How to start IIS after Denwer?

Question

ASP.NET

Hello!
A few days ago, to run a PHP project, I needed to install Denwer.
Today, it was necessary to debug the project on ASP.NET. But as it turned out, IIS does not start.
Error when trying to start Denwer using IIS Manager

Denwer uninstalled in the following way:

1. Stop Denver by "standard" means;
   
2. Delete local server;
   
3. Delete Denwer virtual disk;
   
4. Clear the system of shortcuts Denver.
   

OS: Windows 10.

Answer 1

Helped to roll back the system (System Restore) to the moment when Denwer was installed

Answer 2

Run Regedit Go
to
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP
, change the setting to 3
Start = 3
Reboot.
Ps if you change it to 4, then all the iis service will be blocked.
This is a kernel level driver for listening to traffic, and denvir can be run on other ports than 80 and 443.
