as far I understood windows is creating 2.0 and 2.1 type zip files but I dont 100% know when its using 2.1 type
That's different from your previous posts in which you stated that a specific version was created by default in Windows. If you don't know in which cases which version is used then you don't know which is the default.
You might have a reasonable request but you have not presented the information in a straightforward way so it's time for me to "dust my broom". Good luck.
[EDIT] Triple ninja-ed! No better time to bow out.
