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"
