I have a feeling that a lot of those who do still use VB6 are using it on an older OS as well. I know I have saw numerous posts where people are using it under XP still. I personally am mostly using it under Windows 7 though I do have it installed on 8 and 10 and have used it on XP and 2000 quite a lot over the years.

I have also noticed that one of the forums I have been a member of for a long time now has saw a huge reduction in VB6 related posts. It used to be pretty active and now it will sometimes be several days between posts even longer if you do not count the ones that are really VB.Net or VBA it seems that about 2 out of 3 new posts there are not actually VB6 or earlier. So either the forum has lost appeal to VBers or they are moving on.
