Win95 was also the first to incorporate Internet capability (a TCP/IP stack) in the operating system, which by 1995 was a very big deal. On Windows 3.1, you had to use third party software (such as Trumpet Winsock) if you wanted to get onto the Internet in a meaningful way (such as running a web browser.)
Not quite. Windows 95 shipped without TCP/IP and it required the Plus-pack (which TBF was included in many OEM-versions) with Internet Explorer 1.0 to get a TCP/IP stack installed (or install third party software, like Netscape Navigator). Also Windows 3.11 for Workgroups got a TCP/IP add-on pack from Microsoft before Windows 95 was released. Microsoft eventually bundled their TCP/IP stack with Windows 95 in Service Pack 1 which also came with Internet Explorer 2.0.
