Hello SRIRAM A,

I see that application pools, sites, and applications are missing from IIS Manager after the recent Windows update. This issue appears to be caused after the recent windows update and can be cause by several factors:

Configuration version mismatch – In some cases the administration.config file under C:\Windows\System32\inetsrv\config remains on an older schema (e.g., 8.5) while IIS updates to 10.0. Updating or regenerating this file can restore the IIS console. You can check for the version at the path C:\inetpub\history
The user in this question (https://learn.microsoft.com/en-us/answers/questions/5542039/how-to-fix-iis-manager-ui-after-windows-update-(au) ) experienced the same issue as your and fixed it by correcting the version mismatch
Security software interference – Antivirus tools may block IIS components during updates. Temporarily disabling them, reinstalling IIS features, and rebooting often resolves it.
Corrupted or missing config files – If applicationHost.config or administration.config are corrupted, restoring from backup or reinstalling IIS may be required.
Group Policy or scripted removal – Some environments automatically disable IIS after updates. Confirm no policies or scripts are enforcing this.
System corruption – Running sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth helps repair OS components that may impact IIS.
If the above steps don't work, you can consider reinstalling IIS.

I hope this helps you get things back on track quickly!

Thank you!

Hello SRIRAM A,

Hope you're doing well! I just wanted to check in and see how things are going with the issue we were working on. Here are some additional solutions that are confirmed work by other user.

Solution 1: Restore from Configuration History

Navigate to the directory: C:\inetpub\history

Locate a subfolder with a name like CFGHISTORY_000000001x.

These folders contain backups of IIS configuration files.

Copy the administration.config file from one of these folders.

Paste it into the following directory, replacing the existing file: C:\Windows\System32\inetsrv\config Restart the IIS Manager.

The UI should now display your pools, applications, and sites correctly.

Solution 2: Replace Placeholder Token in Configuration File

If the administration.config file contains placeholder strings like: %WINDOWS_PUBLIC_KEY_TOKEN% This indicates that the file was not properly updated during the Windows update process.

Open the administration.config file in a text editor.

Replace all instances of %WINDOWS_PUBLIC_KEY_TOKEN% with the actual public key token: 31bf3856ad364e35

Save the file and restart IIS Manager.

This should resolve the issue and restore the IIS Manager UI to its normal state.
