how to find the display name for IIS v10 or above in regkey value

Question

Hi All,

I am trying to get the Inventory list for IIS applications using below string on SNOW tools.

IIS v8 we are using thus key to discover the product --> HKLM/Software/Microsoft/Windows/current version/Uninstall String/&BF61.....8CCC7 --> Display name "IIS version 8"

Same we are trying to fetch the regkey path/value to discovery purposes. But we are not seeing the regkey value "Display name "IIS version 10"

Looking your valuable commands.

Thanks,

Nagarajan.

Answer 1

IIS is a Windows component, not something that can be uninstalled via Add & Remove Programs. As such checking the registry isn't the correct way to do this. There is no uninstall option for IIS.

If you have PS then the preferred approach is to use Get-WindowsFeature. This tells you whether a feature is installed. Unfortunately, I think it only works on Server OS.

The registry keys for IIS can change between versions so using the registry is iffy at best. However, at least on current Windows 10, you can look for HKLM\Software\Microsoft\InetStp\VersionString. If IIS is installed then it'll contain a value there. But that can change in newer versions of IIS so be warned.

The only supported registry keys for IIS are documented in articles like

https://learn.microsoft.com/troubleshoot/developer/webapps/iis/general/use-registry-keys

So, if you use PowerShell to query

Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\InetStp"

you will find what you need, either a certain patterned string, or raw version numbers.
