Services that can be disabled on SQL servers

Hi All, 

I have two servers (with 1 SQL instance each) and 1 SSRS server.

I think, the below services are not needed on any SQL servers and would like to DISABLE them:

HTTP SSL - DISABLE
IIS Admin Service - DISABLE
Print Spooler - DISABLE
WinHTTP Web Proxy Auto-Discovery Service - DISABLE
World Wide Web Publishing Service - DISABLE

Out of these, I would like to keep 'IIS Admin Service' and 'World Wide Web Publishing Service' ENABLED on my SSRS server so as to keep the SSRS reports portal working.

Can I have your views?

Any help is highly appreciated.

Thanks,

Mandar
