more recent and verified info.

(FWIW, I'm not trying to cheat: the OS copy was purchased explicitly for the VM.)
