Yes, it is possible for Windows. I don't know how to grab the info for
other OS's though. There is a caveat that is annoying. If the software
doesn't put itself into the registry somehow, it is much harder to
discover if it is indeed installed.
For hardware, you'll need the WMI module and the win32 module. For the
computer memory and the name of the PC, see below:
c = wmi.WMI()
for i in c.Win32_ComputerSystem():
mem = int(i.TotalPhysicalMemory)
compname = i.Name
For the CPU:
for i in c.Win32_Processor ():
cputype = i.Name
For other cool WMI tricks: http://tgolden.sc.sabren.com/python/wmi_cookbook.html
For the majority of the software on your system, you'll want to
iterate over the following registry key (and its subkeys) using the
_winreg module and WMI's Registry() function:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
Some code that worked for me (may need modification for your setup):
from _winreg import HKEY_LOCAL_MACHINE, KEY_ALL_ACCESS, OpenKey,
EnumValue, QueryValueEx
r = wmi.Registry ()
result, names = r.EnumKey (hDefKey=HKEY_LOCAL_MACHINE,
sSubKeyName=r"Software\Microsoft\Windows\CurrentVersion\Uninstall")
for subkey in names:
try:
appFile.write('++++++++++++++++++++++++++++++++++++++++++++++++
+++++++++++++++++++++++++\n\n')
key = OpenKey(HKEY_LOCAL_MACHINE,
r"Software\Microsoft\Windows\CurrentVersion
\Uninstall\%s" % subkey,0, KEY_ALL_ACCESS)
try:
temp = QueryValueEx(key, 'DisplayName')
display = str(temp[0])
appFile.write('Display Name: ' + display + '\nRegkey: ' +
subkey + '\n')
except:
appFile.write('Regkey: ' + subkey + '\n')
except:
print 'Error opening key'
# appFile is where I write the list to. You can just print to console.
That should get you going.
