 Run-SCCMClientAction -Computername $env:COMPUTERNAME -ClientAction AppDeployment

Answer 1

To run the script, simply make it part of a configuration item and add it to a baseline. Deploy the baseline to the collection where you want the script to run. Once done, the client will download a copy of the script and execute it.

That being said, also make sure that you have configured your client settings properly as you shouldn't really need to force these actions.
