Over 90% of desktops had Windows back then. So yea, that's everybody. Unless you're being pedantic because one guy was using IRIX on an SGI workstation, or the odd Mac.

10% of everyone is still a whole lot of people. Even 1% of everyone is a lot of people.

Of course "everyone" isn't meant literally in a context like this.

No one said “everyone” until you did, and now you’re using it to be pedantic… bad faith tactic that.

Don’t be a troll.
