I can’t imagine a company with an IT department moving to 10 this early.
The companies are not doing this adoption in one big bang. They are doing it slowly and incrementally.
According to the article:
“The survey found that approximately 23 percent of companies with 500 employees or more have at least one instance of Windows 10 on their networks compared to a mere 5.3 percent of organizations with less than 50 people.”
