Validating my windows xp
Upgrading your public facing websites and services that use public certificates (e.g. For those who are running a Windows Certificate Authority (CA) to issue private certificates to servers and devices on your network, there is potentially a different problem: How do you ensure that your private CA is able to issue SHA2 certificates, and if not, how do you upgrade it so that it can?certificates you purchase from a public Certificate Authority, aka “CA”, online) is actually fairly easy; buy a new certificate from a competent supplier, install it, remove old certificate. I’m going to discuss the methods I use, which are designed for a Windows PKI infrastructure with several levels (a root CA and subordinate “issuing” CAs).If you’re not aware of these risks then please look around.
You state that you "upgraded" your computer..your computer is an OEM system, a change of the motherboard would be viewed by Microsoft as a different system and that may account for the stated message.
If that's the case...again, a simple phone call to MS should take care of it.
I hardly think that anyone is interested in pursuing a legitimate customer for installing XP (any version) on a system reflecting changed motherboard, etc.
I called Microsoft and they insisted that it was not a genuine copy and did nothing more than ask me to spend more money.
Last year I reinstalled that very same Windows 7 and they validated it without any problem at all. Yes I did replace the motherboard, also the processor, memory and GPU, and yes I was asked to reactivate Windows.
