Powershell Audit workstations

Hello guys,

I am starting with powershell and I'd like to verify with you about how can I proceed with a work I need to do...

I want to create a script to audit workstations comparing the software versions with the expected sw versions... but I don't know the best logic for create that..

I thought about create two files. 1 with the results and another with the expected value and compare it in a foreach..

is it the best option?

I would like to confirm values as dns addresses, dhcp servers, domain name.. etc.

can you help me abuot how can I create a good logic for that please?

Thanks in advance
