If you have installed WMI (Windows Management Instrumentation) there
is a way to check just about everything (via Com/Automation), although
simplicity is in the eye of the beholder.  You can get WMI from MS's
site, if you haven't installed it yet.


>>> from win32com.client import GetObject
>>> cses = GetObject("WinMgMts:").InstancesOf("Win32_ComputerSystem")
>>> for cs in cses: break

Now you have in variable cs a WMI object of Win32_ComputerSystem class,
and you can query it to your heart's contents about all of its properties.
See for example the summary at URL:
http://userpages.umbc.edu/~kbradl1/wsz/ref/WMIref.html


>>> pc.TotalPhysicalMemory
u'234278912'
>>> long(pc.TotalPhysicalMemory)/1024
228788

etc, etc.


For a general introduction to "Microsoft Windows Management Instrumentation
Scripting", see (a single URL, split by posting):

wmiscript.asp


It's a huge, omni-comprehensive, some would say over-engineered system,
but once you have installed it correctly it does make it a snap to
perform every kind of monitoring and sysadm task you can possibly
imagine (and then some).  All you need to use WMI is any COM-capable
scripting language, and Python fits the bill wonderfully well.
