Jules recently posted about her web stats. They tell her, among many other things, that she still has one or more readers who are still on Windows 3.1 (originally released on March 18, 1992). I thought I’d check the stats for this site for the same very, very late adopter. No such luck–the oldest visitors that my Google Analytics account shows are on Windows 95 (two of them in the last month, as it happens).
Then I thought to check what percentage of Windows users are using Vista, and what fraction is still on Windows XP. Windows Vista was released a little over two years ago, on January 30, 2007. It has, as I’m sure you’re well aware, been plagued by criticism. I know many XP users who will skip Vista entirely, moving straight to Windows 7 (as of yet, it has no slicker name).
I checked this site, as well as a client’s site (they’re in the software industry). I compared Windows XP and Vista usage for January, 2008 and January, 2009. Here’s what I found:
For this site, as a percentage of all visitors on Windows:
For a client site, as a percentage of all visitors on Windows:
Those numbers don’t add up to 100% because there’s a fraction of users on Windows 2000, NT, CE, 98, 95, ME and so forth.
I checked a couple of other sites, and the numbers look more like my client’s site than my own. Vista usage floats around the 25% mark for January, 2009. What should the adoption rate look like? I really have no idea. Microsoft surely hoped that a majority of their users would be on Windows Vista by the time they released Windows 7.
