I have a Z400 from the second hand, and lately they have been calling me HP distributors, telling me they are willing to sell another one. Since I have not registered any purchase, I assume that my computer has personally sent my private data to HP, and based on that, the company has identified personal information, address and company name.
Maybe someone know how to turn this 'funcionality' off (probably in the BIOS, because the system is clean, I installed it myself, without the HP application) is spying?
