Sometimes you just need a clear picture of what is in your environment.
Sometimes you just need to see how much disk space, RAM and CPU capacity a few dozen workstations have available.
Sometimes you walk into an office and you haven’t a clue what’s live, what’s turned off and what is very out of date.
This script fixes all of that. Give it a text file with as many Windows workstations or servers as you like and let it go off and get the version of Windows, the license type, the RAM, CPU, Hard disk capacity, the software and hardware serial number and the Windows installation directory. It saves this into a CSV file that you can then open in Excel to sort and play with as much as you want.
I wrote this to create an inventory of the servers in use here so I could see what version of windows they have, ensure they are using the most recent service pack and ensure they were all using the enterprise skew. I then expanded it to give me more information. Mainly so I can save it somewhere for use on a later date.
