Surprise, it's 2022, and XP is still a de-facto standard Windows version, with hacked Win7 slowly gaining.
Why? Tons of Software was written for XP, and then abandoned without any support. Many of that stuff in the government sector. A lot of online banking clients outright say "only works on XP," and copyright years reads 2006.
This is similar how Android 7+ support was almost nuked in China for nearly a year because Tencent didn't want to port Wechat to newer APIs cuz "nobody uses Android newer than 4.X in China"
That was not why they refused to port it to newer APIs though. It was because Google changed the permissions API to be more granular and request permissions at runtime, which would have meant Tencent would have to request tons of permissions to gather user data (presumably users would not be inclined to grant so many permissions).
