"Installation of IIS7 under Vista" "An error has occurred, not all features have been successfully changed"

The server has been set up with Apache. Later, I want to use IIS to play. I found that no matter how it is installed, I get an error: "An error has occurred. Not all of the features were successfully changed!". The corresponding Chinese error message is: "There is an error, not all features have been successfully changed. ”

The premise is that I have logged in with administrator privileges, the anti-virus software has been turned off, but I still can't install it anyway. So google+baidu, a large number of people have this error, but did not propose an effective solution.

There was a problem when installing IIS. Later, I wanted to uninstall IIS and reinstall it. Uninstalling is no problem, but when the device is reinstalled, the system prompts “ There was an error. Not all features have been successfully changed, and I found a bunch of tutorials on the Internet, all of which said to turn off the data protection function of the current system. I still have to disable all system protection functions, and then I have to reinstall the operating system, and then I have to reinstall the operating system. The same problem will occur. After trying more, I finally found the root cause of the problem. Every time the system prompts this error, the system log will display a WAS (full name Windows Process Activation Service) service error, and later found that when you choose to install IIS, WAS will automatically install, but when IIS error uninstall WAS was not uninstalled. After discovering this, I uninstalled IIS and WAS all together, and then restarted and reinstalled without this error.

The problem was successfully solved according to this method.

Although I rarely say that Windows is not good, like some people, Windows is not a bug, but this should be a definite Windows bug.
