I only did it on new pc's that had never been in customer's hands, not existing accounts. If computers came in for repair I didn't touch the settings.
Some had Google as their homepage. Some Facebook.
I learned this when they would be like "Josh, the internet is down, can you help me?" and I'm like wahhhhh? Come to find out Facebook had an outage. "I just opened the internet and its not working". :facepalm:
Supposedly the second search box in the results fooled a substantial proportion of those people into entering their search term rather than clicking through to Google.
That is the level of tech illiterate users many people had to deal with back when IE 6 was a current browser.
