Windows 7 was better received by the market because it was BETTER than Vista. Windows 8 was crap and got he reception it deserved. Merely releasing 9 without removing the crapstatic TIFKAM interface will result in poor reputation.
The reasons Internet Explorer got a bad reputation:
1. It was tied to the operating system, unnecessarily. The browser has exactly zilch to do with the operating system. ActiveX controls, tying versions of the browser with versions of the OS, varying behaviour of same browser version on different OS versions etc. If IE is renamed, it should be delinked from the OS like other browsers.
2. Intentional non-compatibility with standards, because of the arrogant assumption that with marketshare they can bully the World.
3. No sandboxing, no protection from ads, popups, malware downloads, sucking upto to the MAFIAA in proprietary standards and DRM.
Fix these issues in the browser FIRST, then call it Internet Shit-hole, but people will still buy it.
