Using WMIC to find RAM info

The “Win32_PhysicalMemory” class is your friend here.

And to get the total number of slots in the machine as well as the maximum supported RAM, “Win32_PhysicalMemoryArray” is your friend.

Both classes have more properties than the ones I filtered for above.

Using WMIC to find machine info

I needed to find the model number of my Compaq Presario laptop today. The machine’s right next to me so it’s just a matter of lifting it up to look at the model number, but what’s the fun in that aye? Enter WMIC (via PowerShell).

The following WMI classes are useful in finding details of your hardware:

Win32_ComputerSystemProductFor manufacturer, serial number, UUID, etc. Does not contain the model number.
Win32_ComputerSystemFor manufacturer, model, physical memory, and details such as the owner name, whether it’s part of a domain, etc.
Win32_OperatingSystemFor OS specific information such as language, architecture, OS, registered user, etc.
Win32_BiosFor BIOS info such as the name, version, etc.

In my case WMI didn’t have the exact model number. But thankfully HP has a way of giving you the model number from serial number, and since I had the serial number via WMI I was able to get the model number without lifting a finger.
