Script to delete old installed PowerShell module versions

A while ago I wrote a script that report all the previous versions of PowerShell modules that have been installed.

I’ve now done a script that will allow yoru to delete all these previous versions while retaining the current version. You’ll find that script here:

https://github.com/directorcia/Office365/blob/master/psmodules-del.ps1

# Example usage:
# Remove-OldPSModules                                                  # Process all modules without confirmation
# Remove-OldPSModules -SummaryOnly                                     # Only show summary info, minimize verbose output
# Remove-OldPSModules -ModuleNames “Microsoft.Graph”, “Az”            # Process specific modules
# Remove-OldPSModules -ConfirmUninstall                               # Ask before each removal
# Remove-OldPSModules -WhatIf                                         # Simulation mode, no actual changes
# Remove-OldPSModules -ModuleNames “Az” -ConfirmUninstall -WhatIf     # Combine parameters as needed

You can modify the execution part of the script at the bottom to suit your needs.
