windows 10 – Update system powershell

I want to update the “system” PowerShell, the one accessible through WIN+x i, I cannot copy over PowerShell 7 files to the system PowerShell, as it is always in use. So I am suspecting that the system should be untouched, if there is no way to update it, is it possible to reroute the mentioned shortcut to run PowerShell 7?
