This copy of windows is not genuine>

Lenovo MT-M 6075-BQU (from 2007) Windows Vista 32 bit Business. I have just run Easy Recovery Essentials to fix a boot issue "OS not found" using a USB, seemed to go well, but after removing the USB and trying to exit the program hung on the white screen Easy BRE logo, after quite awhile and in the absence of any buttons I shut it off using the power button. After allowing it to finish a very long boot and a restart (to let it fully shut down and start up) I got a black desktop and a message lower right corner saying Windows Vista TM Build 6002 This copy of Windows is not genuine. The fact is it is genuine, there seems no way to talk to Microsoft and virtual assts. get non of it. Is there a way out of this?
