The reviews have been so good for Microsoft's latest operating system that some consumers decided to exchange what they already had in hopes of getting an upgrade.
Experts at Symantec, the anti-virus software company, have had the program for quite some time.
"I have to say that versus my laptop, which is running Windows XP, versus my Windows 7 machine at home, I prefer my Windows 7.1 for all sorts of reasons," said David Cole, director of Symantec's Norton Group.
