My experience with relatives' computers has been that trying to completely remove Chrome from Windows is a lot like trying to remove a rootkit, specifically one that phones home a lot.
If any other company did those sorts of things in persisting pieces of their software all over the OS without easy removal for non-technical users, people would be calling it malware or spyware.
