I downloaded the Vista with SP2 from the following link. http://www.mydigitallife.net/2009/0...streamedintegrated-dvd-iso-image-bt-download/ I verified the Hash values of the ISO after downloading it and the Total bytes, SHA1 and CRC values are same as it posted on MSDN and Technet site. So, I installed this downlaoded Vista with sp2. However, upon reboot it gives an error, the Windows defender doesn't start but everything else looks normal. When I try to start the Defender manually through services, the error says, "Windows could not start the Windows Defender service on local computer. Error 0x80096010: The digital signature of the object did not verify" The error 0X80096010 is the genuine advantage checking error. It sounds fishy. This ISO was released by Russian site and wonder they have hacked it somehow and made the hash values same as the MSDN release. Anybody has installed from this download?
