There’s a bunch of different ways to play with the registry in PowerShell. My latest script snippet that I wanted to preserve on here deals with a couple ways to add registry keys and values. For as cool as this is, however, I don’t believe PowerShell is able to make such changes to remote registries without using other methods. When in doubt, I guess I could just Invoke-Expression psexec.exe someregfile.reg and have it done there, but hopefully PowerShell gets remote registry scripting ability eventually, as this would be the next way to script mass registry changes to people beyond Group Policy.
