If you’re installing IIS with Windows 7, you may find that the IIS (Internet Information Services) installation hangs while the progress bar indicates 100%. The menu displays: “Please wait while Windows makes changes to features. This might take several minutes.” and appears to do nothing.

The solution? Disable ESET antivirus and try again. I’ve found that it seems to conflict with the trustedinstaller which causes the lockup issue. It might be the same with other anti-viruses as well.
