The script will call this function and remove IE from Windows Server. If the user chooses to do so, it causes an expected restart to finalize the removal.

The function is being called AFTER the cleanup and after all components have been installed. It will not the script resume where it left off before the restart.

Suggestion:

- make the cleanup of components (at every run of the script) optional

  using WMIprovider is very slow, too and causes high CPU load.

- rehome the IE removal in the front of the script OR alternatively include a message that this is the last operation of the script and it does not need to be run again after the potential restart.

Please also include a clear warning that disabling IE, will break IE mode for Edge. It is prominently used for WSUS Update Import etc., not necessarily on a Hyper-V host though.

I do not see the reason why you remove IE, the package will also install MS Edge, if it does not already exist. Which is good enough.
