operating system

just downloaded speccy. it seems to work fine on all topics but "operating system". It never completes the analysis. I have not let it run for hours, but at least 15 minutes. still doing something. Is this long time normal and should I let it run longer or is there a problem.

I did do a search on topics and could not find an answer. thank you.

What is your operating system?

Is it 'non standard' in any way?

Which drive is the operating system installed on?
