This script works like a charm.
As promised it is very fast and solely takes a registry value instead of having windows search for updates (which almost always leads to a timeout).

There is only little glitch though:
When Windows was NEVER updated, the script will return an error stating that "CDate" cannot be created with a NULL value.

I fixed it by editing the script thusly (maybe if someone has a more reliable check for NULL, please feel free to add a it):

[Snippet starts at line 26 of check_win_lastupdate.vbs] ----------------------
strComputer & "\root\default:StdRegProv")
objReg.GetStringValue HKEY_LOCAL_COMPUTER, strKeyPath, strEntryName, strValue

'-----------------------------------
if IsNull(strValue) = -1 then
Wscript.Echo "CRITICAL: Patches have NEVER been applied!"
Wscript.Quit(intCritical)
end if
'-----------------------------------


InstallDate = CDate(strValue)
CurrentDate = CDate(Now)
[...]

----------------------------------------------

Thanks for the script :)
