Error with ProcessGetStats monitoring a system process

[readmedottxt]

Info - Win7 Enterprise, UAC off, attempted with/without 'Run as Admin', AutoIt 3.3.0.0

Here's some simple code that works properly with any process running as the logged in user account but fails to obtain details for any process running as SYSTEM:

$gui = GUICreate("", 400, 300)
GUISetState()
$label = GUICtrlCreateLabel("ProcessGetStats test", 10, 20, 380, 200)

for $i=1 to 60
    $mem = ProcessGetStats("wininit.exe", 1)
    GUICtrlSetData($label,  "Read Bytes: " & $mem[3] & @CRLF & _
                            "Write Bytes: " & $mem[4] & @CRLF & _
                            "Other Bytes: " & $mem[5] & @CRLF)
    sleep(150)
Next

It always errors with the following:

>"C:\Program Files\AutoIt3\SciTE\AutoIt3Wrapper\AutoIt3Wrapper.exe" /run /prod /ErrorStdOut /in "C:\Users\admin\Documents\AutoIt_Projects\Beta\test_ProcessGetStats.au3" /autoit3dir "C:\Program Files\AutoIt3" /UserParams

The changelog says bugfix #501 in version 3.3.0.0 resolved this issue. Is this a new Win7 problem? Is there a fix using the existing build because I have a lot of code using the InetGet functions and it will break in the newer release.

Thanks

I installed 3.3.4.0 on another Win7 machine and the problem is still there.

Have I made a mistake with the code?

TIA

Some more info,

It works when you append a second .exe on the code, eg:

$gui = GUICreate("", 400, 300)
GUISetState()
$label = GUICtrlCreateLabel("ProcessGetStats test", 10, 20, 380, 200)

for $i=1 to 60
    $mem = ProcessGetStats("wininit.exe.exe", 1)
    GUICtrlSetData($label,  "Read Bytes: " & $mem[3] & @CRLF & _
                            "Write Bytes: " & $mem[4] & @CRLF & _
                            "Other Bytes: " & $mem[5] & @CRLF)
    sleep(150)
Next

Bug or my mistake?

[readmedottxt]

Nope I was wrong, it's not reading the correct process. If you put a process that doesn't exist, it supplies erroneous data or the current process.

It fails whether I use the PID or the name of SYSTEM processes.

Still stuck

Hopeful bump

You might want to read about "Protected Processes" here: MSDN: Process Security

I'm by no means no expert in this kind of stuff, but it would certainly make sense to me

if processes like wininit & winlogon fell in the 'Protected Processes' category ...

HTH,
