>3 versions NOO! Maybe there is one 5.x? You should get rid of these. Version 1.0/2.0 is called 'WindowsPowershell' (powershell.exe), it's usually in your System32 for compatibility reason. 'PowerShell7' (pwsh.exe) is the modern one. It Imports most Modules/Scripts from the former, except for 3 Modules or so which are incompatible.
