If you think you need new environmental variables, consider how they are going to be used and referenced. Your PowerShell profile script may be the only tool you need.

One of the best new features in PowerShell 7 is the ability to perform parallel execution of script blocks, which can drastically reduce the amount of time it takes to process ForEach-Object loops.

You can find or see names and values of Environment Variables in using Windows Settings, Registry, Command Prompt and PowerShell.
