Problems Removing IIS role

Question

Hello to everyone!!

I have a Windows Server 2016 machine hosted on Azure.

I'm trying to remove IIS role from this server. I get a message that the uninstall process has completed successfully, but when I reboot the machine I get a message saying ‘We couldn't complete features. Undoing changes’. I have run the ‘sfc’ and ‘DISM’ commands and it shows that there are no errors in the system.

Thank you in advance.

Hi Soporte_OP,

in your case, here are some steps you can try:

1. Check the Windows Update history to see if any updates related to IIS were installed recently. If so, try uninstalling those updates and then attempt to remove the IIS role again.
2. Try removing the IIS role using PowerShell instead of the Server Manager GUI. Open PowerShell as an administrator and run the following command: Uninstall-WindowsFeature -Name Web-Server -Restart

This will uninstall the IIS role and automatically restart the server.

3. If the above steps don't work, you can try manually removing the IIS role by deleting the following folders:

C:\Windows\System32\inetsrv

C:\inetpub

However, please note that this is not a recommended method and may cause issues with other applications that rely on IIS.

Hope it helps.

Best regards,

Lei

Hi did you ever resolve this?

I am running into the same issue but on Server 2019.

Uninstalled using Server Manager and uninstalled using Powershell both failed to remove the role.

I also ran through the dsim and sfc suggestions from other forums.

I was trying to remove the RD terminal services, which I was successful in doing, but IIS didn't get removed along with it. Now manually trying to remove IIS will not work. Same error as you.

Hi Lei,

Thank you for your answer. Trying to uninstall IIS through PowerShell, I've received this error message:

"The request to add or remove features on the specific server failed. Removal of one or more roles, role services or features failed. Error: 0x800f0922".

I can't remove manually the folders because "there are files opened by other applications".
