4 years ago Optimize-Offline does NOT remove PowerShell ISE from Windows. PowerShell ISE is now a FOD that can be SELECTED by the user to be removed either using its Capability Package or Cabinet Package. The only PowerShell variation Optimize-Offline does anything with automatically is the DISABLING of PowerShell 2.0 because it has been labeled a security risk by Microsoft, as detailed in the ReadMe. Moreover, this is simply the disabling of the PowerShell 2.0 Optional Feature, which can certainly be re-enabled during runtime if so desired. Optimize-Offline does NOT remove any PowerShell version. It never has and never will.
The removal of PowerShell ISE would only occur if it was selected for removal.
Why OO tool delete Powershell ISE from Windows? I know, that is the part of hardening of OS, but is it necessary to remove ISE? Later, there are some problems with reinstallation.
