I imagine people have realized there have been no improvements in windows 10/11 but in reality I think it has to do with changes to Windows 10's activation checks. Windows 7 would also be almost impossible to post- patch with AI / LLM garbage which actually makes me want to pull out my old VLK discs..

It is probably just a rise in the number of automated scrapers/bots that use a windows 7-like user agent.
