Is there no Safari for Windows 10 ?

There is no version of Safari for Windows 10.

Safari for Windows was discontinued several years ago.

While you can install Safari 5 for Windows on Windows 10 and it will run, it's highly recommended to not do so, since it's not updated and may have many unresolved security issues. Apple no longer offers it for download and any downloads you may find in other websites may be loaded with malware.

Apple stopped developing Safari for Windows.

Please use another browser of your choice.

theres no longer any safari development for any version of any OS other than Mac OS X now, but you have Microsoft Edge which is crappier than Safari used-to-be several years ago.
