Summary: Use a free add-on to directly access scripts and modules from the Windows PowerShell ISE.

 In Windows PowerShell 5.0, I can access the TechNet Gallery for PowerShell modules, but is there an easy way
           to access and search the older Script Center Repository from the PowerShell ISE?

 In the PowerShell ISE, click Add-ons, select Script Browser Add-on Tool, and then follow the
           step-by-step instructions.
