IIS depends on HTTP windows driver

[Costas]

Lives @

//http.sys v10.0.19041.1
//1.531kb on Windows 10x64
//
//http.sys v6.1.7601.17514
//736kb on Windows 7x64
C:\Windows\System32\drivers\http.sys

//registry 'service' settings
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP

so the next time you are in troubles, among iisreset, first try restart HTTP driver!!

//once execute this, IIS stopping
net stop http

//start HTTP driver
net start http

//then start IIS
iisreset /start

http.sys on Windows7 doesnt have dependencies.
http.sys on Windows10 depends on MsQuic (more - MsQuic, its implementation of Google-spawned TCP-killer QUIC)

Windows10 http.sys & msquic.sys files, transferred to Windows7 system

querying the service with sc

sc queryex http

struggling to find out whats wrong, in the end the solution is to stop RedGate.Client.Service.exe

moreover (an old thread) :

Services MMC doesn't list http, as it's a driver and not exactly a service.

This command will tell you, how http driver is configured and what happens whey they start. From Admin Command Prompt, type:

sc qc http

Thanks to Win32Guy and Jacques Koekemoer for the wonderful work, interpretation & Technet link. SC : Microsoft Docs

I want to take into account the broader aspects, keep Print Spooler in the center & develop an understanding. I want to mention:

Print Spooler Dependency Tree, i.e., The system components Print Spooler depends upon:

>>Print Spooler (Spooler) depends on Remote Procedure Call (RPCSS) & HTTP Service (HTTP)
>>RPCSS depends on DCOM Server Process Launcher (DcomLaunch) & RPC Endpoint Mapper (RpcEptMapper)
>>HTTP doesn't have any dependencies.
>>Dcomlaunch & RpcEptMapper doesn't have any dependencies.

So now we have found the proper tree & roots. We have to start with the roots!
HTTP is a service & a driver, but all the others are services & are located in/by services.msc. You can't find HTTP there.
A question arises, how to work with/on HTTP? sc commands are good to work with HTTP as well as services mentioned in services.msc.
