Despite the marketing push, Microsoft developers do not try to hide the fact that Windows 7 is an extension of efforts made for Windows Vista.
Windows 7 fixed or improved many of the things people didn't like about Windows Vista, but Raimund Genes, CTO of security firm Trend Micro, has found something that he much preferred in the earlier OS.
Genes said that Microsoft made design decisions this time around that sacrificed security in the interest of usability, mostly because of Microsoft dialing back User Account Control (UAC).
"I'm not saying Windows 7 is insecure, but out of the box Vista is better," Genes told The Register.
"I was disappointed when I first used a Windows 7 machine that there was no warning that I had no anti-virus, unlike Vista," Genes said. "There are no file extension hidden warnings either. Even when you do install anti-virus, warnings that it has not been updated are almost invisible."
