Windows still runs on 71% of the desktop and laptops [1]. In my experience a good number of applications start life on simple desktops and then graduate to servers if they are successful. I work in the field of analytics. I have a locked down Windows desktop and I have been able to try out all the other databases such as MySQL, MariaDB, PostgreSQL and DuckDB because they have windows installers or portable apps. I haven't been able to try out ClickHouse. This is my experience and YMMV.

surely you have Docker though?
Fair point, but if your desktop is locked down then you might not be able to use administrator privileges that many programs require for installation (especially software that uses DRM and licenses). So you might be not able to run the software even if there was a Windows version.
