Microsoft Windows Vista PID Checker is a tool to get detailed information on the PID, ID1, ID2, Type, Subtype, Class and Crypto ID from any Windows Vista Product Key. For example, if you found a Windows Vista product key but unsure whether it’s a Ultimate, Business, Home Premium or Home Basic key, simply enter the product key in the Microsoft PIDX check tool, click on the Check button and within seconds it’ll reveal detailed information about the key.



I’m not sure this tool is developed by who because it has no credits, name, links or whatsoever. I searched in Google and also Microsoft website about this tool but with not much result. The only reason I can trust this tool is because it’s from a reliable warez site. The only info I got from warez site about this tool is it is intended for those who have some knowledge and understanding of the mechanism of activation Windows Vista.

It is possible that this tool is created to harm innocent people by infecting it with trojan or virus and distributing to the internet for people to download. I remembered once I found a free ICQ tool that is able to do check user invisibility and after using it, my ICQ UIN has been hacked. So now I am very cautious on these type of tools. I’ve ran a thorough check on this tool for virus/trojan and it’s CLEAN.

I can’t provide the download link to this tool because I think it is violating Microsoft policies. Logically, Microsoft wouldn’t create such tool for every people in the world to use other than “maybe” their activation center.
