Stopping and removing IIS

Stopping IIS

If you temporarily don't use IIS, you can 'turn it off'.
Optionally, stop all web sites, ftp sites and application pools:

ls iis:\sites | stop-website -ErrorAction SilentlyContinue
ls iis:\sites | % {$_.ftpserver.stop()}
ls IIS:\AppPools | Stop-WebAppPool

Stop all related services. Please note that WMSVC and ftpsvc may not be installed on your machine.

Stop-Service WMSVC 
Stop-Service AppHostSvc
Stop-Service W3SVC
Stop-Service ftpsvc
Stop-Service WAS

Disable the services

Set-Service -Name AppHostSvc -StartupType disabled
Set-Service -Name w3svc -StartupType disabled
Set-Service -Name ftpsvc -StartupType disabled
Set-Service -Name WAS -StartupType disabled
Set-Service -Name WMSVC -StartupType disabled

You should see that nobody is listening to any web ports anymore:

netstat -an

To Enable IIS again:

Set-Service -Name AppHostSvc -StartupType Automatic
Set-Service -Name w3svc -StartupType Automatic
Set-Service -Name ftpsvc -StartupType Automatic
Set-Service -Name WAS -StartupType Automatic
Set-Service -Name WMSVC -StartupType Automatic

Start-Service WAS
Start-Service W3SVC
Start-Service ftpsvc
Start-Service AppHostSvc
Start-Service WMSVC

ls iis:\sites | start-website -ErrorAction SilentlyContinue
ls iis:\sites | % {$_.ftpserver.start()}

Removing IIS

Close IIS Manager if you have it running.
Uninstall any IIS Extensions, it's better to do that before uninstalling IIS.

$app = get-WmiObject -Class Win32_Product -namespace "root\cimv2" | Where-object{$_.Name -match "IIS URL Rewrite Module 2"}
$app.Uninstall()

We can remove most IIS components with the following command:

Uninstall-WindowsFeature -Name Web-Server -restart
Uninstall-WindowsFeature -Name Was

or on older Windows versions:

dism.exe -online -Disable-Feature -FeatureName:IIS-WebServer
dism.exe -online -Disable-Feature -FeatureName:WAS-WindowsActivationService

There are still some files in "C:\Windows\System32\inetsrv","C:\inetpub" and your content directories. Leave "inetsrv" alone, but you can delete the others.
